One interesting thing in terms of performance -- hard drives (aside
from WD Raptor drives and virtually any SCSI drive) for desktops run at
7200 RPM. The newer SATA and IDE drives might have a 16M onboard
cache, but in terms of sustained performance data transfer, you are not
likely to see much better performance than an ATA 100 (let alone 133 or
Sata 150) than you already are getting.

About the only place where Sata 300 might show up in real performance
gains if you are running a RAID 5 SATA array with 4 or more drives in
the array -- and that's with an add in controller which includes
onboard cache of its own.
