Hey,
i've bought a 16GB class 6 card from memorystar...
If you want to install Link2SD/App2SD a class 6 card will be better (Class 6 is faster...)

I saw a class 10 card smwhere......now is this class 10 faster than class 6?
Sent from my GT540 using XDA App

yes, a class 10 card is faster than a class 6 card, but a class 10 card is very expensive.
Don't buy a noname class 10 card for 30 Euro that might be a fake...

yeah i have that doubt too , about if a 32gb sdcard is properly supported by our phone and not brick it in the trying lol , also how will i know what class if my sdcard? is there a software for check that info?

On the most cards its on the body...
If not you can also ask the shop where you bought the card

A memory card with class 4 or higher is good!

Buy class 6, thats save

Try to avoid buying memory cards on ebay unless you have a clear idea about memory cards and the ebay seller. Some cheap chinese cards on ebay could be fakes which either would not work well or would have the capacity inflated by a driver hack.
microSDs come in class 2, 4, 6, 8 and 10. The speed difference between each of these classes is tremendous. However, the price is also different. Class 10 being most expensive and class 2 being cheapest.
You'd have to strike a good balance between speed, price and capacity. I'd recommend a Class 6 with 16GB capacity.
Of course, if you have lots of money to spare, go for a class 10 32GB.

Which SD Cards are the best ?

I couldn't find a real answer to this anywhere, but I plan on installing CM7 to an SD Card - and boot/run from the card.
Which class of SD card should I be shooting for - and why? Are there any certain brands that work well/don't work well? The same for sizes - is 16GB going to be faster than 32GB ?
Thanks. I'm shooting for a 16 GB internal which should be more than enough space.

Sandisk class 2 or 4

Search this forum and you will find that the Sandisk class 4 disks are great. The best part is they are available at most retail stores, if your impatient. I've been using a 16gb card for a while and it runs stable and smooth.

SanDisk class 4.

SanDisk class 4, 16GB
see the other topics here about sd cards, there are some good known resellers on Amazon who have real SanDisk cards, not the fakes that you can finds for cheaper some places online.

Are there known issues with other brands or faster (eg; class 6 / 10) SD cards on the NC, or is it just when booting the likes of CM7 from them?

Some other cards do have known issues or possibly don't live up to their speed class rating. You might get lucky and get a decent one out of a bunch, but its very hit or miss. Other cards have also been known to die after using them for a bit.
If you're looking for something that is reliable and is consistent, then stick with SanDisk class 4.

I tried A-data 4GB and 8GB class 6, they both run great, tried a generic 16GB class 4, horrible slow. Haven't try any SanDisk yet.

sandisk 8gb class 4 seems to work ok for me
if i went anything larger than 8gb i would want above class 4 speeds i think

Read first post here:

sandisk CL4, 8GB and 16GB seem to be the best bet. faster cards appear to be optimized for speed and large file transfers, but the CL4 and slower cards have better small file read/write speeds.
runnnig CM7 off the card, you want the better small file read/write speeds from the CL4 and slower cards.

Anyone tested any Sandisk Class 6 cards?

Amazon Basics class 10 sdcards work pretty good for me...but i have never run a rom from the actually sd card.
But for $28 (16gb) it actually is class 10-i have all my music and videos and they all perform well. I used to get force closes on my music player back when i had music on internal memory but now that its on external sd i have no force closes
In conclusion the 16gb class 10 amazon basics for $28 has improved my phone satisfaction

This does not hold if you are running off the card. I have a 16GB class 6 Kingston and it runs terribly slow. My class 4 sandisk 16GB runs great.

What monkeymike said.
Pretty much if you get anything but a class 2 or 4 Sandisk(i'd say class 4 for best of both worlds), you run a risk of an unstable system. The benchmark tests seem to put them many orders of magnitude above the higher class cards of other brands.
Plus they seem to be on special just about anywhere i've asked for them. Try radioshack if you are in the US.

I think you'll find that extensive benchmarking of a heap of cards has shown that the ones which are slow to boot are the same ones which have very low 4k random write speeds (as per monkeymike's post reference). The Sandisk 16GB Class 6 cards appear to have decent speeds for 4k random writes, ergo they will be fine to boot from. Other class 6 cards don't perform nearly as well as the Sandisk ones.

I've seen numerous benchmarks around the web showing that the Sandisk class 4's consistently match or beat the class 10's from other manufacturers and I've had great results with them in both my NC and my phones.
That said, its not going to run as well from an SD card (any sd card) as it will when properly installed as the main OS. I know this from experience. I was running CM7 from a generic class 2 for a while and it sucked. Then I got a Sandisk 16gb class 4 and that made a huge difference in usability. But over the weekend I finally took the plunge and actually installed CM7 directly on the NC-and that is a huge improvement over even the best SD card. Still, the Sandisk class 4 is a good way to test the waters.

16GB CLASS 6 vs. 16GB CLASS 10

I have found 16GB CLASS 6 strontium brand which cost around 26USD. You think 16GB class 10 is a big difference for class 6?16GB Class 10 is still not available now in my area. What do you think? Planning to use it on link2sd/app2sd to focus all my apps on SD

Both are fast but class 10 is faster.

I use a transcend 8Gb class 6 SDcard. ofcourse, apps2sd is already included with most Custom ROMs (you do NOT need to move apps to the SD card, a partition,ext3/4, is used as apps and data storage and is treated as internal). Use Link2SD only on the stock ROM.

What i mean is that class 6 enough for day to day operation oe gaminf ie better buy class10?

Class indicates minimum data rate.
6 = 6MB/s
10= 10MB/s
So it is almost 2x faster
Some of "pro" class 10 have speed over 20MB/s

This isn't a huge difference for using app2sd. You can search in web a test of both sdcards. If the price difference is so big, buy the class 6 one.

Guys will our beloved W8/X8 benefit the class 10 speed or it is only for card reader? I mean in terms of gaming. Does class 10 outshines class 6? cause right now Im using a class 2 stock 4GB microsDHC with the write speed of 4.9 MB/s and a read speed of 11.3 MB/s on SD Card tools

You only need a class 10 card if you will be doing 720p video recordings. Since our cellphone can't record in 720p, it is not worth it. If you plan on upgrading your phone soon, then you'd better wait.

i have AData 8GB class 10 card and i pay for it 15$ dollars and worth that money because is very fast and good..

I have AData 16 Gb Class 10 for 28$ and its great =) fast card for good prize.

Class 10 is faster a lot compare with class 6. Because I am always copy files from Office to my laptop everyday, i feel the difference.faster 1.5-3x.
But, our x8 is only run about class 6 speed. So class 10 used on a x8, the speed is only faster about 5-10%.
If you ask my comment, i will still recommend you to buy the class 10,because: it is faster, and the price is not a big difference. maybe few dollars. you still can use the memory card on future phone.

Hmm I had bought a RiData 16GB Microsdhc class 10 worth around 35USD. But when I test with sd tools in market I can get only 9 and if lucky 10.1 most of the time 8.9

Class 10 cards suck at reading a lot of small files (gaming).

but is that normal for class 10? my stock class 2 can go over 3

Help me to choose a Memory card

Hiya guys,
I have been looking forward to buy a memory card of 32 GB. I have found out that there are various memory cards available of different classes. The least one is Class 4 which is the cheapest and Class 10 is the most expensive. I am not sure about the difference between the two.
I would like to know which Class memory card should be fine for the Galaxy Note ? Class 4 will work or I should choose Class 10 memory card ?
Please help me with this...

that would be the read speed.. the higher the better..
most say class 4 is plenty fast for just about everything..some say class 10 would work better if you're trying to watch say a very large video from your sdcard..
personally i think a class 4 or 6 would be enough.

I'm Using Sandisk 32GB Class 4 Memory Card.I Think It Is Best & Enough For My Galaxy Note.

Thanks guys...
I have checked the reviews on Amazon and gone through some of the threads available on this forum. I'm sure Class 4 would work for my requirements. I will choose one..
Thanks again...

I'd recommend the SanDisk MobileMate series, think they're class 4 or 6, good value and excellent stability, as well as speed. Worth a look.

I use class 10 card because they have a better read/write time as an class 4 Card.

Currently using SanDisk 32GB class 4.
The speed is good enough for me.

Lexar 32 GB Class 10. One of the cheapest and fastest.

It's worth reading up on transfer speeds versus read/writes for small files versus larger files. If you're only reading/writing large files then class 10s are what you're looking for.
If you're needing it for installing and rilunning apps or other collections of small files then class 4s will have better performance.
I've also read up that samsung are about to release some new standards with much higher data transfer rates, I'm not sure the note will make full use of them, but they'll be quick transers:

Mine is a Sandisk 32 Gb Class 2, I'm one of the suckers who bought the first time a 32Gb MicroSD got released and payed double the current price..
But it is good enough, I can play large movies up to 3+Gb
**while you're at it, you might want to consider buying 64Gb MicroSDXC instead. http://forum.xda-developers.com/showthread.php?t=1330784

For listening to music or viewing films, classes 4 or 6 are ok (even class 2 from a good manufacturer like SanDisk).
It's when copying large music libraries or films that you appreciate having a class 10 card. And if you intend to use your GN for viewing lots of films, then you'll have to carry copy operations quite often...

The general consensus is that Class 10 is great for what it's intended for: transferring or saving LARGE media files (recording videos or taking high-resolution digital photos).
The lower classes seem to perform better with smaller file transfers.
I have a Class 4 Sandisk 8MB card in my P970, and I'm very happy with the performance. I doubt I'd see a performance increase moving to Class 10.

i have a Class 10 Samsung micro SD-Card with a space of 32GB
The difference between Class 4 and 10 is that C4 has 4MB/s write speed and class 10 10 MB/s write speed.
I would always choose a class 10. they are not so expensive and are more than twice as fast as Class 4

Here's an interesting link comparing different classes:
http://forum.xda-developers.com/showthread.php?t=1150369
I have read that manufacturers have recently improved random read/write speeds on class 10 cards. Dunno. Biggest thing I see is that brand almost matters as much as class. I'd stick with Sandisk.
Enjoy, and good luck.
