Hi,
I was previously running my M4 in an AMD system. Just moved over to Intel, installed all drivers etc, and I'm very concerned about the performance reduction I seem to have:
AMD:
Seq: 496.94 read, 104.19 write
4k: 23.40 read, 62.11 write
4k-64Thrd: 242.96 read, 95.57 write
Acc. Time: 0.097 read, 0.270 write
Total: 631
Intel:
Seq: 490.62 read, 104.32 write
4k: 24.47 read, 58.71 write
4k-64Thrd: 132.5 read, 77.98 write
Acc. Time: 0.102 read, 0.372 write
Total: 449
Aside from obviously now running on an Intel controller, only difference was firmware version (AMD benchmark was run with 0009 firmware, Intel was run with 000F firmware).
What could be causing the reduction in performance, especially the much poorer 4k-64thrd performance? (I did a secure erase on the drive prior to installing Windows)
EDIT: Read somewhere that C-States could slow it down and should be disabled in the BIOS?
EDIT2: It's not C-States, this makes no difference on or off. as-ssd-bench M4-CT064 M4SSD2 26.10.2011 20-27-37.png 38k .png file as-ssd-bench M4-CT064M4SSD2 06.05.2012 15-39-53.png 38k .png file
