How does the Western Digital Caviar Green differ from the competition?
The Caviar Green is similar to the AV-GP in many ways, but features a SATA 6.0Gp/s interface. And at $149, it is the most affordable drive in our round-up. It's $5 less than the AV-GP, and $30 less than the Hitachi Deskstar and Seagate Barracuda XT. But it's worth noting that Hitachi does make a 5400 RPM 3TB drive that retails for $129, which makes it the least expensive on the market--we just didn't have one on hand for testing.
Along with the other drives, the Caviar Green offers you 2.72 TiB of storage after formatting. We didn't expect to see a capacity difference between the drives, but still wanted to verify. As it turns out, every drive we tested provides the same amount of usable space.
