HTC Desire Speed Test Result, 20 Jan. 2012
Bought this after a dissapointing verbatim class 10 achieved a maximum 7.5mb/s write speed using h2testw_1.4.
So far the read speeds on the samsung have been excellent and the write speeds have been just above class 10 minimum requirement.
Using SD tools app on android 2.3.3 the card achieved an average of 11mb/s write speed and 28mb/s read, so seems to work nicely in the phone.
When i connected the card direct to my pc and run a 1gb file test on h2testw_1.4 it only achieved a speed of 9.53 mb/s write and 15.7mb/s for read.(please note this card has a hidden 1.5gb ext3 partition not visible in windows, hence only 13916mb available):
Warning: Only 1024 of 13916 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 9.53 MByte/s
Reading speed: 15.7 MByte/s
Using Crystal Disk Mark the following results were achieved:
Settings used 3 passes at 50MB
Sequential Read = 16.34 MB/s Write = 13.18 MB/s
512k random Read = 16.33 MB/s Write = 2.235 MB/s
Random 4kb queue depth 1 Read = 3.308 MB/s Write = 0.022 MB/s
Random 4kb queue depth 32 Read = 3.450 MB/s Write = 0.018 MB/s
When transferring a 350mb video file the card averaged a write speed of 11mb/s.
I think the not so great speed results are probably down to the quality of my card readers.
As the card's primary function is for use in my phone, the most important speeds are those achieved within the device. So although the write speed isn't as high as i'd hoped for, the read speeds are well above the class 10 required minimum.
