I have there class 10 32 GB SDHC cards - one from my old t-bolt the one in my gfs SG II and the one in my note.
I ran a bench on my PNY and sure enough it did not come near class 10.
So I got all three togehter - backed them up - did a full fat 32 format (not quick) on win 7 and tested all three. On the pc and in the note -
PC Via ATTO
Note via antutu
Of the three brands I had Lexar, PNY and Sandisk - all three supposed to be class 10.
Only the lexar - which was sitting in my unused t-bolt - actually ran class 10 posting 13.6 MB/s writes and 22 MB/s reads..
The others not so much - both the Sandisk and PNY barely managed class 6 writes....
makes me happy for having a 32gb lexar class 10 card then
Just got a sandisk uhs-1 32GB not any faster than my class 10. dissapointed again.

that is not true at all - uhs-1 is 50-70 mb/s in uhs-1 supported devices which Samsung has said the note does support.
testing some more - added in samsung class 6 16 gb I got cheap at microcenter on sale.
Ummm. wow. The class 6 samsung runs as fast as any class 10 or uhs-1 I have tested. Faster in fact than everything but the lexar. Just shy of 11 mb/sec writes in my note and 27.1 mb reads - fast enough for hd video recording. I may order a class 10 sammy to see what it can do!
just ran it through Crystal Disk Mark - here is the results - again this is a cheaper class 6 card

Can anyone recommend a similar program for Linux, or even an Android app?
I've tried using dd, with various sync options, but get inconsistent results.
thanks much indeed...

Antutu benchmark has a built in file read/write test.
On antutu my n7000 gets I think 10Mb/sec write and 22MB/sec reads
My 2.5 year old class 6 16GB uSD card gets 4.5MB writes and 14MB reads in the note.
sd tools from the market as well will test your sd card. I do a full format before I test though. Framentation and data can affect your results.

Because it's not true: UHS-1 does not equate to Class 10.
On a device that supports UHS-1, it will be very much faster than Class 10.
On a device that does not support UHS, it won't.

Use CrystalMark, because those speed are irrelevant for custom ROMs. Speeds that are important are with 4K files.
what allocation size , i find with 32 k on my 16gb sandisk class 4 writing speed is higher than read with 32k allocation using sd tools test on phone
With A-DATA 16 GB Class: ~ 7,7 MB/s write and ~ 19,5 MB/s read.

The last result is really interesting. I have a 4 GB class 2 SDHC card from Sandisk and i get 9 MB/s write speed and 24 MB/s read speed; tested on my PC with the built-in card reader. I have tested two other SDHC cards, both Sandisk, one class 4 one class 6, with the same PC & reader, and they don't go over 5 MB/s (write speed) under the same testing conditions - copying a 700 MB file from the PC to the SD. Weird or what?
P.S. - All cards were fromatted under Windows 7, default allocation size.
@TVTV
I know, it's weird. Surely with a class 2 card I shouldn't be getting those kind of results???

Can't comment on that card but did get a Samsung 16GB class 10 and then found out (after I'd ordered it) that class 4 are the best for phones as you tend to be writing mixed content. Apparently the c10 cards are not optimised for this and can be slower than c4. I can say that I recently connected my Note as a USB device to write a 2.5GB video to my SD card and got over 10MB/sec so am very happy to have gone for the c10 version.

/sdcard/ is not external sdcard for SG Note. It is /sdcard/external_sd. As proof, check its size is not 16 GB (14053 MB) but more 12 GB (11168 MB) that is equal to the 16 GB of the phone minus memory allocated to the system.

Careful! I have ordered one of these (Lexar 32GB Class 10) from Amazon. At first it worked fine but after a few days the phone started showing "SD Card Damaged" and it wouldn't access it at all. Formatting didn't help. Yet, it would work just fine in an USB adapter in a PC...
The weirdest thing is that the EXACT same thing happened with my second Note (I returned the first one to Expansys and got one from Amazon.de £70 cheaper . No comprendo.
(When I checked kernel logs (dmesg) on the Note, there was a problem right on the block layer... It couldn't read the raw device (sdc))
Exactly the same problem with the Lexar 32GB Class 10 for me as well in both the GNote and GS2. Never had a problem with any form of SD card in the past. RMA'd the Lexar and will probably try a Samsung Class 10 next.

There is no real advantage of class 10 over class 4 in a mobile phone, where random read write is the key thing.
However I have seen good class 10 cards with good random read write speeds.
See towards the last few pages of the above thread.
If u can find the random read write of samsung class 10 , it would be great to know.
I used to have a patriotic class 10 signature 16gb card that jus died. Apparently, I took advantage too many times of just unplugging with out disconnecting first. Stupid self.
Now I would like to replace it but I don't necessarily want the same card I feel the class 10 was performing more like class 8 or below on my Epic Touch.
Does anyone have a class 10 16gb that perform top notch on their epic touch?
I also curious does deleting a picture causes a stop in playing music for everyone else with their epic touch. I just can't recall this ever happening on my evo before.
Sent from my SPH-D710 using xda premium
Edit : Apparently, I just read some reviews on the patriot sd card and for some reason with Android phones and tablets they sometimes go corrupt and need to be reformatted. There is also an occasional freeze as well. It appears then these cards can't be used right now until they fix this. Just wanted to post this in case others were experiencing issues with their patriot sd card
I've heard great things about these http://www.amazon.com/gp/product/B0058GH4U0/ref=ox_ya_os_product
They were sold out for a whole month so it's possible they may sell out again. Check out the reviews

SanDisk is the best. I been using this one for over a year between 2 phones and never a problem. Class 4 but plenty fast.

$30 at Amazon < NEW 32GB
SanDisk 16GB Class 4 for $8 is refurb (I would rather go new, but it may be fine)
I have many SanDisk cards and they routinely test as double their stated class. (Class 4 card tests as class 8). I have some cards that are stated as clas 10 and routinely test at under their stated class (Class 10 card tests as class 6)
So I would not put too much stock in their stated ratings.
Buy SanDisk, you will not be disappointed.
If you need one that says Class 10 on it, try this one from Samsung:
http://www.amazon.com/Samsung-MicroSDHC-Memory-Komputerbay-adaptor/dp/B00698ZUHK/ref=pd_cp_e_3
Microcenter sales them for 25 bucks. They have their own brand. I believe it I'd made by Kingston. I have been using out for 4 months and had no issues.
On my Epic mobile phone.
You really don't need to spend the extra money on a class 10 card for your phone.

Very true !
I got the Silicon Power 32GB Class 4 microSD. Haven't had a problem with it, was cheap (AUD $44) but is quite slow (about 2-3MB/s) which is expected from a Class 4 card.
Btw class 10 won't make huge difference in ur phone compared to class 4 but when copying to pc its a massive difference

My Lexar Class 10 is, as expected, twice as quick at transferring files as my old Sandisk class 4.
I'm wanting to get a new memory card, preferably 32gb but I'm unsure which company to go for.
So it'll be helpful if you could benchmark your own memory cards with SDTools and also include class and manufacturer ( I find that different benchmark apps produce different results)
Without SD-Booster (Which btw is very effective)
Currently mine is a Samsung 16GB Micro SDHC Card - Class 10
