If you just bought one they'll ship it in a box that's 8 inches on a side, filled with packing peanuts. Since it's a Seagate drive, it'll be in a static bag that's been wrapped on each axis with bubble wrap.
I wouldn't buy a single drive like that either.
Given how god-awful the AS-series Barracudas are - very hot and very, very slow - I'm not touching 1.5TB drives until Samsung releases one.
Why, does Newegg pack the Samsung drives better?
