I've built a new Vista 64 system. Most of the hardware is new and fairly quick. I decided to reuse my old WD Raptors (2 x 74GB). When I run the Windows Experience Index test my system scores pretty well (5.9 for most categories) but only 5.6 for the disk category. This is a bit surprising as i'm using Raptors which are supposed to be fairly quick.
Here is a screenshot of the WEI result:
I've done a couple of disk improvement recommendations (turn off 8.3 filename generation in the Registry and disable indexing). Is a score of 5.6 the most i'll get with these Raptors and Vista 64? There are no unidentified bits of hardware as far as Vista 64 is concerned and I think I am using the latest drivers for everything.
