I've read many threads about certain apps needing a sd card of class 6.
I am currently using one that came with my HTC desire, which is a 2gb one.
How do i check if my SD card is class 6 or not?
Thanks in advance.
It is usually written on the card you may see a number in a circle. Benchmarking apps can also help, try antutu or sd card tools from the market.

iirc: the stock card is a class 2 card but a fast one (> cheap class 4)
Yep, the stock card is Class 2.

Any advice on which are the best higher class sd cards to purchase, taking into account cost, speed & reliability ?
play.com had a sale on some class 6 8gb cards. i don't know if they still do. i got mine from them.
One of compatible class 10 cards are from A-Data.
I also have class 2 4 GB card, SD tools can't detect the class and selects the "?" radio button. However the read are write speed are 23MB/s and 5.3MB/s. Is this normal?

It depends on the free space on your sdcard...
I have a Lexar 32GB Class 10 and when I have free space of 20GB the read speed is cca 35MB/s and the write sp. is 10MB/s. When a 10GB free space: 25 and 8MB/s.
EDIT: Can somebody confirm that I'm right?
EDIT2: MB/s not GB/s

To answer your question: No, those numbers are wrong. I suggest to format SD card with SDFomatter.

My question was concerning my 16gb Class 6 card (which actually appeared to be corrupt/broke'd anyway)
I asked about compatibly with the Desire...
htc said:
Thank you for contacting us.
In regards to SD Cards
I can help you with that.
The card that you are trying to use is not compatible with the phone as the class is too high speed for the device to be able to keep up with the speed. I have included a link to a webpage with the sd cards that are compatible with that device.
http://www.expansys.com/a.aspx?i=196001
If you look under the accessory tab then down the bottom is compatible memory.
I trust that this resolves your query, please do not hesitate to contact us again if required.

I'm sure I read some threads about class 10's working fine in the Desire?
The link seems to suggest only a class 2 or a class 4 will work...
I'm using a class 4 without problems so far.
On a dutch board I read a guy was using a class 6 on Starbust so it should be possible I think.
I've just bought a 16gb class 4 Sandisk and the speed tests show it as being quite a bit faster than my class 4 (non Sandisk) 8gb card!
I'm using class 4, working fine
I'm using a 8GB class 6 card with Custom ROM and A2SD with no problem. Been over 6 months now.
A lot of class 10 cards have issues, class 6 seems to be the most reliable thus far. Some people have had good experiences with A-DATA 16gb class 10.
So from user experience - a good Class 6/10 card should work just fine?

For C6 yes.
For C10 Mostly yes... but usually class 10 is not really faster... so save the money.
Just my two cents.
I'm using Transcend 8GB class 6 without any problem. Try to format by gparted or similiar. Are you using it for any other purpose than storing photos, music or etc? For example for data2sd or apps2sd?
I just bought a transcend 16gb class 6, working perfectly so far with no problems.

I bought a 16gb class 6 to use with data2sd but struggled as the card was broken - so i've sent it back and just have the 8gb class 2 that i got with my phone now - and on stock rom again, so it is just photos and music and froyo app2sd at the moment
basically all branded cards will work fine, the thing you shoud be concerned more onthe capacity you are gonna use. It aint worth buying a 16GB sd when u cant fill even half of it with useful stuff
If speed is your thing then get a class 4 or 6 but I had SD mounted as read only with a class 4 8 gig Kingston SD, so I swooped with a buddy of mine for a class 2 SD from a Nokia n95, no problems since then.

I wanted to let anyone looking for a micro sd about a deal i found. I found a Patriot Memory 16gb micro sdhc class 10 for $39.99 on www.CompUSA.com I think i'm going to order one after reading here on xda that patriot makes a pretty reliable sd card. I haven't ever used a patriot memory product so i only know what guys on here have posted. anyone make sure you check into the company on your own. They have the wintec 32 gb class 10 for $84.99 too!
apparently class10 cards are no good for phones, take a look at this link
yeah you dont want to spend all the money on something that might not work right?
I had read here on xda that the class of the sd card doesn't matter but the size(gb) is what matters with phones. like my SE X10 is only compatible with up to 16gb of external memory. Is that not correct? Can anyone clear this up for me?
X10's are compatible with up to 32gb microSD cards, I've got one in mine.
The size is important as you want to buy an SD card that works for the content that you intend on putting on it. If you have a lot of MP3s and videos, take a lot of pictures and shoot a lot of videos then obviously you are going to want at least a 16gb SD card.
The class does indeed matter. If you have hundreds or thousands of images then a class 2 card would take ages for them to all load in the Gallery. Or if you use App2SD at all a class 2 card wouldn't be able to keep up with the reading and writing and the app would be sluggish.
A class 10 card in my opinion is a bit excessive, I'd personally go for a class 4 or 6.

This is very true. I have a class 2 card and loading thumbnails for artists/albums is painfully slow in mediascape. I would go for a 32 GB if you are a music fan. I have a 1800 songs on my X10 and its already full. Class 4/6 should be good, class 10 is a little excessive.

Just take the card out of the phone. There should be a 'C' printed on the card and there will be a number inside the 'C'. This is the class of your card.
I was using stock 8 GB class 2, I brought Team 16 GB class 10. Difference in performance is noticeable.
I have a class 10 8gb card and it works way better than the stock card.
Just make sure you tweak your read_ahead_kb.. Search for SD card speed improvement or speed increase.
In general, Class 4 or 6 are good enough for the application usage by phone, such HD video and phones.
I tested my Class 4 sd card, it able to transfer ~5.5mb / sec, not bad.
Yes, when price come down, I will get a Class 100 sd card too.
cheers
I'd rather the class 200.
Sent from my X10i using XDA Premium App
Class 10 significantly improves the performance.
Honestly it does not matter if someone is using the SE stock rom...however since I have tried the awesome ROM created by wolfbreak...my apps stored in sd was very sluggish...had to buy a class 10 16 gig to improve the performance...
Just got a 16Gig class 4 card...goto to play with data2sd and see the quadrant!!!!!!

If you get a real kingston class 10 you will get five times the speed of a low spec class 2 generic sd card.

Real Class 10 SD cards work at 10MB/s of data transfer speed.
Class 2=2MB/s
Class 4=4MB/s
Class 6=6MB/s
Class 8=8MB/s
Class 10=10MB/s
The best are as said by others Kingston and Sandisk.
I've a Sandisk class 6 card and i get near 5,5MB/s of data transfer.
Mine is still 8gb, i want to buy another but in Brazil it's very expensive, the taxes are very high.
Got the Wintec Filemate 16gb class 10 for just under $40 at Frys Electronics and it's given me no problems. Used it in my NookColor running tons of apps and music from it without a hitch. Now it's in my X10 and with using the SD Speed Up tools, it helped alot.

Just take it out and look at at.
There will be a letter C with a number in it....that will be the class of the card
I tried this to no avail. Used gparted to partition and format several times.
when using adb, I don't see devices attached, strangely enough. and so expectedely, subsequent commands from above link do not function
when I put the sd card in a pc under linux, I see all the partitions.
when I boot leedroid, card storage is available.
tried a vast amount of hints and solutions, but nothing helped.
During my trials, lost 2gb of sdcard storage...nowhere to find them...
phone is rooted, s-off. a 16GB sd card works like a charm but is getting small
I want to use cm7, as it give me more room for sw. (phone is always full as for many of you!)

Most people has problem with a class 10 sdcard, 16gb or 32gb class 6 and below, no problem.
I had same problem with 16gb class 10 but not with 16gb class 6.
So my recommendation is to get 16 GB Class 6 SD card from a good manufacturer like A-DATA, Kingston, Lexar or SanDisk. It will be fast enough for all operations.

am using 32GB Class2 partitioned and its been working for almost a year now
Seems my remembrance is only right if it comes to some Class 10 SD cards.
I am thinking of getting SanDisk 16GB Mobile Ultra Class 10 UHS-I Micro SD SDHC like that one.
I know I will not reach 10 Class speed but I need to replace my current card and this is the only thing I found from SanDisk.
Can I expect it to perform flawlessly with HTC Desire?

I am using the same card as well, and it works perfectly. With full class 10 speeds as well.
I am using this as well... No problem at all... Getting much faster speed..
Thanks all. The reason I need to change my sd card is because right now I have a Samsung 8GB Class 6 which is fast enough in transfers but slow in initialisation and newer ICS/JB roms can't even detect it.
What rom are you using with this card?
has anybody noticed a performance increase while using a UHS-I card compared to class 10 or class 6.
Desire needs sd with high IO because of the low internal memory. Now the question, which cards have higher IO? Class 6 or 10 or UHS-I?
Im using a 16 gb uhs class 10 and no issues at all

Well, I got my own card and indeed it is working perfectly fine.

"Mobile Ultra" is class 6 and "Ultra" is class 10. I don't know if there are any other differences apart from speed.
The link you gave is actually selling an "Ultra", although the title is "Mobile Ultra"
Note, I would never buy an SD card on ebay because of the number of fakes (especially Sandisk apparently)
You can get 16GB "Mobile Ultra" on Amazon for £11.45, ie same price as ebay.
Or a 32GB "Mobile Ultra" on Amazon for £22.99
Or a 32GB "Ultra" on Amazon for £18.54
No, I don't know why the class 10 is cheaper than the class 6. However... "class 6" just means that's the minimum guaranteed speed, it might be faster.
NB from what I've read, most class 10 cards don't work on the HTC Desire at all, but some do* However I've also read that internally the Desire can't read at more than 6mb/s whatever you put in there.
*People seem to have success with ADATA 16mb class 10, but someone else said their SanDisk 10 worked, whereas others say the same card didn't work. YMMV

BUT from what I've read, the HTC Desire will accept a class 10 card, but only has a class 6 transfer bus, so it can't use it any faster anyway.

Not quite right since all sandisk mobile ultra micro sd cards are UHS-1 class cards fastest cards faster than class 10.
They run at double the frequency in a UHS-1 compatible device.
Will still work in the desire just much slower. I get around class 10 speeds from my 8gb .mobile ultra

That's interesting. It would explain why they're more expensive than the class 10 cards. But if you look at this amazon page, it's listed as class 6, which is confusing.
All this talk about speed and class isn't worth much to any a2sd script.
Class system is about sequential speed I.e writing a large file and you'll get the class speed.
Writing loads of small files and I doubt you'll get your class speed.
Plus the apps on your ext4 partition could well be reading and writing from both you fat32 and ext4 partition on your SD card slowing the whole thing down.

I suppose the hope is that the higher the class the higher the random read/writes as well as sequential speeds.
But the random write performance measured on Tom's Hardware isn't encouraging (November 10, 2011 so not very current unfortunately, but maybe shows that a class 4 SanDisk isn't to be sneered at)
I was using SanDisk class 4 sd card with InsertCoin-1.1.4 Rom. After upgrading sd card to Kingston class 10, it's really improved the performance of the same Rom.

ok mine must be fake then! will buy a sandisk one from ebay(anyone has a good experience buying microsd on ebay.. everyone seems to say they are all fake... even the trusted buyers sell fake ones?)
AFAIK Desire supports only Class 6, so your Class 10 SD will work as 6.
You will achieve Class 10 speeds only copying with USB from PC for example.

I doubt you'd get class 10 even through the USB.
Best way to check SD card speeds is to put it in a card reader and into laptop or PC.
Checking through the HTC desire is useless as speeds can vary.
I've just tested twice with sdcard tester and got 10mbps and 3.7mbps

Yes you get full speed thru usb as it's not using Desire onboard sd controller...
If you're not getting full speed it might be ROM issue for example.
