Whats with these SSD benchmark softwares?

[HURRIC4NE]

I used ATTO and then i also used CrystalDiskMark to benchmark my SSD on a new Z87 motherboard that i brought

ATTO posted speeds above 500mbps for the ssd but CrystalDiskMark surprisingly said i had a 214 seq read and 135 seq write. is the software wrong? i got a nice smile with the ATTO results while a sad face with the other software.

i checked all drivers (updated) made sure of bios settings, and even made sure it had the best port and the wire was not bent as much. but i still got the same results!

Let me guess Corsair Force 3 SSD in sig? Those results are about right for a sandforce ssd using asynchronous NAND.

The performance difference is due to ATTO using completely compressible data and CrystalDiskMark using incompressible data. (You can set CrystalDiskMark to use 0-fill or 1-fill and the results will be similar to ATTO)
