Hi,
Just wanted to share, how to check your microsd card class speed
(if its not specified on the box or the memory card itself )
http://en.wikipedia.org/wiki/Secure_Digital
Class Minimum performance
SDHC Speed Class 2 - 2 MB/sec
SDHC Speed Class 4 - 4 MB/sec
SDHC Speed Class 6 - 6 MB/sec
SDHC Speed Class 10 - 10 MB/sec
Link below links to a program you can download to check your microsd class/speed

Not in our country and other asian countries. As piracy is everywhere as you know. :fingers-crossed:
Most of the SD cards nowadays do not have labels this is why their selling it at a very low price.

It's better to use any benchmarking app to test sd speed what is said online is theoretical also this is xda u can U see fit

I think I read somewhere that it takes the class 2 only, which is what I have on my current Sandisk 16gb card.
I have been looking at 32gb from Sandisk and they seem to be class 2 only.
However, I saw a Kingston card that says:
Compliant — with the SD Card Association card 2.00 specification (Class 4 & Class 6) and with the SD Card Association card 3.00 specification (Class 10)
Rating Write Speed SD Class
(Mbit/s)
13× 16.0 2
26× 32.0 4
40× 48.0 6
66× 80.0 10
I would assume faster is to prefer, but will it work?
and would this be a better option?
Yes. Sometimes, but you probably won't notice it.
I have an 8gb/class 10 and it works great. I don't know that I can tell the speed difference ... but mentally I feel SUPERIOR!
It should be able to handle any current class.

You're definitely of my kind
However, it seems like the snappier card is mainly an improvement if recording or watching Hi-res videos.
Besides, I'm not confident that the post is a legit chip (though poster probably believes so), alternatively that the specs are incorrect. Kingstons site only states 16gb class 10, not a 32gb class 10.

I just got a Ridata class 6. The phone turns on much faster and video playback is not choppy anymore. SD card speed test reports it as class 6.

Hi all...had a query...When copying into my desire hd sd card- the average speed is about 2mb/s
Is it normal....any way to improve it?
If your card is a Class 2, then it's normal. If you want faster write speed, upgrade to a Class 4 or even 6 card.
Use a Class 6 SDHC card
Consumer mobile phones come with Class 2 SD cards, with a low read/write speed.
The fasted sdcard is Class 6, which offers very fast readwrite speeds.
but it aslo depends upon your pc hardware at read/writing. if you have a top end pc/laptop that capable of fast transfer speeds then yes you will benefit from a higher class sdcard. but if your hardware is limited then i wouldn't really bother, only saying this as the not cheap to buy esp when you get class 6 or 10 sdcard, mine cost £70 an i don't get that faster transfer speeds but that cause my laptop ****

try asking your local mobile retail shop .. you could also try ebay or something ...
Ps: note that you need a higher class card to record videos in 720p too. Atleast a class 4 is required for recording at 720p

Have a look at the card and check whether you see a 2, 4, 6... in a sort of an open circle (right side of circle is open) printed on it.
did you sd card come with your mobile phone? if so, it is very likely a class 2 sd card.
Hi there
i bought a A-DATA 16GB SDHC Card to improve my performance, but it seems to me that this card isn´t class 10 ,..
i tested with AnTutu System Benchmark and it told me
SD Card Write 7.4MB/s
SD Card Read 12.7MB/s
Could anyone with a Class 10 Card post here his scores and the brand (kingston, sandisk, etc.)
Thanks
Mine more or less has the same speeds and it's class 2. I bought it from play.com and it;s their own. That might be able to put it into context for you. Also, if you using A2SD then you can get away with class 4 or class 6 for DATA2SD.
...
Thx for your reply, but i m a little bit dissapointed that after over 100 views, no one posted his scores with an class 10 card or a different one.
so i cant be sure if the card is fake or not but i think so because your calass 2 card get similar results.
hope that someone can point it out with his results.
thanks to any help / result.
i really miss a micros sd/sdhc card review with recommened cards for the desire.
Gonna receive that very same card in 24/48h, gonna let you know my speed for reference!
It's said that the class level is actually measured by the block size of 8k, not the max speed.
ok just done mine 16gb class 10
results as follows
SD Card Write 12.9MB/s 129
SD Card Read 15.4MB/s 154
total score was 1696
whatever that means i dont jknow but i hope this helps

I get SD Card Write 5.4MB/s and Read 15MB/s on my SanDisk Class 2 card.
Are you guys getting speed using phone app? Which one? Did you also try in your computer maybe?
@teorouge
Read first Post, ... Antutu System Benchmark ... with this free app in market you can test your phone but the main part for me is the memory card writing/read Speed test.
@gav12345
Which brand is your sd card ? kingston, sandisc, transcent,... ? Please let us know, because there is a huge difference between your class10 and mine.

Please be aware that actual read/write speed deppends on applications and data2sd / app2sd scripts running. Anyways, A-DATA class 10 16gb is a very good card.
Maybe the card-reader in the Desire isn't fast enough. Anybody knows which class the card-reader is?

Also, whats an easy way to find out what Class your SD card is?
It is written in on the card itself.
Why two threads? This is not a news group.

The higher the class, the faster the card, max = class 10.
Class 6 card should be fine for speed and will cost less than a class 10 card which is only needed for speed freaks.

Just look on your card! On my Sandisk 16GB microSD there is an open circle with a number (4), this number is the speed-class!
Recommended for the Desire is Class 4 or 6, Class 10 seems to be incompatible with Desires Hardware and produces lags!

I use a 16 GB Trancend class 6 and it works perfectly. My 6 GB class 6 card was way faster though.
By the way, the method of A2SD used is also very important. SenseEvolution was a lot slower on my HTC desire than Mildwild and both use A2SD, though in a different manner.
I'd recommend a Transcend Class 6 for Data2SD

the rom is really fast and pretty darn stable but every time i open an app that downloads alot of data or is larger i have to wait from 5-15seconds for the menus to pop up, its basically just waiting at black or white screen, i believe this to be because of my sd card but im not sure... alot of apps are normal but some like facebook is the worst and whats app takes about 5-8seconds to open up fully aswel...
is there anything i can do ? i have a 16gb sd card
I have testet with benchmark and found, that the class 10 card has no more speed as the class 4 card. So what, i use the low budget but high capacity class 4 card 32 gb.
Thanks for your observations which are probably useful to someone interested in those kind of roms, but when you say something is...

Because sdcard and it's class is only one part of the coin. You have random i/o and phones memory controller. Any of the links in chain not working as expected (to be taken relatively as Desire was not intended to use >class6) and you'll get crappy speeds.
Sent from my HTC Desire using Tapatalk 2
Even class2 runs fine for me and it is faster than the specification since it does anywhere betweeen 3-5mg/sec instead of only two.
Its an original sandisk
I know, this is probably a silly question, but am I the only one that notices how devices only tend to label compatibility with Micro SD cards based on size, and not speed or class? For instance, my Galaxy Tab S2, it simply says it can take up to a 128gb SD card, but it does not say what speed it will work with.
The reason I ask, is that I am now in the market for a 128gb card, and yet I don't want to buy an expensive fast one, if my tablet will not be able to take advantage of the premium speed. Anyone have any thoughts?
I don't know about the speed but I have a SanDisk 200 GB that runs fine.
I think that any phone or tablet that will read 128 GB will also work with 200 GB.
Shofar
Don't worry
Any MicroSD card will work in your Galaxy Tab S2. But then, you might have to format it. When you buy the card, keep an eye out on the speed class- higher speeds are much better!
You are looking for a 128GB card, and I use one in my tablet so don't worry. It will work! But I seriously recommend a higher performance card because it can get very slow with cheaper cards.
Hope this helps!
I just tested a regular class 10 card and a UHS-1 card. Both tested at 9mb write and 40mb read. The same UHS-1 card tested over 40mb write using an Odroid C1 board.

I suppose that means that using anything above class 10 is irrelevant?

No, that means that "class" classification is outdated. Fast cards (read and write) bear the UHS-I "U3" classification, "U1" is slower.
In future, only buy U3 cards, like the SanDisk Extreme family.

I guess you missed the part where I stated that the UHS card had a write speed of 40mb using the Odroid C1 board. Obviously, when it only writes 9mb in the S2, then the S2 itself doesn't support the higher speeds. So, no matter ability the card has, if the device's bus doesn't support the higher speed, then the card's ability is meaningless. Any card you use is going to be limited by the bus speed of the device.
Paying extra for a better card is pointless if the device doesn't support the higher speed.

This was what I meant, I'll make sure to buy a decent one but not the "best". Quick question, how are the internal memory write speeds? Actually, what card should I get then? How fast is the internal memory write speeds? Thanks!
Just tested the 32 GB SanDisk Extreme (U3 but not an Extreme Plus or Pro) in my T815 with the "A1 SD Bench" app:
read 59,70 MB/s or 61,04 MB/s, write 22,75 MB/s or 24,70 MB/s. The second numbers are the result of using the "accurate mode" of the test app.

Why don't you install the A1 SD Benchmark from the Play Store and test your own cards? My internal storage rates 50mb write and 160 read.

I am using this SanDisk 128 GB Micro SDXC UHS-1 / Class 10 card and it works fine! The price/performance is good.
In germany (Amazon.de) you can get the card for 33 € (+shipping costs).

For our fast S2, this one is too slow in writing. Class 10 means only fast reading.
You better choose a Samsung or SanDisk with the "U3" designation, which means fast writing, like this:
http://www.amazon.it/Scheda-Memoria...sr=1-5&keywords=sandisk+extreme+pro+microsdxc
FOR EVERYBODY :
I have bought a LEXAR 633x 200GB !!!
And it works !
Speed : read 95Mo/s write : 40Mo/s
For 90$, it do the job very well !
The only better sdcard is the 256GB SAMSUNG but it's out of price !
So a higher performance card or 200GB eill make the tab s2 go faster then? What amount of storage and sd card do you recommend?
It won't make the tab S2 go faster. But it will allow faster read/writing to higher performance sd card compared to a regular one. The S2 can only go as fast as it's hardware can, with or without a microsd card.
Figured I'd share my results with my 2015 S2 8.0 (SM-T710). Right now I have a Samsung EVO Pro (U1) 64GB in my tablet and it does ok, but I'm just about to upgrade it to a new 128GB EVO PLUS (U3) card so got some results below. Note the previous 32GB card I had was waay worse, much older and only did 4MB/sec on writes (forgot the brand) but things have at least come a long way in the years since.
Results as follows...
Samsung EVO Pro 64GB (U1) - 70.53MB/sec Read - 72.86MB/sec Write (Fresh Format)
Samsung EVO Plus 128GB (U3) - 69.91MB/sec Read - 43.40MB/sec Write (Fresh Format)
Samsung EVO Pro 64GB (U1) - 70.07MB/sec Read - 17.81MB/sec Write (Only 4.9GB Free)
Samsung EVO Plus 128GB (U3) - 63.08MB/sec Read - 27.12MB/sec Write (Only 65.9GB Free)
For the heck of it tried the transfer rates on the PC for the 2 cards as well.
Samsung EVO Pro 64GB (U1) - 86.85MB/sec Read - 80.77MB/sec Write (Fresh Format)
Samsung EVO Plus 128GB (U3) - 87.04MB/sec Read - 82.27MB/sec Write (Fresh Format)
Though got to say while cards neck and neck, small file writes where 5x greater on the new U3 card (.5MB/sec vs 2.5MB/sec) on 4k writes.
