It looks like Western Digital's hard drives are about to get a good deal denser, with the company now rolling out its first 3.5-inch WD Caviar drives based on 320GB-per-platter technology. That, as the company points out, is the very same areal density seen recently in WD's 160 GB-per-platter 2.5-inch Scorpio drives
, which topped out with a total of 320GB of storage due to the obvious size constraints. While the 3.5-inch drives have plenty more room to grow than their smaller counterparts, Western Digital seems to be starting things out slow, with only a single-platter 320GB drive available at the moment. That'll apparently be followed by upgrades across WD's various product lines throughout the year, including drives at "additional capacity points.," Unfortunately, the company doesn't seem to be ready to specify exactly what those points may be just yet, although The Inquirer speculates that we should see three-platter 1TB drives from the company before everything is all said and done.
