I started to say "^+1," but then noted that the WD20EARX is also a "green" drive. So, I'll say "^+1, BUT..." You do not want to use a "green" (or "LP") drive as a boot drive. I'd choose this one for data any day (actually, I did choose a pair of "LP" drives in RAID-1 for my data), but I would not choose any of these as a boot drive. Iirc, 2TB drives still don't have quite the reliability of smaller drives. If I didn't use a SSD as a boot drive, I'd use something like a 500GB or 1TB WD Black or a Velociraptor.
