So I have a the newest base model mini and have upgraded the RAM to 4GB but also want to get at faster hard drive? I don't have any specific hard drives to ask your opinion on just that the drive will be 320 GB 7200 rpm. Which brand should I get? Hitachi, Seagate and Fujitsu? I don't want specific links to good deals. I just want to know the best brand hard drives out of these three for my mini. Thanks.
