Hi, I'm a newbie, and I need some help. I want to buy an external hard drive for my Mac that would be able to hold 600-800 of my cds, plus other files like some video and applications to backup my macbook pro since I dont have enough storage space as it is. I think I would need a 500 GB drive, but I'm not entirely sure since all my music files would be in aac format. What I'm most concerned with is the *reliability* factor! I've read on forums and web site reviews where hard drives will be dead in a year's time, and since I'm no expert, I would like to know other people's opinions. I've read good and bad reviews on the Lacie drives, but also for Seagate's drives. Isn't there anything that separates itself from the rest of the pack? I've been thinking of getting the LaCie d2 Quadra External 500GB Hard Drive (4 1/2 mouses out of 5 on MacWorld--but heard terrible things about it elsewhere), Seagate 500 GB one, or even a Western Digital one (isnt' that PC specific?). Anyway, I would like a drive to hold about 500-750 GB. Like I've said, I'm not concerned with much else other than reliability, first and foremost. It doesn't do much good if it's fast and/or looks pretty--BUT STILL fails. I've read about Raid 1 and Raid 5 but it seems I need more than one drive to do achieve that sort of protection. Please help. Any advice will be tremendously appreciated!!!! Thanks.
