So, I bought 2 drives in the past 2 weeks.

1st - a 300g Fujitsu u320 SCSI drive

installed OS and games and seems benches have gone down to:
120mb Max transfer
65mb Min transfer
103mb Burst

2nd - a 300g VelociRaptor

I've seen similar numbers but with a burst of 169mb and min transfer of 77mb

Do the numbers change whether or not info is on the disk like an OS or files etc or does it not matter?
