Just got a new Power Mac G5 (1.8GHz June 2004) model. Wondering what to do about a new hard disk... I'm not expecting this computer to be lightning quick, it's nearly 7 years old, but I don't want a hard drive so slow that it becomes a constant bottleneck. I also need a decent amount of storage, 1TB at least, even more would be nice, though I'd settle for a faster 1TB drive now and think about adding a slower larger hard drive for media later (I already have 500GB of music in iTunes.) I've found the Western Digital Caviar Green Series (2TB, ~5,400 rpm, 64MB cache, 3 year warranty) for sales for AU$100. Just wondering if anybody has any experience with this drive or has any recommendations. Also found a 1TB Seagate Barracuda 7200.11 7,200 rpm drive for $80, though the reviews I've seen actually seem to indicate it being slower than the Caviar Green. Quick question: got a June 2004 Power Mac G5 which uses the SATA II standard for connecting hard drives. Would a SATA III hard drive (Western Digital Caviar Blue WD10EALX) work in this Mac? Thanks! EDIT: Nevermind, the Power Mac uses SATA I. Can't use the drive. OK, the choice is as below: **** Western Digital Caviar Green, $100, 2TB, ~5,400rpm, 64MB cache and Seagate Barracuda, $80, 1TB, 7,200rpm, 32MB cache **** The price difference is a non-issue. Straigh up I will be using ~600GB of the drive, but I'm unlikely to come close to filling it anytime soon. If the 2TB ~5,400rpm drive is only marginally slower than the 1TB 7,200rpm drive, I'll take the 2TB one, given the fact it has double the capacity. If however there is a significant different in everyday computing tasks I'd go for the 1TB drive and possibly re-asses the situation in a year or so when I have more cash to play with. Again thanks for your help !
