It has around 29.7gb space available (which is about right), tested with h2testw and verified.
But when you get to measure its speed: It cannot even reach 7 mb/s writing speed. I emailed the seller and he agreed to refund 30% of the cost. See the attached image.

Get your credit card company to get a refund for you since the product was not as described.

How fast is it supposed to be writting/reading for a class 10.
Sorry if it's a noob question but I am curious because I intend on buying a bigger memory card. Just wanna know if the class makes a big difference

Class of SD card means the minimum amount of mb per second it can write. Class 10 card should write at least 10 mb per second. Class 6 - at least 6mb per second. And so on.
@ sinbot: They will refund me $7. In this case I bought 32gb Class 6 card for $14 bucks

Is there a program / app to read speed test?

Test this card in computer. Your phone ROM's might has limits.

i doubt it
read http://forum.xda-developers.com/showthread.php?t=1338868
after hundreds of posts showing prove, it's definitely not our phone or ROM that is hitting the limit
our phones can write way over 12+ MB/s
a few Class 10 microSD cards can reach 12+ speeds in our phone

Try not to buy from amazon or eBay. I bought a sandisk 64gb class 10 that looked legit and it was fake.
Always buy from reputable sites such as newegg.com or any recommended suppliers from sandisk site if u want a 64 gb sandisk.
I'm running a team 64 gb class 10 and its running beautifully.

Bought a 32 gb PNY card at Best Buy on sale for $30.00 Class 10 and it's great . Actually got 33.1 gb with it and turned it into my internal storage. Now I have 350 apps and still have over 4 gbs left.

Upgrade SD card

Looking for suggestions. first of all, has anybody filled up the packaged 8gb memory on your phone? and if you've upgraded your SD card, please let me know what kind and how much, I saw a 16gb mircroSDHC from newegg but the reviews were not so great:
*well apparently I cannot post outside links
but here is the item number from newegg.com N82E16820139121
I upgraded to a Winston 16GB Class 10, I got about 4GB's left due to music and movies
Upgraded to a WinTec 16GB class 6 on the first day! It worked awsome!
using the 16gb sandisk that came with my HD2...works fine, (didn't work for crap in the HD2 though). I do not keep a lot of music on it anymore now that I use Slacker almost exclusively...but I do have a couple movies on there at the moment.
I am using the 8GB that came with my MT4G in my HD2 to run Android (works fine as well)
I'm sure you shouldn't have a problem with anything up to a 32gb...just buy from a respectable seller, I have heard a lot of horror stories about cards off ebay
cool, thanks fellas, looks like I'll just go with a 16gb gonna go for a class 10 one.

i'd recommend class 6 since the hardware can barely read as fast as a class 10 card.
but if you wanna spend the extra bucks on wasted speed, go ahead =P
I took the 16gb class 6 sd that came in my Fender mytouch and popped it in. Ive got about about 4.8gb left with music, movies and roms on it. Since there arent any roms that use ext or swap yet, theres really no way to tell how well it functions other then the music and the movies play fine lol

I bought a 32gb memory card class 4 from Adorama for 99.99 with free shipping. Got it and made sure I ran a speed tester on it and it passed. No complaints... however took forever to arrive lol I'm a music junkie and I was about dead by the time I got it because by then I had already sold the one preinstalled.

Just kinda agreeing with agentaaron, my 16gig that came with my hd2 didnt work so well with the hd2 but it loves the mytouch..cant figure it out as I thought it as a defective card...but works just fine.
ok, so I got a 16gb card class 10 for 30 bucks from the egg, can I just copy/paste everything over from my stock card onto the new one and my phone should work just fine but with the extra storage space correct?
yup, thats what I did, no issues so far

1) Copy your whole card to your HDD
2) Download Astro from Market
3) Open Astro, hit Menu, Tools, SD Card Usage
4) Find out what is taking up all the room
5) Use your noggin to delete what YOU think you don't need
6) Remember that you made a backup
Back OT:
I've narrowed down my choices for my new 16GB card to the Wintec Class 10 on Newegg for ~30 or the Komputerbay Class 6 for ~40. Only the reviews so far are making it a tough decision. Will you guys with either card please revisit this thread next week and post your findings after repeated use?
Posting Findings
Got my 16GB Wintec Class 10 in the mail on Friday.
Tested with CrystalDiskMark 64-bit using the prepackaged SD adapter in my laptops SD slot 3 times each.
Sequential Reads 13MB/s+
Sequential Writes 11-12MB/s
I'm impressed. I will continue to use and report back findings.
Going to get my wife one for her MT4G and another one for the Nook Color (X-mas gift) I will be getting.
EDIT:
Tested the stock SanDisk 8GB Class 4 that came with the phone:
Sequential Read : 11 MB/s
Sequential Write: 5.3 MB/s
slightly above the Class 4 rating. Going to keep this card as my 'Movies' card for long trips and such.
Tested my Transcend 8GB Class 6 from my G1:
Sequential Read : 12.5 MB/s
Sequential Write: 6.0 MB/s
Just meeting Class 6 requirements. Will put my daughter's movies on it.

32gb Class 10 Micro SD

Hi,
Had my SGSII for a few weeks now and I've filled my internal SD memory. Was hoping you guys could help me.
I'm in need of a 32gb class 10 micro SD card for all my HD content. Do any of you flash-a-holic's know of anywhere I can purchase one from? I'm sure I'm not the only one wanting upgrade the memory!!!
Cheers
Please click thanks if you found the thread helpful

I have such one from Amazon. It' s from a company I never heard of but works in my SGS II since I unpacked it perfectly and stable. Has lifelong guarantee.
Video rec to sd is nice and smooth and fast, divx videos stored on this class 10 msd play perfect.
Just search in Amazon.....

Don't think a class 10 is as fast as you think it should be, I have a samsung 8gb class 6 that will probably out perform most class 10 cards. Why pay the extra

I have a Sandisk 32gb class 4. It stores 5 MB/s. I have a somewhat unknown 16gb class 6 and it is 15-16 MB/s! So buying cards can be very difficult and rather surprising.

This thread is confusing me all the more. So basically its pot luck! From one SD card to the next speeds can be completely different even same class, same brand ! I guess similar to processors!

I just checked the app, if you do not mount the sd card it tests /mnt/sdcard (the internal memory) but if you do mount the sd card it does test /mnt/sdcard/external_sd. For me the app works.
I think testing on a pc with a card reader is the only way to get comparable results. I don't trust the phones doing a proper job on this. My numbers above are done using H2testw 1.4.
My 32GB class 4 is 9MB/s Write and 14MB/s Read.
I'm quite happy with that.
Here is the result of my Sandisk 32 GB Class 2
What is this program?

Anyone got 32GB microsd class 10 for their Note? If so where did you get it and how is it? I found Samsung ones on Amazon but even though it says that it is class 10 people are claiming that speeds are more like class 2. So, I want to get one but want one that was tried and works. Thanks!

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.

Are you sure /sdcard/ is the path of the external sdcard?

Yes, that's the correct path.

Mujja,
/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.
Hey all in this amazing forum which i was looking for now
I'd like to know which memory i should buy and whoch class cuz i found good deal for samsung 32 gb class 10 and i hope that it's working with full speed with samsung note

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.

SDcard Speed - show us !

Hi everybody !
I'm a new XDA user and i have been reading a lot on this forum and it is very helpful !!
I was wondering if this little beast (wildfire s) is able to take advantage of the different speedclass of the sdhc (class 4/6/10/ even more)
I tought maybe we could start a thread were you guys tell us what is youre sd card (type, model, size) and what is your speed result in Antutu Benchmark
So here is my result :
Kingston MicroSDHC
Class 4
16 GB
Antutu Benchmark :

But I wonder why the write speed is so low in the phone? The controller does not get more out?
Anyone here has any experience with SD Speed ​​Increase App?

Hi,

As info CrystalDiskMark has the 4K QD32 somehow made ​​problems.

thats why i didnt show test made with a card reader , i want to know result with the phone itself !
Have the test done on the phone but only without screenshot. The result can be found below in the post... or again
Antutu Benchmark:
SD card write: 8,7 MB/s
SD card read: 17,0 MB/s
The tests on the PC should only show what the card can. The Wildfire slows down fthe SD card?

Not sure what this does as there is no commonality between ROM's, OC speeds, kernel tweaks, I/O settings, etc, but here you go.
The slowest!

ok , i didnt know it made a huge difference between ROM and settings, like i said , im new in to that ...
in reality i was wondering if that phone would be able to take advantage of cards like this : http://www.sandisk.com/products/mobile1-memory-products/ultra-microsdhc-memory-card
thats why i was asking everybody result depeding on the card they use .... it would give me an idea

Some reading to help out.
It's just hard to gauge.
Switching between noop to bfq i/o scheduling ups my write speed from 5.6 to 11.2 MB/s
It's a little variable. One thing we are seeing here though is things topping out around 17MB/s reading across the board.
Here goes my last Antutu benchmark.
I use a Samsung "Essentials" 16GB Class 6 card now. Used performance, noop for testing.
This one works with Data2SD while my previous Kingston 8GB Class 4 didn't.

Could you please post a screenshot?
IMHO that's a bit high for a class 4 card. I'm not saying that you made these numbers up. It's just a good policy to post screenshots of benchmarks.
Thanks a lot!

SanDisk - Mobile Ultra 64GB microSDXC $49.99 @ Best Buy 1-Day Sale!!

http://www.bestbuy.com/site/SanDisk...4120116&cp=1&lp=1&ref=39&CJPID=3905168&loc=01
If only I could have waited....I just bought a Sammy 32gb Class 10 card for $30 shipped, just $20 and I could have gotten double the storage and a faster card even though this one is just a Class 6. Jump on it guys, this is the best prices I've seen this go for yet!
Just bought two Hopefully can flip the second one to make mine super cheap. Came just in time too, getting a galaxy S3 soon and gonna move my old 16GB into my new nook color.
just ordered mine!!!
How does this compare (other than obviously double the size) to my 32Gb Class 10 Micro SD card? Is this thing faster than my card, even though this new one is a class 6?

I went ahead and ordered this one. I had a $25 Best Buy gift card that I was waiting to use, so with tax this card was only $29!
My current card gets 8.9 MB/s Write and 20.8 MB/s Read. If this new card doesn't match those numbers, I'll just Ebay this thing and make a bit on it and keep my current card. If this new card is faster, it'll pair quite nicely with my 32Gb Blue SG3 that I ordered! Thumbs up to the Op, thanks!
Doesn't look like we even have these in Canada. Boo!

Holy Handicap parking space batman...............
ended up costing me like $34 since I had a gift card floating around from probably a year and half ago. Great Find
DAMNIT! I gotta stay out of this forum. Great deal, but I need to hold off if I can. My uncle works for a company in Cali that makes SD cards. He is sending me a couple 32GB Micro SD's for free. Love to buy this, but a free 32 will do me just fine.
horrible write spd. especially since we're dealing with 64gb it matters much more now. i'll pass

Prove it.
i think its in reference to the class 6, I dont understand it myself but the card boasts up to 30 megs, but then calls itself class 6. Reading on Sandisk's website it says that the "class" rating is "worst case" scenario. The Class 6 seems to be geared for specs on video data while the 30 megs a sec spec talks about picture data.
could anyone clear up the info? ty
The SGS3 supports exFat, the recommended format to get the maximum speeds from these cards.
Other phones using this card were or are formatted as Fat32 which are not the correct format to take full advantage of this cards perks.

that is supposed to be uhs-i capable and the 30mb/s it's advertising is for the read speed. that's just strategy for companies, because they know not everyone sees the * and then reads the fine print for its description.
and as it says in sandisk's website the write speed is slower, that's where the class rating comes in it will write at speeds it is rated.
30mb/s read speed is achievable if the gadget reading the card is also uhs-i compliant.
the class ratings shows that their cards will reach it's class rating's read and write speed.knowing sandisk their speeds usually exceed their class rating's speed. class 6 will read and write at least 6MB/s, class 10 will read and write at least 10MB/s
http://www.sandisk.com/products/mob...crosdhc-and-microsdxc-uhs-i-cards-for-android
according to that only the 4gb is class 6.
8gb and up are all class 10.
btw, op's pic is different from sandisk's website.
this is his:

this is the official sandisk's:
it doesn't have the 1 that is enclosed, which is UHS Speed Class 1 (U1)
I was reading this
http://kb.sandisk.com/app/answers/detail/a_id/1996/kw/class
and it talks about
Rated Speed (e.g. 15MB/s, 30MB/s, etc.) is maximum speed of the card and also what you would expect to approximately see in typical usage of writing or reading files on the card. This measurement is pertinent to still photography, especially for taking pictures with high resolution and/or saving in RAW format where the files created are very large.
and
Speed Class is a minimum speed based on a worst case scenario test. The Speed Class is important for video mode or camcorders, where the device is actually saving a steady stream of data.
It definitely is worded weird, maybe to confuse but it kind of sounds like 30MB/s is what you "could" see under optimal conditions where the device supports such speeds too. But, what do i know.

theres nothing to prove its listed on sandisk website and everywhere amazon
up to 30 mb/s read (reviewers get around 18mb read)
up to 30 mb/s write (reviewers get around 8mbs write)
I got one of these about 1 1/2 months ago when they were on sale, packaging said class 6.
