It's model specific. http://www.wdc.com/en/products/Products.asp?DriveID=250
My votes in for the perpendicular Seagates. Slap a pair of those in RAID1 (oh no I lost half my storage space! What a bummer at AU$0.40-50 a gigabyte), and you've got yourself great fastitude. It isn't a word, but it should be, if only for this occasion.
Actually RAID1 is slower because it has to write the same thing to each drive. You gain better reliability. Which is nice for those who don't have NAS or tape or DVDRW or a fireproof safe to keep the hardcode in or and offsite location where you do them and they do you. But if you *do* have all the above it just seems a bit, I don't know, paranoid maybe? :twisted:
