What are the pros and cons of it?
I saw the "guide" that one of the dev's wrote about it but it just gave background, it didn't really say WHY you would want to use it.
Speed improvements?
I saw he mentioned that it can help stop bottlenecking dalvik cache/ JIT. Does that mean it'll help speed things up?
*My bad. I thought I was in general but I have multiple tabs open. If anyone would like to move this thread or simply delete it that works too since the question was answered.
Con: potentially complicates backup and restore, especially if the dalvik cache is moved to the SD card. (Requires the user to understand exactly how it works, and how it differs between ROMs to avoid running into subtle problems.)
Pros: Gives you more space for apps, eliminates the need to re-download market apps when loading a new ROM, and allows you to back up your apps.
Highly doubtful you will notice any speed improvements.
Please ask a forum admin to move this thread to the General forum; it has little to do with development.
Unless you are running a Class 6 card, you won't notice any speed improvements (and it won't be significant with Class 6).
You use A2SD to get more apps on your phone, without the restriction of internal memory.

So I would have a speed boost with class 6, just not noticeable? What about a class 10?
you'd probably be looking at upwards of $100 for a class 10 sdcard... and even then, i don't think you are going to get the performance you want.
what exactly are you looking to do? LOL... just seems like a lot of money to invest for such little gains (i.e., you probably won't tell much, if ANY difference... IMO)
Oh no I wasn't planning on doing this lol although I am getting a class 4 card because I'm going to use my stock card for something else.
and an 8GB Class 10 is about 65 dollars at the JR near my house. I was just curious because they mentioned the dalvik cache being transferred to SD and how this apparently stops "bottlenecking" JIT functions.
I have an HD2 with SPL 2.08 and radio 2.15 , WinMo rom - Dexter .sencity 21.11 .
I have tried with other combinations too. My SD card is the original class 2 2gb micro SD. When I install Desire rom it works fast and everything is fine. When I put a Desire HD rom however it is slow - i takes 1-2 secs for it to open keyboard or the menus and so on. I dont know what the problem is or how can I see exactly how slow it is. Any help would be much appreciated! It is odd that people report that the Desire HD roms are really fast when they are slow on my HD2. Probably I messed up something but I dont know what so please HELP! I have tried different roms from m-deejay and Sergio76 and so on. The Froyo stock roms also work fast and flawless. I know there is another thread but it is in another section and there are no responses because this sections has 100x more activity. THank you!
Man honestly to rule out any possibilities of the ROM being the factor you have to use a class 6 or above sd card, otherwise you have no way of really troubleshooting what your problem is. Also, Devs mention in the releases all the time the Radio and WinMo ROM they use so to insure the same performance they can only give you what they are running as well.

The class of the SD card has nothing to do with it. The majority or people that have tried a class 4 and above say it is a lot worse than the stock SD card. I have tried and it was a lot worse for me also.
The Windows ROM and radio can have a LOT to do with it though.

By the way, how long exactly did you give it? These HD Roms can literally take hours to settle in and they won't be real speedy until they are completely done syncing everything. I have noticed that sometimes you won't see the sync icon but things will still be syncing in the background, inlcuding the Android market because these new Roms backup all your apps and data with the market and HTC sense. I am using Sergio76's and it is flying so I would try again but give it a lot of time to settle. Hope it works out for you, good luck!
As Motoman said, it will take time for everything to sync, but many reboots is very important. I have been using Mdeejay's Desire HD 4.1 for three days now, and don't have any problems. I must have rebooted 8-10 times the original day and that helped extremely well with speed.

At worst a class 6 card (for example) might not provide much in the way of an improvement over a stock class 2 but there is no way it would be 'a lot worse'.
Personally, I noticed a speed increase on identical builds when I swapped from my class 2 to a class 6 but nothing too drastic.

I agree with motoman that sdcards have nothing to do with the speed they might make a very little difference which can be negligible, I am suffering from a lot of lag in desire HD builds............
@motoman234, so can you tell us how exactly we should install these desire hd roms ?,
i was having the same issue with the hd roms. i thought they were terrible. i now have MDJ FroYo HD v.4.3=-[kernel:MDJ S7.5HD] running very well. i had to change my rom to achieve this. the wmrom is useless IMO but it lets me run android hd now. i am using this rom
ChuckyDroidROM-HTCFrameworkEdition.Nov.05.7z
and this radio
Radio_Leo_2.15.50.14
i also install bsb tweaks in winmo and set to power save mode. turn off everything in winmo and auto boot to android with hard keys lit up.
it works for me
Same issue as OP here. All non-HD ROMs run really fast. But other Desire HD ROMs are plain terrible speed-wise. I have a good Class 6 card.
It's a kernel issue. There is nothing you can do.

To each is own I suppose. I can only speak for myself when I say that a class 6 card made me have SOD every time when waking the phone from sleep, not to mention overall less performance. Not sure what it is about them but it was bad in my case but I doubt every single person will experience this.

It is a bit time consuming to get them rolling smooth for the first time but these are the steps I usually use when installing them for those of you that can not get them running like they should.
1) Boot up the build (fresh start)
2) Wait a couple minutes before unlocking the screen for the first time.
3) Setup everything in the SetupWizard.
4) From the moment you hit the "Finish" button on the SetupWizard, set your phone down for about 30-45 minutes before touching anything (OFF the charger if possible since it can get really hot when it is syncing everything for the first time. Charging can just add to that heat)
5) After you notice things to get a little faster, reboot the phone and then boot back into Android.
6) Wait another 5 minutes before unlocking the phone.
7) You should be good to go, if things still seem a little laggy try to reboot one more time.
I know this seems overboard but these HD builds have a lot to them. After you get the process over with you should be happy you did it. Once again **This is just what works for me** I am using Core Droid V0.2 by the way.
@Motoman234,
Not overboard...it's good advice. Thank you for the steps! P.S. Good to see a chef from my neck of the woods! Thank you sir!!

The Speed of the SD card has nothing to do with the roms performance.
The only difference that we will feel between a 'Class 2' and a 'Class 6' is when copying files to or from the SD card.
I noticed that on my 16GB Class 2, I have a transfer rate up to 4 MB/s when copying the Android folder and this card is supposed to have a maximum of 2mb writing while on my 8GB Class 6 I can copy up to 10 Mb/s the same Android folder (twice as fast).
But when Android runs I don't feel any difference at all.
The reason why the Desire HD roms are slow on the HD2 is because these roms were optimized to work under 768 MB RAM while our HD2 has only 576 MB RAM.
We barely have 100MB of free RAM with a Desire HD rom but with a stock rom we can have 300MB and more free.

I think what makes it worse is that we dont get 576mb ram in android, as this has not been built into kernels, we are only getting about 350mb of ram. If I check my available ram it is around the 300mb mark and has never been above 350mb.
u must just reboot you device after 1-st boot

Yes,the secret of having a good performance on any device is to have 1/3 of the amount of RAM always free.
For ex if you have 3GB of ram,you can use till 2GB and you will be very good.
But if you use 2.1 GB of the 3GB then don't think twice and upgrade immediately.
We are using this equation on our servers and t works pretty well,at least for our company.
I've only tested desire_hd beta and Core Droid HD v0.2 so far. Nonetheless, both have been quick and solid here. Like mentioned by motoman234, give these builds time to sync your market apps and settle down, then reboot a couple times, and you should be good to go. If the build has heavy lag, it's most likely still trying to download your market apps and install them as well as sync your personal data. Patience is key here.
Also, this goes for every build, but make sure that your keypad lights are on when booting into android. Doing this has normally solved any high standby battery drain that I've run into to date.
As far as MircoSDHC cards go, I have tested a handful of different class and size cards with the HD2, and found that once the system is booted up, there's no difference, or the higher class cards have more SOD or freeze issues for some reason. The HD2 can only handle so much, and random read speed appears to be the most important factor. In turn, a good quality class 2 card should be all you need. That said, I've been running a Sandisk 32GB class 2 card for months now, without a single problem to date. Regardless of what card you use, I highly recommend using SD Formatter in quick format mode.
Another thought... it may help a little to use a standard wallpaper at first, instead of the live wallpaper, just until the system has settled down.
All that said, I'm a huge fan of Core Droid HD, due to the animations and polished theme work done by Sergio76. It's an excellent build, and you can easily get the camcorder working with the system files fix included in the thread.
On a kind of related note, motoman234 has an excellent EVO Sense Black & Blue Remix build available, if the Desire HD Sense builds are too heavy for your needs.
Best to all,

So I have been searching the forum for a while but haven't been able to piece together a good answer from what I have been reading, so I decided to go ahead and ask. I know that these questions have been asked before, more or less, but at the rate development is going, and with the updated Android builds, I would guess things have changed even from 2-3 weeks ago, let alone 2-3 months.
What are the advantages of a NAND build (nowadays anyhow) over SD? Is it the speed?
Is battery life better on NAND or SD or it is really up to the kernel?
Are RAM editions somewhat speedier than their counterparts? if so, are they less stable or something than a regular NAND or SD version? I mean, if they are equally as stable, why isn't every developer doing RAM versions to get the most possible speed?
I know the speed of the SD card helps with SD versions to some extent. I bought a 16GB class 10 Wintec for that purpose, and it seems to do well. At that point, battery nonwithstanding, would be it worth it to go to a NAND build or would the speedy MicroSD make up most (if not all) the difference?
Thanks for the answers in advance. I just wanted to get a little bit of updated info from those in the know
While I am at it, another question to add to the list.
Does the underlying OS make a difference with the SD build? I know that Android should shut down and supersede the WM drivers, but would having WM7 over WM6.5 as the underlying build make any difference whatsoever to anything when booted into Android from SD?
thanks!
Main advantate of NAND is that you can replace SD card without turning off phone. And your build don't rely on speed of SD card. But due to small storage space, many builds still use SD which kinda defeats it's purpose.
Sent from my DL DesireZ 3.3 final using XDA App
No one has any idea on the other questions? Thanks for your input matejdo.
Again, some info is appreciated.
SD/RAM/NAND?????????????????????????/
I would really like these questions answered too.
I know that so far NAND is more complicated ....
with 2 or even 3 partitions, from EXT2/3/4, < who knows which is best.
And NAND is not as fast as RAM obv but is much safer in regards to corruption.
I have found SD builds to score higher in flops and quadrant than NAND however which is strange. SD is easier to copy to device, other than that im sure all custom roms have their issues. including screen light on lag.
i have tried and loved darkstone ram edition which was rapid but just not all there is you know what i mean, and now after giving up on dandiests desirez3.4/5 in nand and sd after too many lags, crashes and data drops etc im looking at MCCM HD V4 or MCCM GB1.8 SENSE GINGERBREAD as these seem to be the most stable build with all functioning functions but i shall soon see how they fair.........
.............................greatest respect goes to all devs for you efforts
we're nearly there!
but please any input regarding these questions would personally b appreciated!
Ok, here's my 10 cents. Some of this is debatable but these are pretty standard answers.

Yes, speed, responsiveness, battery life, etc.

Battery life is typically better on NAND. Kernels can also make a difference.

Technically, RAM editions are faster but they are worse on battery life. Data stored in RAM requires constant power and does not survive a power cycle of the phone, therefore the data is stored typically to SD card, which also consumes more power.

They say NAND write operations take longer than an SD card but for the life of me I still find it faster when a ROM is running completely off NAND than off NAND and an SD-EXT partition. Or, NAND versus full-SD- there is a huge difference in responsiveness between read speeds. They are much faster on NAND than even a fast SD card.
Hope that helps...

It can be more complicated... until you do it once or twice and fully understand how it works. Now that this has all been out a while everything is starting to standardize and more and more ROM's are using the same partition layouts. From a performance perspective there really isn't anything noticeable between EXT 2/3/4.
Oh, most ROM's now also use CWM, which along with an SD-EXT partition can leave you with up to 7 different partitions on your device. Fortunately, you don't really have to manage any of them as the ROM's do all the work once you've set it up once.

This is due to a slower write speed of NAND storage versus SD storage. But, because the read speed of NAND storage is higher you still get an overall feel of greater responsiveness and speed even though the scores are lower. NAND ROM's are easier to backup and manage via the CWM aspect.

Possible problem may be higher amount of RAM needed. Especially sense builds would need a lot of RAM.
I have to disagree with a lot of what the post above mine said... The main difference between NAND and SD builds is with NAND builds you can use clockwork recovery, remove and replace your SD card while booted in android, and maybe a few other small improvement in stability and performance, but nothing too noticeable. Speed and battery life are about the same. You might get a little better battery life on standby with NAND. I generally got 3-5ma drain on standby with NAND, while I get 4-6ma on standby with SD. Speed and performance are pretty much the same because when you're running something with either type of build, it does it from RAM with either type of build. When an app or a process is running, it goes into ram, regardless of where the info was stored. NAND and SD are just the 2 options of where the data is stored when it's not being used by ram. Actually, the NAND in the HD2 can be slower than the NAND in good quality SD cards... but the random access speed is good in the HD2 NAND. But with a high quality SD card, you can get just as good random access speed with SD. That is what makes the performance difference with different SD cards... when the OS is trying to access small amounts of data or write small amounts of data, different SD cards will take different amounts of time to access... and the class rating of the card has nothing to do with that... in fact, class 2 cards tend to have better random access times than class 6 or 10.
But anyways, if you have a good SD card, performance and battery life are about the same... depending on the build of course. Desire HD builds tend to run a little better on NAND... but some recent SD DesireHD builds are good, too. AOSP and CM builds run pretty much the same off of SD and NAND as far as I can tell.
RAM builds work by loading more of the OS files into RAM at startup so that the random access speed of them is improved greatly, since RAM is the fastest memory and where any data is loaded to run anyways... it cuts down on the need to access the SD card for as many small system files, which improves performance and battery life in theory. The RAM is used anyways, so it doesn't use any more power keeping extra data in RAM, and since the SD card isn't accessed as much, it saves power there. But SD doesn't use much power anyways, so it's not really a noticeable power reduction. Also, RAM builds are still pretty experimental, and can have problems with data corruption... if any changes made to the os are not recorded to the SD, then if you lose power suddenly, there can be problems. Also, keeping all those system files in RAM causes you tohave less RAM available to run other apps and such... thats why there's no RAM builds for DesireHD builds, because there's not enough RAM. Personally, I never noticed too much of an increase in RAM builds performance compared to other AOSP SD builds like JDMS. Also, I'm not sure why, but I don't think RAM builds worked very good with NAND. But in theory, the system files in RAM is a good idea, especially for SD cards so it takes some stress off the SD cards. When running a build off SD, your accessing the SD to read and write system files while also accessing it as normal to run your apps or play your music or other data you have on SD. Keeping system files in RAM cuts down on the work the SD needs to do in the same way installing android to NAND does... then the SD is just used to access your media files or apps or data.
So in the end, it all depends on what you want from your phone... if you are not going to use winmo or wp7, and only use android, you might as well put android on nand, even if the improvement isn't that noticeable, because you can then use clockwork for easy updating or flashing roms, and you can change out your sd card, and there may be other small improvements. But if you still use winmo or wp7, then you have to decide if it's worth losing the ability to run more than one OS to give your android the added functionality of clockwork and other improvements. I use android on NAND for a month or so, but I didn't like how it turned my phone into just another android phone... it couldn't do anything that you couldn't do with a desire or evo or other android phone. But with the ability to run winmo or wp7 also, it's the only phone that can do it this well. When wp7 was released for the HD2, it was perfect for me because I wanted to try that OS out, and now I love that OS almost as much as android... I would have a hard time picking between the 2... luckily I don't have to. No other phone can run both of those OS's, either... I feel like I'm really making use of my HD2. If I just wanted android, I would've bought a native android phone from the beginning. But the great thing about the HD2 is no matter what OS you want, the HD2 can do it. People who want just android can make their HD2s almost like a native android phone now that it has clockwork recovery support. People who want 2 OS's can do that too. Android runs great from both SD and NAND... so use what works for you.
the battery life in android roms, is better than original windows mobile?
speed battery and efficiency are the main reasons
Yes it has a beter battery life (imo)
Ram is faster memory wich will make everything very fast, but you have to fuzz with Windows Mobile (?) to get there and that is what people dont like, the I/O on RAM is very fast, thats nice and makes quadrant scores very high
Class 10 card is good for SD versions, but imo that is very outdated, NAND is the way to go, like real Android devices loaded from the phone memory, not ram or sd, wich gives a beter battery life and fast speed (almost like stock) .. and also important , no fuzz with Windows Mobile.
And rest of the data wich isnt on your phone mem can be get of your SD card with a NAND version, cause the phone mem doesnt have rly that much space left after u installed Android on it (enough for enough apps though), class 10 mostly means a faster speed, so it will benefit you in some way

I beleive that the custom android roms do last longer than original winmo. I love this 2.3.2 rom on my HD2. 2.3.2 on my gf's mytouch 4g last about 18 hours on moderate call/text/ use with overclocked on 1.3

for ex in win mobile, using the hd2 moderatly, how long the battery survive? and in android?
Wow! Lots of great info here!
I have been playing back and forth with different OS's and builds and SD builds and NAND builds etc. My phone is probably screaming at me to give it a break
As per responsiveness, the NAND builds (non-sense) seem to be a little snappier than the SD ones for me. The battery life seems about the same. Haven't had a problem with NAND space as I bought a US HD2 with 1 gig of ROM space, which is plenty for me. I haven't actually delved into the WM7 yet, but after reading this, I think I might give it a whirl and see what happens.
The biggest difference for me between the Android Nand/SD builds was the initial loading times. Which makes not that much of a difference because I tend not to turn off my phone anyhow.
The 2nd biggest difference is the wake from standby. On almost all the SD builds I tried, I would hit the hangup button, and the screen would come on in like 1/3-1/2 a second. If I accidentally hit it twice, I would have to wait 3-4 seconds for it to work properly again.... more presses seemed to do nothing. On a NAND build, it seems like the screen comes on instantly, and does not have the repress issue. But, then again, this is not a big issue for me at all.
The fastest build, by far, that I have tried so far is the Hyperdroid v5 build. It really does respond faster than almost anything I have put on the phone.
Thanks for all the answers people! It really helped to fill in the gaps in my admittedly shaky knowledge!

i understood it quite well..i think u have alot of valid points.. There arent big differences between sd/ram/nand...its a matter of choice imo..

if its on sd card it will still load into android after turning off everytime right? i dont want to see windows anymore at all

I have to disagree with a lot of what the post above mine said... The main difference between NAND and SD builds is with NAND builds you can use clockwork recovery, remove and replace your SD card while booted in android, and maybe a few other small improvement in stability and performance, but nothing too noticeable. Speed and battery life are about the same.....

Thank you for your post it has the best thought out points for and against, and greatly helped me in deciding which build to go for.
All right so this may be strange but...
I had no problem creating a bootable SD card for the Nook Color. Wanting the latest and greatest, I went for CM9.
I got Samian's larger CM9 image file so I could use the cm9 nightlies, which are too big for the boot partition of CM7 build.
Anyway, it all went great. Smooth as butter, no crashes, no fuss. So far everything works....EXCEPT, I don't know exactly how it IS supposed to work, since this is the first and only android device I've owned.
So I am in the strange position of having no real technical issue -- but I do have significant "user" questions.
Here are a few. 1. Android Marketplace seemed to install fine. But I end up going to google play when I hit the "shop" button. Is that right? Or is marketplace some kind of integrated app I should be able to use without google play coming up?
2. Can I access the files on my internal Nook Color memory -- i.e. can I read my books, or do I have to put them on the SD card?
3. Are all my apps always on? Is there a way to "shut them down"? Do I need to? Coming from a PC environment, I like to shut down a program when I'm not running it.
4. My "system" information shows (when look at running programs) that I have only about 500MB of RAM. Is there a way to use some of my SD card for more RAM -- or any other way to increase it?
5. Any kind of general user guide for CM9 out there? I realize there probably wouldn't be one specific to Nook Color, since in a sense this is very elaborate hack, but I am starting from scratch.
thanks so much. I've enjoyed the messing around, and I'm thrilled at how well it's gone so far. I got a lot of info from xda.

1. Market just was upgraded by google to Play Store. So it is operating properly.
2. You can access files from internal media memory (emmc). But you may have difficulty reading the nook books stored there. They are encrypted for your nook account (DRM). But you can install the android version of the Nook reader and log into your account and redownload them to your SD.
3. Don't worry about always on apps. Android was built for multitasking and has a very efficient memory management system. It does everything for you. It puts apps in memory for you so that when you go to them they are ready to start. Just being in memory is not using processor time so it is not a drain. Also Android will automatically remove apps from memory if it needs to.
4. Because of 3 above 512MB is a lot ram. There is really no need to expand it.
5. Off the top of my head I don't know of a manual, but I'm sure there are some out there. Just google search.
Most of the questions are Android related matters, so any google search about general Android, would do the job.

Thanks Guys, I appreciate it.
Two follow up questions:
I am running ICS/CM9. Only been at it a day or so, but so far, no real problems. The screen might be *slightly* less responsive than the NC system, but it's not clunky -- maybe just a little slower, a little more prone to having to tap some things more than once.
1. I've seen many other posts of people raving about CM7 and how stable and zippy it is. Would I benefit from switching to CM7? Is it faster/more responsive than CM9 currently?
2. I was thinking of just finding another cheap micro SD and installing CM7 on it (rather than the dual boot thing, which would require me to wipe my current SD and start over). Any reason it wouldn't work to run CM7 off a different card?
thanks again!
It would be worth it for you to get another SD card and load CM7 on it to see the difference. I have used both CM7 and CM9 and love the interface of CM9 but do prefer the stability of CM7.
Learning your way around the systems can.be daunting, but stick with it - Google your questions, read the forums here. You will learn loads just using your nook.

RevTom,
Only use a Sandisk Cl 2 or 4 microSD card for an SD install. Others don't work as well. This has been well documented here on XDA many times.
There is a high likelihood you will have a bad experience if you don't follow this advice.. (force closes.. slow response, ramdom re-boots, etc)
Search the web.. they are about as inexpensive as the rest. Sometimes Radio Shack has a decent price on them.. sometimes not..

1. Just a little faster, more stable. But you give up the tablet interface.
2. Only reason not to is inconvenience of manually switching the cards and of course your media files go with each card. But it will give you a chance to look at it and decide which you want.

Yes, I've seen those threads -- maybe I can add some new info. I went with a SanDisk class 6 16GB. I didn't see the class-rating discussions until too late. There are some who also recommend staying 8GB.
However, with CM9, I've had no trouble using the class 6, 16GB. Maybe I just got lucky, or perhaps CM9 can handle the 6.
I'm glad your class 6 is working for you. Have you seen Racks thread in the development section for a dual boot SD card with both Cm7 and Cm9 on it? I did that for awhile. His instructions are pretty straight forward. You can have your books, pictures, music, etc. on the.SD card and use them with both systems.

Yes, I've seen the the thread. I would still have to wipe what I have so far, and I like the version of CM9 I've already got -- believe it came from someone called "Samian" or something like that.
One final question. For a single-boot SD OS, anyone have thoughts on the best CM7 to run with?

Some swear by Mirage by mr666. It has been customized heavily so I personally like stock CM 7.2 RC3 from the Cyanogenmod site.

My own setup involves Cm7 at main memory with 233 nightly and sdcard with Racks dualboot (kang Cm7 and ICS).
You should consider the fact that its easy to try other systems by just swapping Sd cards. Then you will find what you really like.
Unleashed from my Nook Color at 1.2G
Here's where I got my original CM9
android.sphsolutions.net/Encore/Nightlies/Misc/
The "generic 1.3" creates a larger boot sector to accommodate the larger cm9 nightlies.
Since the first post, I left that one on my larger, faster card (class 6, 16GB), and tried Racks' Dual boot. Cm9 seems to run a little zippy-er there, but I can't tell if that is the build or it is the fact that I'm running that one from an 8gb class 4 card (which is said to be better than a class 6).
Still favoring ICS/CM9 over CM7.
Any thoughts on file management for the free SD space? I am having mixed results with plugging the Nook into the PC. Sometimes I have full access to the free space/storage on the SD, and sometimes it shows up without any folders or files at all. (this is in Racks Dual boot, CM9)
Also, anyone remember off-hand where I can find the thread that tells me how to make CM9 the first (primary) boot instead of the secondary? I've traveled so much ground in these forums lately...
I'ver got EU HTC HD2 and want to install Paranoid-AOKP-JellyBean. As you can see there are 2 versions of this interesting ROM:
NAND: http://forum.xda-developers.com/showthread.php?t=1817793
and
SD: http://forum.xda-developers.com/showthread.php?t=1793180
It's written elsewhere SD Androids can be used as dual-boot together with WindowsMobile (or with WP). It sounds perfect but there should be a price for this. That's why please explain me what is the superiority of NAND version of this Paranoid (and of all NANDs in general)? Thank you!
NAND = faster than SD but limited space fo apps, use link2sd/ap2sd or the like
SD = almost on par with nand but sometimes can slow down, Big storage for apps
i use both NAND & SD to boot Andy
Thanks for clarifying this. I always wondered the difference as well.
And to make sure
NAND is limited built in memory but stable
Sd is greater space but isn't always as stable because of class? Or is there another reason for that?

I "guess" the class doesn't have much impact since that speed is mostly for READ/ Wite/ Copy, I used both class 4 & class 10 & sometime I find that the class 4 is even more stable.
SD could be slower/ unstable might be because it needs to access some data/ memory & fetching could cause some mishaps - i guess :silly:
I use SD Android for over a year and truth is, since few months I didn't found any fast and stable build like those on NAND. Well, maybe on Gingerbread there were few ones that worked well, but since ICS was announced there always been some problems.

i have only experience of darkstone superram froyo on SD, never tried NAND, but i've been amazed with how fast and stable that is.
i only installed it recently to get wifi tethering with my blackberry playbook but if i'd known how good it was going to be and how easy to set up i would have installed it ages ago.
the fact that i can revert to winMo at any time by rebooting makes it a no-brainer.
SD Android might be unstable because most SD cards aren't used to have such a high load all the time and often they end up with data corruption, so chkdsk every week gets into your routine. That makes NAND ROMs superior to SD ones.

Maybe, but it doesn’t change the fact that NAND is still better choice than SD.

However the main concern reported elsewhere was these SD Androids consumed much more energy so this resulted in quick battery drain. Would you confirm those reports?

So then what about NAND ROMs with scripts like Apps2SD? If you move most your apps into SD card then won't they exert too much load on SD card too?

Is Paranoid-jellybean also among them?
Other question: it seems SD ROMs save NAND memory since elsewhere it's reported NAND memory wore too, especially under intensive writes, so maybe would the SD ROMs be the remedy? How do you think?

TBH I've used both forms of Android and neither seems to have exerted strain on my SD card very much. At the very least, my SD still appears with the same amount of storage it originally came with.

Correct, repeated writing of the NAND (especially for those people who think Task29 helps when it doesn't) can cause bad blocks which cannot be written to and eventually may make the phone unusable. However, having done a fair amount of flashing my phone I don't think I have many bad blocks. If I do, then they haven't actually affected me yet (i.e. I can use the recommended /system partition without having to account for extra space from the bad blocks).

Hi.
So that means flashing to NAND is limited? And it's better to use SD ROM's. How do I find out if and when the NAND becomes bad blocks.
Thank you.

Why not Google/forum search that? And when you say limited, you mean that there's a limit to the number of times you can flash, right? Well if there is one it's incredibly high, and it certainly isn't better to use SD ROMs as they're much slower and consume more battery.

Nand is much faster as it uses the ram rather than having to read the SD card and then put it into the ram so speed is visibly slower. I use a nand ROM but with a2sd support. That wat you get the speed of a nand ROM but the app space of an SD ROM.. best of both
