WD GREEN = WIN!!

Everything!! Quick, quiet, energy efficient!! Love it!

None... absolutely none!! It's been Brilliant!!

This little drive has been toiling away in my home file server since 2009 with no problems at all. My WD Green army has been flawless!! 2x 500GB, 2x 640GB, 2x 750GB drives have all been running 24/7 since mid 2009 when I built this thing and can't express how happy i am with them. Never had a single WD Green Die on me yet.
