With class 10 mSD cards, is it technically possible to have RAM on SD?
Got it on win XP. That would help overcome the problem with JB running low on RAM.:victory:
I think you mean swap?
I'm sorry, I'm not into swap and such so I can't give you additional information, but hey, that is a head start .

Well u can use the app called swapper2.it will create a swap file on sdcard and give u more FREE ram

thanks guys, will give swapper a try.
Guys, you all got it wrong.
RAM is very fast RANDOM access memory. It means it got low latency and high bandwith, no SD card is close to that performance.
Also SD card class 6+ is all about sequential write/read.
RAM is all about random data access.
SWAP is a slow, temporary storage.

I'm planning to get a microSDhc card for my Jade (HTC Touch 3g).
Can you guys please advice will there is any difference in performance, response time and speed between 4GB microSDhc and 8GB microSDhc.
For the timebeing, I'm using mere 1GB micro SD card and its works great.
I know that both works with Jade, but how about the response time? I'm surely looking for bigger space, but not at the cost of speed and response time.
Thanks!!
HTC (officially) supports only 4Gb SD. Many I know have used 8Gb without problem. Personally I'm using just 4Gb without problem. Response time - blink of an eye, I do not have an empirical engineering measure though. Most of my programs / applications are on SD and the response time are OK.. so far, over a year now, never fail.
I use this one without any problems:
http://www.amazon.de/gp/product/B001D0ROGO/ref=ox_ya_oh_product
I have no exact data for response etc. but it is very fast.
I am using an 8gb, I can't compare it to a 4gb since I don't have one.

Thanks Azahidi for the info!!
Even i'm planning to have my most of the programs/appilcations on the storage card, so was wondering about the response time.
On HTC site, they said they have tested 8GB, but didn't mention about the performance.
http://www.htc.com/in/faqs.aspx?p_id=174&cat=270&id=85794&f=t
But, the salesman at the store said 8GB will make ur device slow, which I didn't want for more space.
So, was looking for the expert opinions on this.

Have you guys installed programs/applications on the Storage card?
And is the reponse of those program on SD are marginally slower as compare to similiar application on device memory?
Even I'm looking to bigger space, it helps a lazy person like me to clean the storage after long long time.
How is the access time for data like music/video/documents from SD and how about the stability?
Thanks in advance!!

I installed nearly all programs on my card (see above) and I have no delay or other problems with it. Of course I do never remove it.
Speed for Cards...
most of the new Cards u can use have different "class" of speed, it give class
Class 2: 2 MByte/s - 13x
Class 4: 4 MByte/s - 26x
Class 6: 6 MByte/s - 40x
i use a Toshiba 8GB with Class4 (i pay 8,-EUR at eBay) and this works fine.
The most of the Programms I use, I installed on the Card except Phoneweaver or eqal Software that use direct access to the Sim.
I use for Videos (MusicClips, TV-Series with Subtitle in srt-format and Documentations) the CoreMobileVideoPlayer and the Videos works fluently perfect.
I have a second Device, a HTC Diamond with internal 4GB and to this it is no different with the speed (memory access).
I hope, this helps a little bit

Thank you so much!!
It is a great information you shared and really helpfull for selecting my Storage card.
well i use an 8GB micro sd card and it works like a charm
besides i heard that our jade can hold up to 16 GB's (thats what the folks at htc store told me) not quite sure about it but i guess the more storage u ride the more battery consumption u get
so i guess its fairly enough to stick with 8Gigs.
HTC touch 3G ( jade 110)
Hi guys. (I own htc touch 3g- jada 110) I am using also 8gb SDHC (kingston) class 4 and I recomend this one. Its fast, cheap (ebay- just be aware of some cheap replicas). I have also tried this card on my girlfriend`s htc tytn 2 (kaiser) and worked as well. So highly recomend KINGSTON cards.
I have both the 4gb and 8 gb Sandisk micro sd card. I can't tell the difference in speed and am very happy with the 8 gb card! Am thinking of upgrading to the 16 gb for my movies though!

Thanks for the information!!
Let us know your feedback after using 16GB, if things are stable there..... then we might think of switching to 16GB for the obvious reasons...
OK so I've been running many version and builds of android since day one on my tmous hd2. At first it was with the stock 16gb sdcard, (till it got corrupted, LOL) so then I switch to a 2gb I had around. I have only formatted this 2gb card once in the begging and never again.many times I have deleted the android folder and many times I has switch to new builds ( I think I try everyones.latest I been using n very stable JDMS 1.3) n haven't had any issues. Like freezing or SOD. Now two days ago I help my friend with his and his wife's tmous hd2 with the 16gb card. So I did a fresh format fat32 then flash the same rom (ozDroid) and radio I been using for months. It results they are getting freezes and occasionally SOD. So for a test I took my wife's tmous hd2 with 16gb card did the hole setup an guess what the freezing and SOD is the more often..when I don't get any with my sdcard 2gb. Could there be an issue with high capacity cards. And could that be the reason why many tmous have the more problems with freezes and SOD

this is common knowledge in the IT field. the larger the card, the more slowly it will write and access small files, such as the files needed to run android. take 100 small text files and copy them to a 256 thumb drive, and an 8 gb thumb drive. you can copy them all to the 256mb drive, and delete them all again, before the are all copied to the 8gb thumb drive. the 8 gb drive, will work much faster copying an .avi, or large file than the 256, but it sucks at lots of small files.
but it's good that you're posting your exp here. many people would not know this otherwise, and may stop experimenting with android due to frustration, when all they need is a $10 2gb card from walmart.
another couple tips when dealing with solidstate memory. just like a harddrive, files can become fragmented if you have multiple tasks or file transfers going at the same time. to avoid this, make sure each is done before starting another set of files. next, do not defrag solid state drives. they only have a limited amount of times they can read and write to each sector, and defragging, and excessive copying/deleting, wears down the material, and kills sectors of the drive. and last but not least, watch your battery. just as it says not to attempt an install with less than 50% battery, don't run your phone down to a dead battery when possible. because your booting of the microsd, it's constantly being accessed by read and write functions, and if the battery dies before it finishes writing, you get corrupted files, and you'll have to do your install all over.
No lockup or freeze with 16GB.

Same here. 16 gb SDHC, no problems.
I haven't noticed any difference between a Class 2 2gb, Class 2 16gb, or a Class 4 8gb - they all run about the same with not noticeable differences in boot time, smoothness, or SODs, even though the class 4 is 2x as fast.
hi guys,
before you post any comment, you can grab a none SDHC card, and do a comparison.
if you have benchmark software, please look at the "access time", the None-SDHC card always faster than the SDHC card. not the speed, but the access time.
after I change to 2GB SD Card, I never meeting any sleep, lag program with any version of roms.
if you don't have none-SDHC card, please do not make any conclusion.
16 gb class 10 kingston sdhc
works great
compaired a class 6 no name 8gb sdhc and the stock 16gb class 2 the class six lags less than the class 2 but the class 10 16 gb kingston is super fast
I am using class 4 8GB and 16GB, no diffrence found.
I can confirm, going from 16gb to 8gb, I've had far less issues with the 8gb card using the same setup. 0 SODs when I'd get them daily with the 16gb card. May or may not have anything or everything to do with it, but I'm sticking with the 8gb card. lol
My experience has been that performance has been about the same whether using a 2 GB SD card or a 16 GB SDHC. However, it seems that my 16 GB card was slower at one point because I had an excessive number of individual files on it. It's a double edge sword because you have all that capacity but the more you use it the slower it seems to run.
I had this issue aswell but I updated my radio to 2.12.xx.xx. and since then I have not seen any performance issue due to the SD card size.

That's very presumptuous of you.
I fixed all of my lag and screen freeze problems with a combination of setCPU settings, ADW launcher settings, and updating my radio rom.
Before I finished doing all of that this morning, I'd get a freeze from wake fairly often. Since then, not a single freeze, and trust me, I've been trying to get it to freeze up.
Believe what you will my friend, but punishing yourself with a 2GB card just seems silly when people are outright telling you that the size isn't the problem.
Good luck either way!

Yes ur are right with the new builds and using setting and programs like setcpu or even auto killers will help eliminate this problems. But I I said in the first post was that high capacity cards tend to give u more problems, using my 2gb (I think all the way to 6gb is non high capacity) I have no need for such adjustments to whatever build I use..u can read post 2, is very well explain there.

Hello All I have a very simple question but plays a very important role in performance.
I got a 2GB SD CARD FROM SAMSUNG.
I have another LOCAL SD CARD 4GB
My question is will the SPEED Remain same to transfer or access data from both these SD CARDS.
I mean to say is will the LOCAL SD CARD BE SLOWER(since its not samsung branded) IN ACCESSING AND RETRIEVING DATA which will eventually slow down my phone or something like that.
I hope you all understood my question..will elaborate if u want me to.
hoping for a good answer.
Thanks
so many views yet no replies
cumon guys a small opinion would make a big difference
I am not very knowledgeable about this, but the class of the SD card matters when comparing performance. Here is a link that might help:
http://www.sdcard.org/developers/tech/speed_class/
i have noticed that when i changed sd card from samsung original (came with phone) to new transcend 8gb sd card, phone is now booting for 5 minutes....
It being a samsung card doesn't make the card more "compatible" with a samsung phone. A card is defined by the card, not by the brand.

yeah so it means that performance has degraded right.
Also i think booting is not much worry as its done from ROM
so apart from booting what else is buggy or degrading performance,comparing both 2 GB and 8 GB
its on a card to card basis, if it is slower for him it doesnt mean it will be slower for you.
You should use a Class 6 SD card. Slower cards are not adequate.
Sent from my GT-I5801 using XDA App
You can use a class 6 SD card, however, i do not think the phone is capable of handling such high speed cards, and thus the read/write speed of the phone will limit the speed.
Conclusively i don't think there will be an increase in performance!
Hi,
I am using an 8GB Class 4 MicroSDHC card for booting my Android ROM,
Would upgrading to say an 32GB Class 10 MicroSDHC improve the running speed of the ROM or just the data transfer ect.
I am booting Via Haret.exe using stock WM6.5 if this helps,
thanks,
Alex

Good to here, will save me £70
In my experience I saw that most of the ROMs, scripts and kernels are kind of limited to, or working best, with certain classes of SD cards, i.e. higher is not always better.
Also, in order to get the best performance with your card's SD class you have to adjust the readahead buffer to match it.

There was a thread about this ages ago if I'm not mistaken but as a very general summary, no. Stick with classes 2 and 4 for running SD android. Save yourself some money!
I think it's more dependent on brand. Try Sandisk or Kingston (seeing as you're in the UK) they're good quality. Just a heads up if you ever want to try MAGLDR and dual boot with Windows Phone 7 or NAND Android, Kingston 16GB Class 4 SD cards don't work with MAGLDR for booting SD Android Works fine on winmo though.
From my understanding (I'll try and find a reference) but class 10 cards achieve there speeds through sequential file systems while class 4 and 6 are non-sequential.
This would seem to mean that class 10 would always be markedly faster than class 4/6 but android can only make use of non-sequential so you won't notice the increase in speed.
You will notice the difference when transferring thing across from PC to the card using a reader, but as I understand it class 10 won't increase substantially of a SD card ROM.
Now a follow up question:
If you run a ROM of the sdcard does that mean that the sdcard's lifespan will be greatly reduced as it's constantly being written to and flash memory deteriorates overtime/numerous write cycles?
I have a Nook Color that is rooted running CyanogenMod 7.1.0 on internal memory. I have a 16GB Class 10 SD Card in it and was wondering what people are using for partitions on their SD Cards. I have pushed pretty much every app over to SD Card but some (not all) applications (Google Maps for instance) seem really sluggish and many times it force closes.
Is the Nook just not powerful enough to run Google Maps or is there something I need to adjust? Maybe a bigger swap partition? I set them up quite a while ago and don't recall what I set them to off the top of my head.
Using CyanogenMod I am overclocked to 1.2GHz with the Governor set to Performance.
VM heap size set to 48MB.
Thanks
class 10 cards are not as good as you'd think for any Android device. Android devices tend to write smaller files... a class 4 card (Sandisk recommended) is actually best for these devices.

I am mainly using Class 10 as that is what I had laying around in the Micro SD Card Format.
I have a 32 GB Class 4 in my Thunderbolt and it is fine. Do you really think it would slow it down much if it is Class 10? I could always toss it in an adapter and use it in my Canon T3i.
This thread here explains what the issue is and will tell you how to test your cards out to see if they'll work. Basically that Class10 card only gets Class 10 speeds when transferring large files and for small files (like an OS/app uses to write temp files) you get crap speed. it's not normally noticed in everyday use because the files are small and a little delay writing it isn't noticed by the user. Class 4 cards from SanDisk seem to be overall performers for files of all sizes.

Hmm, that is interesting. Now does it matter that I am booting off internal memory? I am not dual booted and have CyanogenMod on internal memory. I am running Google Maps which is one of the programs that is really slow on internal memory. My guess is that what you are saying would apply because of the swap space being used on the SD card. I will say that my wife also has a Nook Color that I put my old 8GB Class 6 card from my old Nexus One in and hers seems to perform a little faster than mine. I haven't done the tweaks to VM heap size to hers that seems to have helped mine a little. So you may be on to something. I have a couple of these class 10 cards that I use on my Camera and have been happy with them. I think they are Samsung. The DSLR is 18MP so those files are pretty big so it might be just better to leave those cards for use there and get a couple of those SanDisk Class 4 cards for our Nooks.
Yeah, running apps from the sd would benefit from a fast sd card. When you get one, use CrystalDiskMark (pc) to check the 4k read/write speeds. I bought an 8gb and two 16gb Sandisk class 4 cards from Radio Shack that have reasonable speeds and work well. They're all in the .5 range for writes - not as good as some I've heard of, but they work well! Some (a Kingston and a knockoff Sandisk) I tested were as low as .006! I tried to use the Kingston before I tested its speed and got lots of instability and FCs. hth
