Western Digital is shipping their 640 GB 3.5 hard drives. It is the Caviar SE16. The capacity is possible because each platter now holds 320 GB.
The initial suggested price point for the 640 GB hard drive is $139.99 USD. However, just a quick search shows that this hard drive can be bought now for less than that suggested retail price.
