Great. Wonderful. Don't you just love hard drive failure? Ugh. One of my two primary RAID 0 drives is kicking the bucket. Luckily, I'm still able to get Windows to boot and back up my data, which I'm doing as we speak. I think the HDD error is somewhere the scratch disk uses - after a while of usage the computer just locks, but until then everything functions normally. But that's beside the point. After doing some research, I decided to upgrade from RAID 0 to RAID 5 to preserve high data transfer speeds but to give myself some protection against this in the future. Here's what i'm gonna do: Current: 2x500GB WD Caviar Blue in RAID 0 New setup: 3x750GB WD Caviar Black in RAID 5 So I get to more than double my HDD space while in theory increasing data transfer speeds (by arraying data over 3 disks simultaneously) and increasing protection from the hard drive boogeyman (by allowing fault tolerance on 1 drive at a time). I'd like to add a 4th drive in there, but at $75 each, it starts getting a little pricey. Though now that I think about it, I could probably get either 500GB or 640GB drives for around $50 each. What do you think?
