It looks like you have an Intel mother board, you should download and install the Intel IRST driver for use in AHCI mode, you'll usually get a bit better performance.

After you do that, go into Device Manager, Disk drives, and find your SSD. Double click the SSD to open its Properties, then click the Policies tab. You'll see "Enable write caching on the device" checked. Uncheck it and click OK. Go right back into the Policies tab, check Enable write caching..., and click OK. A bug in IRST and/or Windows does not really activate write caching until you do these steps, which will improve your scores.

For your SSD:

AS SSD = Worst case test. The toughest test for SandForce based SSDs. Test data used does not match real world data 100%, and is the opposite of ATTO test data.

ATTO = Best case test for any SSD, particularly SandForce, and the benchmark the SSD's specs are taken from. Test data used does not match real world data 100%, and is the opposite of AS SSD test data.

HDTune = Middle area between best and worst case. Test data is ?? of real world data.

How your SSD really performs? HDTune is the closest for your SSD, IMO.

HDTune tests compressible data (at least for write) for the entire drive. For the read test, I believe it just reads the SSD as-is so type of data would be whatever whatever you have written on the SSD (e.g. OS, programs, etc). The dips show the areas of the SSD that contain data while highs show the empty areas.

How do you guys explain that i get roughly sata2 speed with Hdtune (300 MB/s) and sata 3 speed with Atto (400-500 Mb/s) that is what i don't understand.
I understand even less the as-ssd results, the numbers are so low !

Mobo: Asrock 970 pro3
Southbridge: AMD SB950 , see here for more infos
Sata 3(6gb/s) ports

You've got a 64GB SandForce drive. Those numbers are expected. parsec already gave you a very good explanation for each test.

your drive is performing as it should...you can't improve your benches significantly without another drive...
