The Seagate ST31000340AS 1TB Barracuda
A sata 7200rpm drive with 32MB cache and 8.5ms seek time and a 5 year warranty.
It's a great drive, really quick and also very quiet which is lovely. This being an OEM box, you don't get any screws or any cables nor instructions though which probably isn't a problem for most people. Do jot down the serial number before installing it though as it's a mare to get to other wise and you'll need it for the warranty.
Amazon ship it in one of those "Ready to Ship" boxes, which means the box they send it to you in is the box of the product.
