Thanks for the info..... I didn't want to go for the "Green" variant
either but they seemed to be highest in capacity for 2.5" drives which
is why I really had no choice. I prefer WD Black drives as I've had
really good experiences with them. Guess I'll just have to wait till the
capacity of the smaller drives increases :-(
