I have a PNY Class 6 8GB MicroSD for my phone. I was wondering what are the benefits of a2sd, and what are the benefits of a class 6 SD rather than a lower number? I don't currently use a2sd, and wondering if i should.
lower number is slower. iirc, the Hero supports speeds up to class 6, which is faster then the phones ROM

Ok, that makes sense, but why should I use a2sd? How is it better than storing them on internal memory?
if its a class 6 it will load faster.

Ability to have more apps installed, as well as not having to wipe all the applications when you flash a new ROM (although some require you to wipe the ext partition, the ROM chef will tell you if you need to wipe the ext parition (where your apps are stored).
I didn't think I would ever need A2SD until I got to my limit.
I have not noticed a drop in performance opening apps with A2SD on my class 6 card, if there is, its milliseconds.

A2SD moves all of your installed apps to the SD card. If you have a class 6 card, which have a faster read and write speed than the internal memory in the phone, it makes everything run a lot faster since it doesn't have to run everything from the phone.
sorry to get off topic a bit, but ive been looking for a good class 6 card. the only brand i have seen is a-data i believe for about 20 dollars. im not really looking for something that has a large capacity. in your opinion, which one is better as far as brand? and how much did you pay for your card?
One thing to remember though is that class 6 just means it is certified/guaranteed to transfer at 6MB/sec or faster. A class 2 card can still be as fast or faster than a class 6 and there are some out there that do just this.

I wouldn't... every A-Data sdcard I've ever bought has developed bad sectors almost immediately.
Sandisk is the standard, but a class 6 SanDisk is hard to find. The last few I bought were Transcend.
How do you tell what class your card is?

It's on the card itself. It's the letter C with a number inside it. That number is the class number.

thats what ive always been looking for, but as you said its hard to find. if you dont mind me asking how much did you pay for your card and what size is it? also, thanks for the heads up on the a-data card.
I read a review not long ago about sandisk class 2 cards. the tests they ran on them showed they were the equivalent to 10 mb/s. of course you would have to get the right batch number. does anyone know a site that tracks this kind of info?

Depends on how you use a2sd.
If you move dalvik-cache to it as well as your apps it'll be a lot.
But the total amount depends on the number and size of the apps you have installed. I'm sitting with 126/160mb free on Internal Storage.

+2 I have a Class 2 card and I get around ~7+MB/sec, I'm tempted to bump it up to run A2SD more aggressively so that my phone's faster.
i was thinking about buying a class 4 16 gb Sd card.. will this help at all i am not running app2sd..so will the sd card make any difference??
Will it make my screen run smoother and fast on Damage Control 2.8??

If you're not using a2sd it probably won't make much difference either way. If you're thinking of running a2sd later spend the extra 10.00 and get the class 6. regardless of the people talking about their high speed class 2 cards, you'd have to be fairly lucky to get those speeds (as someone else noted, depends on the batch of cards) with class 2, or 4.
an also if i run app2sd if i pull out my memory card at anytime will it mess up my phone??
and i have the 1st class right now so upgrading will make no difference when downloading apps to my phone or anything like that??
I'm new to android phones, and have a very noobish question. I'm wanting to upgrade the SD card in my g2, and am not sure what I should get. I wanted to get a 32 gig card, but I can only find class 4 cards, if I drop to a 16 gig I can get class 6 or class 10 cards. Which one would be the best, I run psx4droid so I do have the games on the card. Other then that everything is ran from the phones internal memory I think, so would a class 4 card be fine or does it really need to be class 6 or better, also is class 10 worth the difference in costs?
I'm still using the stock sd. I don't run games though. Its up to your personal preference. If I was to upgrade i'd get top of the line. They do make a difference in classes but I don't think enough to the point where it will effect your psx gaming. My 2 cents is to go with what your comfortable with.
[G2/HTC Vision]
the classes refer to write speed so dont worry
I'm using a SanDisk 32GB Class 2 card with my Nexus One and it's working well. Speed tests have shown that it is performing slightly better than the Class 4 level.
Thank you everyone for the timely responses and information!

Hello everyone,
This is my very first post. Sorry if its redundant one. But i couldnt find any thread with this specific problem.
Here is the thing, i bought HTC legend just 2 weeks ago. I have unrooted legend with Froyo 2.2 vodafone update. Yesterday i bought Kingston 8GB class 4 microSDHC card. I placed it in my legend. It detects it no problem formatted it. But it seems whenever any application tried to write to sd card. I get the message "SD card unexpectedly removed".
I have tried formatting card with Panasonic sd card formatter . Tried formating it under windows. The card works fine on PC read/write. But for some odd reason phone can only read from it
Also stock 2gb card is working like a charm in phone.
Please Help!
Try with some other brand
Usually Kingston has lot of duplicates especially in India

Yes i did consider that possibility. But the thing is card is working perfectly fine in pc. I have 3MB/s write speed when i copy things into card using pc. So if card was not original it shouldn't work even under windows. It just doesnt work with legend.
If i shall not find a suitable solution here. I will be left with no choice but to spend more money. Try ScanDisk.
Anyone??? I dont want to end up buying another card just to find out it doesnt work either.
man i have the same issue using kinsgton 8gb microsd hc, for example i do some photos, and on the 5th one, it says unaable to save file do unsuitable permissions or smth like that...it also mixes my music in a way i cannot imagine ! ahah, it puts like..5 songs into 1 without any pause ...dont know. the stock one is perfect, but i just guess theres problem with the company..they might be fake.
Try to enable usb debugging mode.

5MB/s minimum. If class 5 existed
Here is the definition of the class for sdcards :
Class 2 : 2 MB/s minimum write speed
Class 4 : 4 MB/s minimum write speed
Class 6 : 6 MB/s minimum write speed
Class 10 : 10 MB/s minimum write speed
However, certains class 6 are less performant than certain class 2, so try to choose your new card wisely.

Hi! Check the lock switch! maybe its turning on when you put the card into the phone...
I had kinsgton 8gb microsd with same problem
work fine on PC with low read/write rate and my HTC legend rejecting it sometimes saying i don't have permission over my SD
anyways, this was due to corrupted SD card. I replaced it and everything works fine now
I had kinsgton 8gb cls4 microsd with same problem
on my LG OPTIMUS ONE with froyo
it notify me with msg "SD card unexpectedly removed"
some time after this notify msg my phone reboot ifself

I'm really not certain about this, but their a limit on the size SD card our hd2's can support. (Either 16 or 32gb which is what I'm uncertain of) try formatting your new SD card into two 16 gb partitions and then see what happens.
Hopefully either that helps or someone with more knowledge than I will comment and give you a better answer

Well the limit is definitely not 16gb because I have one of those and it works fine in Android but it for some reason cannot boot SD Android. Also, if I'm not mistaken MarkAtHome (I've seen him in many of the NAND threads, especially NexusHD2) has a 64GB SDXC card as he was posting something about that a while ago. He'd have to confirm though.

Where did you get your memory card?? You son are a victim of false advertisement. I purposely purchased a "cheap" 16GB sd card from ebay and it wasnt even bigger than like 300MB. There are ways to fake the memory size, and thats why when you try to put the music on your card is says its not there because there truly isnt any physical memory available. And also why it gives those weird readouts. Sorry to bust the news :/

There have been threads discussing how certain sd cards do not perform well in android devices, including the HD2. It has to do with some of the access times the cards are rated at.
I have tested a 32gb patriot class 10 card in the HD2 and samsung vibrant that made both phones freeze and run terribly slow until the card was removed.
Sandisk cards run flawlessly in the HD2 and I have only been using them for the past year, including a 32gb and a 64gb SDXC. The 64gb must be formatted as fat32 inside the phone before it can be used, but the full 64gb is available.

I agree with elesbb. Infact the same thing had happened to me about 4 years ago. What they do it put a memory hack in the SD card fooling it to think there is more memory. I would say if you bought it from ebay contact the seller first and
tell them you think it might be fake and you wish to get a real card asap. If they don't send you one or sound like they may be un-willing to then you should report them. Here's some information found on ebay's site about fake memory cards.
If you bought it from a different online seller you should still contact them about it and say you did some research and believe you recieved a counterfit item. In the link i shared above there are a few examples of how to spot fake cards including some pictures if you go through the links. I've read somewhere that if you have a sandisk and the class rating is in the corner then you more then likly have a counterfit one. Sandisk's class ratings should be centered in the middle of the SD card.
Okay, i've just sent email to him, hopefully he will just re-send me new, (working..?) or give money back!
I was wondering if it is possible to use a 64 GB microSD card with my MT4G. If so, what ROM do I need? I searched and the only thread I found was a thread from 2011 saying that the cap is 32 GB because that is the limit of microSDHC. I found a good deal on a 64 GB card and would like to get it if I can use it.
Yeah it will work, but you won't get the claimed speeds due to our old hardware.
Just format the card in the phone and you're good to go.
what is the speed I will get with the card? I'm looking at a class 6

Not sure. I'm doing research on this. I know the card will WORK on the mytouch 4G, but I don't see any mytouch 4G specific speed tests. I saw where a newer phone got better speed on sdxc class 6 than sdhc class 6, but again that's newer hardware.

What kind of speed tests are you guys looking for? I have a 64GB microSDXC card in my MT4G. I'd be willing to run a couple tests if you guys are looking for any specific information as long as you tell me what you want done.

A lot of the performance gain seen with SDXC cards comes from the new file system included- exFAT. ExFAT is not supported on our device, at least not in any ROMs I've used since getting mine. I'm not sure if different ROMs can include the necessary changes to allow exFAT usage. If I had to speculate, I'd say it probably depends on firmware updates to the card reader in the phone that we likely won't ever see.
Instead, to achieve functionality, you must use your phone to format the microSD card before it can be used. As a result, we won't be able to see all the benefits the newer, higher capacity cards have to offer. An SD booster application may still be able to speed things up a little, just as it could with the older cards. I just wouldn't expect too much.

My microSDXC card is a Sandisk Class 10 200x 64GB SDXC. The formatted capacity of my card is 59.4GB. I have about 31GB of free space. This card was NOT empty when I ran these tests. I'm not sure that would effect the tests at all, but if so, this should lean more towards real performance rather than results you'll never see once you start using a card.
Here are a few speed tests:
