If you do get this drive, make sure you run a firmware update on it. There's a lengthly article
here about it and a discussion on
Hardforums. Apparently the firmware update doesn't show a new version so it's hard to know whether it's actually installed or not.
With that said, I actually have 4 of these in my NAS for the last 9 months and I haven't had any problems with them. I have to mention that during seek they're a bit noisier than the WD Green's (I had the 1TB WD Green's prior to putting in the Samsung).
