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?

I have a class 6 Transcend and use app2sd. Just wondering how much memory is it supposed to be freeing up?

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??
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.

You should consider that your card is a fake one ...

Any idea how much write speed a class 5 card should have?
Class 5 has minimum write speed of 5MB/s

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 was using an 8 gig class 2 that I have misplaced. It didnt run too well and my nook was laggy. I am hoping to get an 8 or 15 gig card. Which class will work best for rooting? Thanks

Strictly speaking any microsd card should work for rooting the B&N stock install on the built in memory. But if you are talking about booting from microsd and running a ROM, you want a Sandisk card.
I've noticed you've started a few threads now that could have been avoided with a little searching. Talk about microsd cards can usually be found in the first two pages of the Accessories subforum just by skimming the titles.
Most of the common topics will show up in the first three pages of any given forum.
Happy Searching,

I use Kinstom 32GB class10 early. But when I take photo, some photo maybe have error.
After that I check for internet about it. Someone said that maybe Kinstom's problem. It's not stable.
Now I use the Sandisk 32GB class4.
Maybe defy not support class10.
or that's Kinstom's problem. I don't know.

I bought a Team 16Gb Class 10 micro SD and it freeze my Defy, but I read that all Smartphone have trouble with class 10 cards (maemo and WP7 too).
It's something related to voltage (if you use setsvel to undervolt) and with partition (you need format the card with 32k or 64k)
I think Class 4-6 will be enough, until the Android Kernel will support class10.

Did you mean SD Class?
Just look at the card, it has either a 2 or a 4 or a 6 in a circle stamped on it. Thats the class. The class = the number of MB/S it can transfer.

No. Class=speed only. He said the partition have 32K 64K.....I think that is not Class. Because the class can't change when you format the sd card.

Using a class 4 32 GB Kingston since a few days, working nicely. Got 5.5 MB/s write, 12 MB/s read. Thanks for the info, I was going to buy a more expensive (and I though, more future proof and safer) class 10 one, before I read about the compatibility problems with class 10 here.

If you want to find out what partition your card is just plug it into your computer then mount as SD storage. Right click on the card from "computer" and select format. The default settings your card is set at will be shown. You can change it to other sizes, and formats (like FAT, NTFS, but FAT32 should be default and used for phones). I recently formatted my Samsung 8GB class 6 at 4069, and no issues so far. Don't worry it won't format unless you select to format, so you can do this just to check.
Hi there, because of this thread i bought a class 6 16GB Trancend SD card. Formatted it with 64kb clusters now have 11,2 Write and 21,9 Read speed (in SD tools).
Thx you all for the advice not to buy a class 10!

There are lot may apps & tools available which help us to get to know more & obviously get more from our SD cards.
I started this thread so that we can share ideas/tools/applications/scripts which are meant for our SD cards.
To name a few:
SD Tools
SD Speed Increase
Link2SD
Lets discuss on how to efficiently run our SD Cards & get more from them
Good topic Yin,
Ill just write something descriptive. Its really important to keep your storage area in good condition. It need formatting from time to time. Just shift all your stuff to your pc and formatt it and put things back again. It can make one helluva difference to the way your phone function, believe me.
If your phone has been giving problems and youve tried all methods except this then you know youve got to try this.
Also... Get a high class card. I was using 32gb class 2 and apps were crashing all the time. Swiched to a class 10 and never had an issue.

There is an app in market called sd speed increase which irrespective of card class increases read & write speed. Has anybody tried that.
