Useless. Can't use cache.

Good check for the read and write speed of your storage card.

by Matt the 10/14/2010

Seems a little inacurate. Class 8 card got 5.6mb write 9mb read. NAND was 4.7mb and 8.2mb on 8K ?? G2

SD card test yields nonsensical results that mainly reflect buffer size, rather than SD card speed. Uninstalled.

by Rasha the 7/6/2010

Works. Would be nice if the progress box also displayed the current calculated results as the test runs; & ability to save results and review them.

by Ayman the 5/31/2010

Looking for an app that tells me if my SD card is failing so I can replace it before it happens. Guess this isn't what I am looking for.

by Bruno the 5/29/2010

It would be great if it could predict SD memory class. Does android use 8kb buffer normally? I got 5.12MB/s at 8kb buffer.

by Rob P the 5/14/2010

Does what it says on the tin. Select 8kb block size for speediest results in my experience.
