WD 7200RPM 2TB desktop hard drives: Caviar Black and RE4

Surely you recall Western Digital's earlier 2TB effort, the Caviar Green -- right? While said drive was just perfect for the casual storage junkie, performance gurus know that it left something to be desired on the speed front. Thankfully, WD is looking out for that crowd too with a new pair of 7200RPM 2TB drives: the Caviar Black (shown left) and RE4 (shown right). Both four-platter drives boast 64MB of cache, a dual stage actuator, 3Gbps SATA interface and an integrated dual processor. The latter also promises 1.2 million hours MTBF, Active Power Save, a multi-axis shock sensor and a few other high-end advancements designed for enterprise users seeking long-term reliability. The pain? Try $299 for the now-available 2TB Caviar Black, while the RE4 awaits an MSRP as it's "being qualified by OEMs." Check the full release just past the break.
