Toshiba Class 2, 16GB:



Lexar Class 10, 32GB:



Not convinced that either of these are actually class 10, although SdTools isn't particularly reliable/consistent anyway..

EDIT: Oops, the 16gb PNY is the one in my camera. The first one is actually a Toshiba Class 2, 16GB

Weird, I have the same card and get a lower write speed...

What's the speed of yours when copying files over USB? I get like 5MB/s max. I wonder if mine is faulty.
I have the same card also. My readings are very strange with SD Tools. I can run it and get as low as 4MB/s read and 18MB/s write. When I run the test again immediately it can go as high as 9.7MB/s read and 36MB/s write. I can keep doing it over and over and every time is a different reading. I've tried to do this after rebooting, I've tried it on different roms (AOSP and Sense) and still the same thing. I've tried SD Booster and it didn't help much either.

so it seems that the results of this app maybe not reliable, or there is another something that affect on the results.
Anyway it does not appear to benefit from this test.
thnx very much :)

Can't you people see that it does not matter which class you have. Because Dhd can't write faster than 5–9 mbs even if you have class 10.
So put whichever you like to use you will get the same speed. I have both a class 2 and a class 10 and I get theI same result.

I don't know if it's reliable or not, but I did 3 tests on my DHD, AR 6.3.1 mod, quite a few apps installed, half-full SD card a KINGMAX 16GB Class 6 which i bought 2 days ago. My previous card was a SAMSUNG 8GB Class 2 (the one that came with the phone).

What's interesting to note is that, after doing the first test I thought to myself "hey, why not overclock the cpu from 1.1GHz to 1.6GHz?" and so the second test went better than expected. Then I went from 1.6GHz to 1.2GHz and I got slightly better results than the 1.1GHz. See for yourself:

1.1:


1.6:


1.2:




Coincidence much? Or working as intended?

Notes: Both cards are SDHC. OC has been done with Daemon Controller. 1.1=1152000. 1.2=122880. 1.6=1612800.

Even without over clocking you will get a different result every time u run the test, even if u do it back to back. I think the test is full of **** and shouldn't be relied on.

Sd tools?

I'm extremely dubious about the results obtained from SD tools. I recently bought a 16GB, class 10 Samsung card and got to testing it. I got almost identical results for the 16GB card as I did for the 8GB, class 2 card that came with phone, but I did notice a difference in the time each card took to complete the test so I timed them.
8GB Class class 2: write 87 seconds, read 27seconds.
16GB Class 10: write 51 seconds, read 7 seconds.
So going by time took the class 10 is a lot faster but not according to the figures from SD tool results. Maybe someone else could try and post their results. I know this is off topic but if SDtools doesn't give accurate results none of these posts are any good.
