My sympathies on your loss.

Have a NAS just for backup. The  drives should last a while since I only turn it on for backups and network rendering.

Now if I could finish that utility that would compare directories and copy over the changed stuff, I would be good to go. Its so tedious to do it by hand.

Check your hard drive temps too, hot drives do not last long.
Have a small dragon doing the 3d graphics in my machine and its just a bit too free with the flames. Had to get disk enclosures that keep the drives cool. Last time I buy/build from scratch.
