Since using the 240GB OWC Mercury Pro Extreme SSD as my dedicated scratch disk, I've been beating it up pretty good. Being that I'm curious in nature, I wanted to see what kind of speeds it reads/writes. Quick test shows it averaging 253MB/sec. That's fast considering my Apple 256 SSD only writes at 174MB/sec.
But maybe I made a mistake by using the OWC SSD as the scratch disk instead of the boot disk since page files are bigger, badder, and more fragmented and are always on the boot volume?
