From the system in my signature. With Vista 64, this system is rated at the very top (5588) of the Passmark system benchmark scores
... about 800 points higher than the second
Incidently, to get to 7.9 on the disk subscore of Windows 7 WEI required FOUR
3rd generation SSD drives in RAID0:
two SSD: 7.4
three SSD: 7.7
four SSD: 7.9
Also the Atlas SAS drives I'm using for Vista are among the fastest conventional hard drives in the world, and the SAS max throughput (600 MB/s) is twice as fast as SATA II. HDTUNE measures sequential reads of this dual SAS RAID at a very impressive 275 MB/s and 5 ms seek times. Yet it only scores 6.4 on the Windows 7 WEI. In contrast, my four SATA SSD RAID measures about 750 MB/s and 0.2 ms seek times. This pretty much tells me that it's not possible to get into the 7's with conventional hard drives.
