I'll just quote what Originality said-
QUOTE(Originality @ Aug 28 2011, 09:55 PM) HDD: Stay away from Seagate. For a boot drive, your choice is easy: Samsung Spinpoint F3 1TB, or WD Caviar Black 1TB (or, optionally, a SSD... but that's only if you mind the price of one). For a secondary/storage drive, your choice is still easy: Samsung Spinpoint F4EG 2TB, or WD Caviar Green 2TB.
In explanation, Seagate drives are unreliable and tend to die within a year (from my observations). Samsung and WD have good performance and good prices. For storage, you want an "ecogreen" model because performance isn't important for storage and it'll save energy (and run at lower temperatures) and ultimately last much longer. Win-win.
