Running an "external" WD (rubber mount=external?) that I got for $200 a couple of months ago and even though it is mainly my storage drive, I do run movies of it and it has been going great.
I will pick up another one to use to back it up (Raid5?) though it HURTS thinking about that much storage doing nothing.
The fact that I lost a WD500 with all my books & Mp3's makes it a decision I can live with (unsalvageable-ouch!)
