I just received a 750GB SATA 7200RPM drive today for 103 bucks. see http://www.geeks.com/details.asp?invtid=WD7500AACS-R&cat=HDD
For your one drive I could have 2 750's vs. your pair of 160GB drives.
Why is your price so far out of line?
I am going to set up RAID 0 with my laptop, since it supports a second hard drive. I am deciding between these setups:
2 160GB hard drives at 5400 RPM for $215
2 100GB hard drives at 7200 RPM for $150 (already own first one)
The good thing about the 160GB option is that I could use the old 100 GB drive for backup, and get an enclosure for it. What's making this decision difficult is the drive speeds. RAID 0 will speed things up, but will 5400 RPM be enough for games like Team Fortress 2? Running Vista Home Premium, too. Greatly appreciate the help, Brian
