it looks like that you are using an IDE interface. IF possible, do you ever
think about get a big size external SATA hard drive? It is time for SSD now
. Save money for the new system with SATA interface in the near future.
from my personal experience, SSD easily outperforms my 7200 harddrives,
green power(5400-7200) WD drives, and my Western Digital VelociRaptor 150gb.
I have a OCZ vertex 30gb for windows 7 64 pro. 1tb and 1.5 tb green drives
and my old love velociraptor.
