I plan on purchasing a Mac Pro soon and had a question on what you guys are doing for storage and what are you using your stock Apple drives for. I'd like to use a 10K RPM drive as a boot drive for OS X and its apps, and then have 2 x 500GB drives setup in a RAID 1 for storage. I planned on purchasing the 500GB drives from somewhere else other than Apple, because they are too expensive. But then I have to purchase a hard drive from Apple when ordering. Should I just downgrade the Apple-ordered drive to a 160GB one to save money and try to sell it on eBay? I guess I just really want to know what others do for hard drives. Thanks for any help.
