Western Digital's 200GB "Drivezilla" is about to stomp its way into desktop PCs. The company began shipping the hard drive--part of its new family of Caviar drives ranging from 120GB to 200GB--in small numbers over the past week. The new machine, which spins at 7,200 revolutions per minute, will soon begin appearing at retail stores and online, and will be available in some new desktop PCs later this quarter.

The drive, which the company nicknamed Drivezilla, will give high-end consumer PCs a whopping 80GB more storage than most now have. The majority of top-of-the-line PCs come with 120GB drives, though most manufacturers offer desktop PCs that can fit two 120GB hard drives in order to offer more data storage capacity. Western Digital expects that people who use their PCs to edit and store video and photos, or to perform other multimedia tasks, will want the new drive for its extra capacity. Storing large amounts of video, for example, quickly adds up on a hard drive. Compressed video takes up about 13GB of disk space per hour. Meanwhile, the new drive can also be used by workstations, which are heavy-duty desktops used for tasks such as creating mechanical designs.
