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.

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 want to max out the memory with a 32gb SDHC. Anyone have any suggestions?
The SanDisk 32GB is very good,
it performs higher than stated with regards to class and obviously is a highly reliable make.

Another vote here for sandisk, havent actually tried their 32GB, but every other card i've had from them has been faultless.
Most important thing w.r.t. memory cards IMO, is to buy from a reliable source. Ebay is rife with fakes.
Arc can handle up to class 6?
Or i shall order a class 8 or 10.
When i bought arc i had in the case a 16gb sdhc card, but i want a faster one
someone was able to get between 6.00 to 6.79 MB/s on his Class 6 16GB MicroSD, but that was on an X10. you might get similar results on the Arc.
(source)
just got a lexar 32gb class 10 card from amazon (solutek) works great , faster than standard card supplied with arc
I guess I'll try the Sandisk, much appreciated guys. Now I just need this phone to be shipped.
I Bought a Sandisk Class 4 32GB and it works fine for me.
The data transfer to the card seems faster when I take it out of the phone.
I was thinking of getting Lexar MicroSDHC 32 GB Class 10 from amazon for my arc so anyone have it already and how is it? cus i didn't see any sandisk microsd have class 10 32Gb.
I've used the original Sandisk MicroSd 8 Gb (Class 2) and a Class 6 variant... When you copy big numbers of mp3 or movies to the phone, it really makes a difference. Example: with a Class 2 it takes about up to 1 or more hours to transfer 1 Gb - a Class 6 does the job in less then 5 minutes...! But if you want to buy a good rated SD because of the HD-camera, then Class 2 should be high enough (according to the experts). Any higher only helps if you transfer data a lot/often (like changing your musiccollection on the Arc).

i'm on 32gb class10 Lexar, so far so good
+1 for The lexar class 10. Very good !!! The best solution with The sandisk class 4.
I bought a Kingstone 16GB Class 4, at first it was impressive but now it jams when shoot a video a lot.

btw, if anyone spots a good micro sd 16gb class 6 or higher please inform me.
I become a 16GB Class 2 Card but this card was wrong, the write speed is 3Mb/s, then I bought a new 16GB Class 10 Card. This card speed: 11.3/20.9 (write/read) the i am happy The maked HD video is better and the frame rate is really 30fps
UPDATE: The card worked much data disappeared from him then until 5 days. The next day the telephone did not see the card already though. F***ing noname card! Nobody let me not buy it trademarkless card!
I'm considering replacing my Sandisk 8GB SD card with a Class 10 32GB one. However, I searched the forum and found a few posts claiming there were compatibility issues of the 32GB Class 10 SD card with Atrix. These posts are a few months old. Does anyone know if it's now safe to buy a Class 10 32GB SD card for use in the Atrix? Thanks in advance!
I've been using a class 10 32gb sd card for a couple of months. Works just fine!

Same here. Lexar32gb sdhc class 10 works just fine ...
Thanks everyone for the response! I'll go ahead and buy a Class 10 microSD card.
I don't think it is necessarily an issue until you use something like webtop2sd. My 32GB class 10 Kingston card works fine until I try to use it to hack up my webtop. The issue at hand is that webtop2sd will not see extfs partitions and cannot create them when this card is involved. However, I put my 16GB class 4 card in and was able to effortlessly execute webtop2sd. Not having the 32GB card that I just bought working kinda burns me up, so I am going to try and use dd to clone the extfs partition from my 16GB card onto my 32GB card. I want the added throughput class 10 has to offer. I just hope that this will work. I will report back with results.

well... I tried and webtop2sd just does not like my 32GB card no matter what. Looks like Ill have to wait for an update or get one known to work.
I use a scandisk 32 GB class 10
works fine
I have a patriot class 32GB class 10 sd card
Also check out SD speed increase or SD Booster to increase the speed of your SD, has mine giving me 20MB/s write speeds and >50MB/s read speeds as bench marked with antutu, up from 12MB/s write and 22MB/s read speed without it. Just have to at least be rooted. Both developed by different people on XDA and available for free in the android market.
Also for webtop with 32GB class 10 SD card I was able to get mine to work using the Full Debian Linux in Webtop mod with the 4GB debian linux on the EXT-SD card. See thread here:
http://forum.xda-developers.com/showthread.php?t=1093790
Had this working on HomeBase Bluechronic 6.2 prior to going over to CM7 Nuetrino GT ROM.
I use webtop2sd on my PNY 32GB class 10, been working fine for me

The class refers to write speed which is great for cameras or if you move a lot of files. Most cards that are rated at class 10 have slow random 4k write speed. When you are running a os on the cards, (webtop) the random 4k write speed seems to be more important than the class speed. SanDisk class 4 and even some class 2 will usually outperform most class 10 cards when they have an OS running on them. There is a good post on another forum on Xda about this, search for Sandisk class 4.

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.
Would putting a swap partition on it decrease its lifespan noticeably?
have someone tried the 32gb class 10 version? does it work well with int2ext+ or m2sd?

"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.

I've just bought a SanDisk class 6 'mobile ultra' 32gb card.
Someone's posted a CDM showing a random write speed of 1.222 (!), so I'm looking forward to seeing the effect from swapping from my current 0.01 speed card!

Just ordered it after reading the rest of the thread, thanks for the idéa!
Planning on getting either a 32gb or 64gb depending on the price.I planned on using app2sd mod to use the micro sd as my main storage instead of the 16gb internal storage. And the micro sd card has to be in FAT32 or EXTFAT format.
1.What the real big difference between class 4 and 10? Beside the price? Is class 10 speed much noticeable or just a minor improvement from class 4?
2.Since i plan on using this as my main storage. Will opening app/games, playing music, viewing video/picture and saving picture on a class 10 be a lot faster than class 4? Also how about coping the files from pc to sd card? Any difference?
3.What brand would you recommend? Is there a difference between a sandisk class 10 and lexar class 10 beside the price?
4.What format do micro sd card come in? If it not FAT32 or EXTFAT, can i change it to FAT32 or EXTFAT?
1. Speed. Class 10 has much faster r/w speeds.
2. Not sure how big a difference itll be. Read speeds should be good enough on either for apps. Its hd video and such that will require higher write speeds though.
3. Dont much care for sandisk oersonally. But I think theyre the only ones offering 64gb. Never tried lexar but Samsung memory has always been the best for me. Jus make sure you trust the seller.
4. FAT32, for most. ExFAT for 64gb. Yes you can reformat.
