As a postscript to these tests.. I just tried the 500GB Monentus XT hybrid
SSD/HDD drive. I had this fantasy that it would at least do better than the
7200 rpm desktop drive.
Oh lord, my gut was wrong. The performance was inconsistent and never over
2/3rds the performance of the slowest desktop drive.
