New SanDisk Extreme 120gb and slow performance.


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:

As screens above i tested msahci and iaStorA drivers.

Changed  also cable and switching ports.

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

can you use ATTO disk benchmark and post the results?

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

thanks for being helpful
