The primary difference is performance, as far as I know. It's still
considered a consumer-grade drive.
There are some amusing quirks with the Seagate Barracuda (Erp. Not
"green", though the label is. That's probably how I got confused.)
1.5TB drives' firmware. My "head flying hours" are (or were, for a
long time) greater than my "power on hours". Nowhere *near* as bad as
SAMSUNG hard drives and firmware. Next time I consider buying one of
those, please LART me.
