Looking to upgrade or build a new PC sometime soon? Check out the very nice guide from Coding Horror: Understanding The Hardware. Very nice look at what to look for and why.
Cool, I didn't know the 300 GB Raptors were out now.
I've been getting the 150 GB Raptors (10,000 RPM SATA) in my dev/tech workstations. Awesome speed, very much worth the $200-$300. Can't wait to try the new 300 GBs.
My home computer (only 19 months old) has a standard 7200 RPM SATA drive but that is so sluggish... grinds a way... will probably upgrade that soon.
