SSD drive speed

Thought I'd just post a quick review of drive speed after recently upgrading to a new SSD drive. Here are the configurations and speeds:

Two WD 1TB Green drives mirrored (RAID1):
Timing buffered disk reads: 256 MB in 3.05 seconds = 84.06 MB/sec

Two WD 36GB 10k RPM Raptor drives stripped (RAID0):
Timing buffered disk reads: 376 MB in 3.01 seconds = 125.04 MB/sec

OCZ Agility 3 90GB, single drive:
Timing buffered disk reads: 656 MB in 3.00 seconds = 218.45 MB/sec

That is pretty quick. And I think the SSD is limited on this machine as it only has a SATA2 interface which is 3GB/s, as opposed to the SATA3 at 6GB/s.
