I just built a new system with 7100RC--Asus p7p55d Pro, i7 860, 8 gigs, 260GTX and a WD 500 Sata 3G Caviar Black, 32m cache.
I have tried both x86 and x64, basic Win 7 chipset drivers and Intel chipset drivers, used IDE and ACHI and the highest this drive will get is 5.9. The rest of the system shows 7.3. to 7.5
I am not running a RAID, so as the original poster, was wondering why the performance showed as so bad. What is everyone else getting for their hard drives?
It seems I had an older drive connected for a while (not in this current install) which was 1.5 GB/s and it also showed 5.9
Is there a chance something in Windows 7 is looking at something different? The system does seem to operate normally, I see no performance problems except the assessment score.
