so I can backup my PlayStation 3 and Xbox 360 game saves. I found this one and I want to get the 1 Terabyte Model on Black Friday. I plan on using a Backup External HDD to backup my PS3 and 360 game saves, and backup my iTunes Music Library. Is it possible to save all three things on one HDD? If so, is this a good HDD to do it with? Thanks in advance for any help!
