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,

Hi guys,
While I am respecting and thanking all devs for their hard work and time , i would like to share this thread with the guys who are not happy with nand and went back to window rom with sd card based android built. and the reasons for that
I used NANDroid for the last couple of days and felt missing something. From NAND i did not get big advantages as expected.
reasons are (please do not get offended this is my personal experiance)
1.nandroid internal memory is not enough to save lot of applications
2.Even after Data.img is created in some builts using app2sd it is too laggy, i feel the lag in SD built is better than NANDroid
3.what is the point of using android alone as i could buy a cheap wildfire for £100 brand new handset.
4.some applications can not be ussed in ANDROID like tom tom and Garmin( i dearly miss TOMTOM as you all know NO.1 SATNAV in Europe
5.whatever we do the HD2 hardware is not fully support to NANDROID like native android as this phone is designed for windows
6.some SD builts like mdeejays desire HD 4.6 and cedesmiths desire HD and darkstones superRAM are better equiped than NANDROID.
7.if I use SD build android it will be 2 in 1 and i can get both experiances.
those are the reasons i went back to SD card based built which is Mdeejay desire HD 4.6.(cheers mdeejay)

hi friend
I was using that before but when you install more than 10 apps from market or back up you data you will get warning 'low memory'.
Got to disagree with you OP. I think NAND is the best thing to happen to the HD2 since android was first ported. Im using HD2one build and it freakin awesome. The battery life is also spectacular, especially in standby. Can now run a full working day (9 hrs) and still come home with 60%+ battery life, with SD i was lucky to come home with 30%. Just my 2 pennies .
Ricey
I don't have the ability to try out the NAND ROMs (broken microUSB), but I am still thrilled that it can be done by others, if only for the renewed dev interest in the HD2, and more options for people is always better. But even if I could flash an Android ROM, I think at least for now I'd stick with WinMo and SD builds (more options is better). But surely with a little time, the NAND ROMs will surpass the SD builds in terms of stability, usability, and performance overall. Once we can flash Clockwork Recovery, and use ext2 a2sd, NAND will beat SD hands down. But even with that, having WM plus several Android builds and Ubuntu on the SD is a very attractive option. For me, multi-functionality will be preferred to stability and battery life. But to each his own, more options is better. I just hope the SD builds don't fall by the wayside, they still have alot of use left in them, and for those like me, theyre the only option.
~HD2 Android~
I will most likely go back to my tried & true SD builds because you can't update these ROMs with new kernels or framework of desired launchers. And regardless of what anyone says about changing kernels, I can't do it because I have no clue what ADB is and nobody explains it.
My SD versions work just as good as these ROMs and boot up in 1/3rd the time. I kid you not, it takes on average about 4 to 5 minutes to boot the Gauner or cmylxgo ROMs. And there is no stock m-deejay DesireHD ROM.
I can see the problems of the original poster as I'm in the same situation. The gauner build is nice and all, uses little battery and is snappy enough, it is lacking some important features (like led notifications). The speed difference is not as massive between nand and a fast sd build. Gauners build is just a bit snappier than mdjs Froyo HD 4.6, but the difference is hardly worth getting rid of the advantages of an sd build in conjunction w/ Winmo.
If m-deejay did a nice NAND build of his 4.6 I'd flash it right away, but it's nowhere in sight. First reason would be a fast and snappy, stable ROM.
Soon I'll go to a roaming country that I've got Tom Tom maps for, and I don't have igo. So I'll likely flash Winmo back and get back to MDJs HD 4.6 sd build.

A week ago I thought the same, using an EU HD2, you get half the internal memory of the US phones, tried a couple of recovery roms now using Jaws MUIU recovery and all I can say is WOW...a little confusing at first setting up your sd card partitioning and the setting up the recovery bit, but once done everything runs fast, slick and reliably.
I really did want to stay with windows mobile as I thought I didn't need android, but now I have android running so well I don't miss windows anymore, best of luck with your hd2 the best device

I'm back to SD purely because of the dual operating system, I find that making a call in poor signal areas wm is much better prob because it was designed for the phone.

This NandRom absolutely ROCKS!!!! Do yourself a favour and try it!!
Concerning TomTom: I do agree.. TomTom is by far the coolest Navprogramme, but Navigon for Android is actually quite good too..
Wtf lol....
NAND with data.img is much faster as a sd build,logical also:
You can see it as a pc with 2 harddrives in it,1 for the os,1 for writing data on it,so disc 1 keeps his speed (nand is this case)
I have zero lag using this method with the nand build that i use,and i am getting easy 2100 quadrant score on 998mhz ghehe.
No way that sd android is faster
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.

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.

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

No offense at all, but I really tried to read your massive wall of text but I got lost after the first sentence.
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!

Yeah, sorry about that... I tend to try to fit too much info into a post all at once and I sometimes don't organize it well. I'll also ramble on sometimes to get everything out I'm trying to say and it ends up making the reader miss a lot of the important parts.

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

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.
For some reason it just seems to be laggy, is there a cause or a fix for this? Should I re-install cwmwith bigger than a 150mb partition?

mine works great, none lag at all, you sure you have right CWM given by typhoon and you are doing ext4 partition for sd card, i have 1gb partition on sd and it works great as long as you install it correct you shouldn't have a problem, start with "task29"....
I did TASK29 and i'm sure I installed the right CWM software. How do I do an EXT4 format, I think I just did a FAT32 format to the sdcard....
Also, what I mean by laggy is that if you put a live wallpaper up the phones gets extremely laggy, no matter how simple the wallpaper..I'm comparing it to a samsung vibrant (galaxy s) and i'm assuming they should be the same cuz the specs are the same and the HD2 seems definantly more refined with android... Hell we don't even having working GPS for CM7 lol.

Tytung new 1.7 gps libs got working agps support..you can get a fix in 5-20 secs...
To create a sd ext, backup your sd card, then boot in cwm. I think it was advanced-partitoon sd card..or sth else...youll find it .
choose 1gb sd ext and 0swap...after that restore your files on sd card.
Concerning your laggy...can you run sd tools from market to test your writing and reading speeds?

You could try:
Slow SD card, Up the Read-ahead cache of the SD card, using the sweet little app SD Speed Increase, which is free on the market
Live wallpaper are lagging, and also battery eating (at least that's what they told me, but personally I don't use live wallpapers, so no guarantee)
Did you underclock your CPU?
Reflash your ROM, sometimes, things get clogged up (Happens to me too)
Oh and GPS doesn't work on CM7? Use the new Tytung GPS libs and you will have a fix very fast!

Thank you for advice.
I will test SD Speed Increase but i have found also SD-Booster which i think have the same effect.
What is your opinion about dorimanx typhoon tweaks?
I'm running a NAND build guys..... not SD

..i know, im using also the typhoon rom, but a faulty sd card could also slow down your device.

Sorry, I don't know about the dorimanx typhoon tweaks.
and @jwleonhart, I know, but a slow SD card will slow down your android rom in some cases, I've noticed a big difference in a class 10 and a class 2 card.
Its been a long time since I have used a desire HD rom, I think the last one I used was actually markinux's super light version back in early 2010.
Obviously a lot has changed since then, and Ive been with CM7 builds for a while.
I was wondering if there are any Desire HD roms, maybe with GB (not essential) which fit into the EU version without the need for an EXT partition (My SD card is very slow )
I only need like 60mb for apps anyway, is there anything out there?
I really miss sense and the high quality camera/ camcorder!

So far all EU Rom's need ext partition.
But no problem at all for me to go with ext..
and a new fast card is not a big amount. 8GB is ok
Are there not even Android 2.2 builds still out there which only get stored on NAND? I remember my very first NAND rom was a desire HD port, I had around 60Mb free after the install too.
