Recommended Posts

Just found this app on the market. It's called "SD Card Speed Tester". Tests Read and Write speed of the SD card.

http://www.androlib.com/android.applicatio...4ward-Fmtw.aspx

Here are my results:

Write speed: 6 MB/s

Read Speed: 14 MB/s

My Card: 8GB PQI MicroSD Class 6.

OS: MoDaCo Custom ROM - Stock T-Mobile Style 1.7 / A2SD Enabled.

NOTE: End all running apps for better results :rolleyes:

4mb write

13mb read

Class 4~6 unknown

(Speed flux.. Maybe that some apps were interfering)

Not bad for a £5 4gb play.com micro sd :rolleyes:

Class 4 - the one that came with the pulse :rolleyes: still haven't gotten around to buying a 8gb class 6..... may be with my next phone (in around 5-10 years :D :( )

Interesting ... my 16MB "class2" sandisk card form amazon comes out as 5mB/s write and 15MB/s read and s thus classified as class 4!

6MB/s write.

14MB/s read.

8GB Transcend Class 6

MCR 1.8 vanilla.

When I first got my card I tested it in my card reader (to check if it was fake) and recall it managed more like 12MB/s write and 20MB/s read. I suspect we are seeing the limits of the Pulse in these benchmarks.

It really seems so. But then it's not worth buying class6 cards for it, because class4 cards reach the same speeds in the Pulse.

We also don't know much about this utility - what sizes of file it is trying to write etc and the sequential/random nature of the operations.

"Your SD card needs at least 200MB free space to run the test" I guess it's in the 200mb range. Also A2SD and running apps should affect the speed. And maybe even the OS.

2/4 the first time. 3/5 the second... and in card reader a lot faster. There is definetly some interaction - also I copied some stuff over last night - and it came down to 12mb/sec. So something is strange. All those numbers don't add up.

Might be related to 2.1, also I have a2sd+ and JIT enabled, also there was only 340 mb left on the card when I ran the test. I have an Adata 8gb class 6 card.

ROM: MCR 1.8 Beta 2

Write Speed: 3 MB/s

Read Speed: 4 MB/s

pulse mini stock tmo mk rom, 2gb card that came with phone

7 tests overall: 6tests = 6MB/s write 12MB/s read, 1 test = 5MB/s write 12MB/s read.

3 runs on the same card, which I think is a samsung class 4.

1st run

Write: 4 MB/s

Read: 11 MB/s

Class 4

2nd Run

Write: 5 MB/s

Read: 11 MB/s

Class 4

2rd Run

Write: 6 MB/s

Read: 11 MB/s

Class 6

So something seems a bit odd with the write tests (and hence the class determination(

I guess that apps2sd is messing with the results.
