I have a Western Digital 36.7GB Raptor HD, and im out of space. Im down 1GB. So im going to need another harddrive ASAP. As I understand it harddrives dont preform well running that low on space. So my question is, what type of hard drive do I get? Do I get a 300GB ATA Drive at 7200 RPM, do I get a 300GB SATA Drive at 7200 RPM, (they don't have to be 300GB's I just used them as an example), or do I get another WD 36.7GB Drive at 10k RPM and Raid them together?
