Hi

I recently bought Sandisk Extreme (SDSSDX-120G-G25) but disappointing the peformance isnt good as is should be.

My motherboard: ASUS P9X79 PRO(

First i connect ssd to Sata 6GB/s port from intel and update firmware to R211. Also i set all options in bios for Sata to AHCI mode.

Then i format it and start some testing. 

Here is some benchmark and other:

Please any help, i have no idea what is wrong.

your performance is normal. as ssd uses uncompressable data. SSD that use sandforce controllers do better with compressable data.
