Bad SSD Performance of X25-M G2 80GB with AMD SB750, especially at 4k

[derschlambi]

Hi Guys,

I don't know why my SSD performs not very good with my AMD SB750. I am running Windows 7 64 Bit and using AHCI with AMD Catalyst AHCI driver 9.10 and my benchmark results are very bad, especially the 4k Performance which should be good with Intel drives. There was no improvement in changing cables, SATA slots, using Microsoft driver, updating firmware. I don't know whats wrong. I also tried the Intel Toolbox with Microsoft driver and performed TRIM once but no increase in performance. Nearly 50 GB of free space left on the drive.



The benchmarks you see here were taken with a freshly installed Windows 7. Everything I tried had nearly no influence on the performance. 4k values seem very low to me.

Maybe someone can help. Thanks in advance.
