I just bought my mac pro, with just the standard 250 gig hard drive. That's plenty of space for me, but I would like to add 1 or 2 10,000 rpm drives for photoshop scratch discs and such. What are some tested, and reliable 10k drives I could look into that would slap right into the macpro drive trays? Speed is my goal, not size. Right now, after 4 years on this old PC, I've got about 100-150 gigs of storage used up. I am not a packrat with music and movies. It just work files (I'm a web developer, graphic artist). But I looooooove speed, so 10k drives are really desired. I have heard that the larger the drive, the faster it will run, but I've never owned a 10k drive before so I am not sure. Thanks for the input.
