Samsung 830 Series
If CNET's sterling review of the Samsung 830 series solid-state drive isn't convincing enough, here's another incentive.
The company says the deal is available only in the U.S. and Canada and only "while supplies last," so you should make your move as soon as you can. You can buy the drive from any retail store and the key to download and activate the game will be included in the box.
The 830 series is one of the best SSDs on the market and has been on CNET's top 5 list of internal drives for a while. It's one of a few that comes with enough accessories to make it work both with a laptop and a desktop to make upgrading to it an easy job.
