this is a class 8 card, anyone been using it for your blackstone, it may increase video playback speed, any1 can provide the bench mark test?

Sandisk Ultra is a class 6 microSD memory based on SD 2.00 Specification.
I just ordered mine through another provider; it should take 2-4 days for delivery.

There is no such speed as a Class 8.
There are three different classes ~ Class 2, 4 & 6.

Can I help?
I have a Transcend 4 GB class 6.
When I use the phone as a USB stick it goes up to 3 - 4 MB/sec writing, a lot of small files about 2 MB/sec.
If y'all want to run some test, just post it, I'll run it.
I've got this from the card benchmark in Pocket Mechanic Professional v2.93.252.
Read: up to 30 MB/sec
Write: up to 4.5 MB/sec
Filesystem operations: 22 ops/sec
Note: large qt of small files will cut these speeds in half, or worse.
Note: I've tweaked the system, file buffers etc.

Micro SD card?

I found this sandisk card that doesn't say a class but has a 10 mb/sec transfer rate. is this fast? http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3267933&CatId=3611
It seems like it's faster than class 6 according to specs...

if you look at the picture, it says that it's a class 2. It's right after where it says SanDisk. It's circled.

Sandisk does not make any cards higher than class 4 according to their website.
There are 8 Megabit (mb) to one MegaByte (MB).
Class speed a minimum data transferred in MB per sec.
There for your 10mb transfer rate equals a minimum class card.
A class 2 card would transfer 16mb per sec minimum.
Class 4 is 32 mb
Class 6 is 48mb
The website does say it offers 10MB of write speed, but um.. thats not possible.
They don't currently make class 10 micro sdcards.
I think their website is wrong.
Remember "For every big B you see, there are 8 smaller ones."
Basic version 1 MB = 8 Mb = 1000 KB = 8000 Kb (the complicated verion is base 8 math and it sux)
This is why when some one says they have a WiFi connection of 5000 Kbps we feel sorry for them.

WTF it double posted, my original post as a sec post?

great, thanks. have you guys tried A-Data cards? I've never heard of the brand, but they have a 4gb class 6 for like 15 bucks

look on newegg. they have a 8 gig transcend class 6 for 18 bucks and free shipping. Better deal and name IMO

http://www.newegg.com/Product/Product.aspx?Item=N82E16820171389
This is the fastest card available right now. Might be more expensive than the Transcend, but nothing beats a class 6 8G SanDisk at this time.

1. Well I guess the Sandisk website was wrong. That's a class 6 Sandisk.
hmmm According to another source Sandisk's Ultra 2 should be getting a minimum read speed of 15 MByte/s.
2. Nothing "Beats" the Sandisk? Based on speed I assume.
A 16gb would tech "beat" a 8gb
So what are you showing for a transfer rate? My Ridata 16gb class 6 is showing 4.65MB write/11.6MB read. I have no doubt that an ultra card would beat that, just curious as to by how much.

"Beat" implies a race. Race implies speed. Since I qualified that statement with "This is the fastest card available right now" you should easily see the correlation. Don't be pedantic.
My SanDisk 8G class 6 card gets about 19 to 20 MB/s read and 13 to 14 MB/s write.

Pedantic?
OK Sure why not.
"Beat" does not imply a "race" ....as a verb it more closely implies a violent, struggle or competition. Hence the confusion.
But that's ok. I knew what you meant. lol
Just asked a rhetorical qualitative question so we could understand your point of reference better.
Nothing personal. No harm intended.

Troll much?
Ooh, look an ignore button, I wonder what it does?

Good to know, thanks. I have a Transcend one as well.. extremely fast.

[Q] Testing the i5800 card speed

Could someone please try "SD Tools" and report you SD cards speeds. Im getting about 2.5 mb/s on both read and write. Tried several cards type 4 and 6. Cards reach full speeds when tested on a PC. Is that a limit for this phone or something is wrong with my unit? I had a Adata SD card die on me recently, too.. Could have been one of the fakes.
So, download and run "SD Tools" program on your i5800 and let me know the results. Also the type of sd card. I cant find any results on internet or this forum. I cant belive that i5800 is capped at 2.5 mb/s.
Thanks in advance everyone!

with the 1GB stock card, I got following result:
2.2 MB write speed
and
4.9 MB read speed.

8GB a-data
3,2 W
6,2 R

Hmm interesting. It seems something is wrong with my phone. I get 2.5 read on genuine 8GB class 4 sandisk card FAT32, at this moment. Thanks! Feel free to add the scores.

is it MB or mB, big difference!

MB/s
Hope "SD tools" can be trusted for Galaxy 3? Guess its time to RMA the phone.

-3.4 MB/s for writing
-4.7 for reading

Ok here is the concluson. I just got a new Class 6 Transcend card to make sure. Phone is OK. I got around 5.5 on both read and write. This is my third card so far.
No1: A-data 8gb Class 6 - died after 3 months of use, was always slow around 2.5 MB/s. I suspect it to be fake!
No2: Sandisk 8gb Class 4 - slow scores like its a Class 2 card. Also 2.5 MB/s. Tested it and its not one of the fake cards. Bought at a big reliable store. It seems Sandisk has some Class 2 cards marked as Class 4. WTF! Hope to return it.
No3: Transcend 8gb Class 6 - finally working as it should! Transfer speeds up to specs. Actually getting close to Class 10 scores with adapter under windows?!
I was either very unlucky or the SD card market is really crazy right now. Im just glad I dont have to return my phone. Thanks everyone for results!

Transcend 8gb Class 6- read=5mb/s
- write-4mb/s

Write = 3.7 MB/s
Read = 17.5 MB/s

Benchmark thread for best sd card for running android

THIS THREAD HAS BEEN CONVERTED TO THE FUNCTION OF RECORDING INFORMATION ABOUT MICROSD CARD BENCHAMARK AND ANDROID ROM PERFORMANCE ON THE SD CARD.FROM NOW ON REPORT YOUR BENCHMARK TOGHETHER WITH THE INFORMATION ABOUT WHICH ROM YOU HAVE INSTALLED AND HOW IT WORK ( LAGS ECC. ) PERSONALLY I SUGGEST TO TRY WITH THIS ONE : http://forum.xda-developers.com/showthread.php?t=954030
1) FOR THE BENCHMARK USE THIS : http://www.hdtune.com/files/hdtune_255.exe TO CHECK ACCESS TIME
2)THEN USE THIS TO AND RUN TEST OF 50 MB AND 500 MB TO CHECK RANDOM READ AND OTHER STUFF : http://crystalmark.info/software/CrystalDiskMark/index-e.html
Also use this app from the market ( it's free ) to improve read speed https://market.android.com/details?id=com.sdincrease.it . Anyway this is about daily use on your android ROM, it doesn't interfere with the test that you can run on your computer !
Original first post :
Hi all !
I was looking for a good memory card to use for booting android from memory card, expecially I was interested in the desire hd build which I know are the slowest one. I hope that a class 10 micro sd with a good access time can solve the speed problem .
I have selected those microsd as I don't want to spend more that 30 euro :

4) http://cgi.ebay.it/ws/eBayISAPI.dll...109247&ssPageName=STRK:MEWAX:IT#ht_4103wt_905
any suggest ?

My advice to you is: check online the benchmarks and tests to SD cards, you don't need a class 10th SD card, it probably will be slower on Android than a class 2, because class 10 SD cards have a huge sequential data speed but a low random write/read, search for random access benchmarks and buy your SD from a reliable seller, carefull with eBay fakes..

Agreed! You may not need Class 10 micro SD as random access speed is much important. Besides, the power consumption of micro SD is also important for running Android on SD. For your info.,
-- normal max. power consumption of KingMax Class 4/6 micro SD is 60mA
-- normal max. power consumption of Toshiba Class 4 micro SD is 80mA
-- normal max. power consumption of Transcend Class 4/6 micro SD is 100mA
-- ......
You can search to find more info. about power consumption of micro SD. As these info. is from official site, which micro SD is the balance between performance and power consumption is required to be tested on HD2.

get the Adata is the best purchase you can do read write 20 mb 16 mb

I see, thanks you all for those advise, anyway I need a 16 gb microsd because now Ihave a 8gb and it's full and I don't know if 16gb class 6 exists !!!
Also my memory is a "team" 8gb class 6 micro sd and I think that it has a bad random access as android never runs well on it...Sadly I don't think that I can find benchmark for those memory card and expecially benchmark of people that are using them to run android.
Also on the productors site there aren't any data on the random access !!

You can use a program called crystalmark to test every aspects of the SD card.. its very good, if you want I can put here my results with my 8gb and 16gb cards..

yeah it would be nice ! Also indicate the brand of the cards !

my "team" micro sd has an access time ov 2.2 ms ...too high !!
I have seen this http://www.androidiani.com/forum/htc-hero/9327-microsd-16gb-classe-6-benchmark.html years better !!

I was just about to do a search on this.
I just want the "best" sd card for a reasonable amount of money (let's say max 200 Euro).
What do you recommend? I don't really need more than 16 GB but I want speed and safety.
What do you think of: Sandisk Sdhc Extreme Pro - 16gb, 45 MB/s?
All input is appreciated!
Cheers,
Patrick

I bought a Patriot 16GB class 10 card, not knowing what I was doing, thinking the faster the better. It was unusable for Android on my HD2. I've used both a Kingston 8GB class 2 and an Adata 16GB class 2 without any issues. Will buy a Kingston 16GB class 4 in the near future. From comments, it seems to be a good card.

not really, kingstone has bad access time from what I have read on the internet..
So your patriot LX 16 gb class 10 is unsuble ? I was thinking to buy just that !!!
Why don't you try to do a hdtune 2.55 test ? it takes 2 minute..so we can see you access time ! ( for the patriot and the a-data ! )

I downloaded hdtune. Don't see a random access time. Here's what I found:
Patriot 16GB Class 10
Transfer time: Minimum 16.5 - Maximum 17.2 - Average 17
Access Time: 0.8 ms
Burst Rate: 14.2 MB/sec
CU Usage: 23.8%
Kingston 8GB Class 2
Transfer time: Minimum 15.6 - Maximum 17.1 - Average 16.6

The issue with the Patriot 16GB card is that I was consistently getting errors after 24-48 hours of use. That has never happened with the other two cards. I can see that the differences between the Kingston 8GB and the Patriot are very small. Obviously, the Adata is less impressive, but 18% on speed and 25% on access time is acceptable if the card is solid. Any suggestions re the Patriot card? Obviously, it was expensive and it would be nice to be able to use it.

well I have write wrong ! I was referring to the access time !! HDtune do not show random access !! By the way your patriot sd is not bad at all also if I have to say that A-data is most impressive because it's a class 2 and has spec of a class 10 !
AH maybe this is your are lucky! I know what's the problem with your patriot SD card, I have read this yesterday.

Do not buy number 1 - Patriot LX class 10. I bought two of them and have terrible results - some androids do not boot at all, constant cash files, error files on the card, often files become unreadable and you can't delete them anymore and have to format the card - not good at all. Now ordered a class 6 card that's 38 dollars more expensive than this Patriot class 10 card

[Q] SD Class and speed

Hello everybody,
So the thing is I want to buy another sdhc for the x5 (8/16 gb) but I want to know which class to buy. With sdtools I have an average of the the following ratings with a Sandisk 4gb class 4:
Writing speed: 9.1 MB/s
reading speed: 19.3 MB/s
1. Does a class 6 or 10 will increase the overall speed (I know 6/10 = minimum speed)?
2. Are micro sd's from brands like Adata or Transcend also reliable in class 6/10?
3. Does the x5 support class 10 and is it necessary or will be a class 6 enough?
Thanks!

Hello everybody,
So the thing is I want to buy another sdhc for the x5 (8/16 gb) but I want to know which class to buy. With sdtools I have an average of the the following ratings with a Sandisc 4gb class 4:
Writing speed: 9.1 MB/s
reading speed: 19.3 MB/s

i find that the class of a card is ambiguous. everything really comes down to personal choice and luck, some cards out perform others while sometimes you'll never hit the minimum write speed that the class indicates. Instead of asking this entire community to make a choice for you out of all the sd cards and their respected manufactures, you should go do some research and come back with, say a top 5
