After reading this post on Jeff Atwood's blog, I decided to try one of the Raptor drives. I bought a 74GB drive to use as the primary on a machine that I wanted to repave. I rebuilt the machine and was amazed at the difference it made. Boot time is noticeably faster and software installs went a lot faster than before. I expected some improvement, but didn't think it would be enough to justify the higher price of the Raptor drive. I was wrong - there's a big difference! Based on what I've seen thus...
