3dGameMan reviews the Western Digital 750GB Hard Drive WD7500AAKS. The WD 750GB HDD starts at $190 on these stores.

Quote from the review: "The Western Digital Caviar SE16 750GB Hard Drive (WD7500AAKS) is one of the largest hard drives currently on the market. Why does anyone need a hard drive this large? Well, if you are asking this question, you probably don't.
On the other hand, if you have or are building a Home Theatre PC you most certainly can use the space. Movies, family videos, pictures, music, TV shows, games and other data require a lot of space. This hard drive performs very well, is quiet and affordable. It's a must have for any serious computer user. Watch the video to find out more and check out the bloopers at the end."
