And nice eye, but I can't take credit for it. And I think it's a 2nd edition SM modd'ed to look like a rogue trader.
Not to sound like a broken record but RAID 5, RAID 5, RAID 5.
A Raid 0 is a good boost in performance and runs very well on WD Black drives (they have a larger percent performance gain than the Caviar Blue drives).
However RAID 0 HALF your stability because if either drive fails (corrupt data, mechanical failure, etc) then essentially all data on both is gone. In a RAID 5 you use 3 identical disks (also works very well with WD Blacks) and you get the storage of two of them, about the same performance as a RAID 0 (about 140% the speed of one HDD) but ANY OF THE THREE drives can fail (in any way) and no data is lost - plug in another drive and rebuild the array to re-establish your redundancy.
With a RAID 5 take your three 500GB drives, RAID them and partition it into two 500GB drives (or however you want them divided; 200GB OS partition, 800GB data drive, etc). Now both the data and OS drives have the performance gain, both are redundant, and you'll be one of the only people who owns a RAID 5 (or knows what they are for that matter).
I can't stress data protection/redundancy enough. I've lost a 750GB HDD that had 600GB worth of TV shows on it, and I lost every single one of my 1,500 episodes. Redundancy, Redundancy, Redundancy.
