About one month after Hitachi launched the first 2TB 7200RPM drive, Western Digital has responded with its own entry into the 7200 ultra-high density storage market.

The 2TB Caviar Black features 64MB cache, 3Gbps SATA interface, a dual storage activator and integrated dual processor. Cost for the 2TB Caviar Black is $299 (sure to come down in a few months).

Western Digital has also announced a 2TB RE4 model, to be used in the OEM market.
