Western Digital shipping high-speed 2TB hard drive

WD launches high-performance, 7200rpm, 2TB hard drives for desktop and enterprise environments.

After releasing relatively low-performance 2TB hard drives a few months ago, Western Digital announced Tuesday that it's now shipping high-performance versions of these top-capacity drives.

The new drives are the WD Caviar Black and the WD RE4. According to the company, the former is designed for desktops while the latter is suited for servers and network storage devices.

These two new hard drives are based on WD's 500GB-per-platter technology. They both combine 7200rpm spin speed, 64MB cache, dual-stage actuator technology, SATA 2 (3Gb/s) interface, and an integrated dual processor.

(Dual actuator technology is a head-positioning system with two actuators that improves positional accuracy over the data track. The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.)

Other features of the two drives include:

  • IntelliSeek, a technology that calculates optimum seek speeds to lower power consumption, noise, and vibration.
  • StableTrac, a mechanism that makes sure the motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations.
  • NoTouch, a ramp-load technology that keeps the recording head from ever touching the disk media to significantly reduce the wear and tear of the recording head and media as well as provide better drive protection in transit.

In addition, the WD RE4 2TB enterprise drive features 1.2 million hours mean time between failures (MTBF) and other power-saving, speed-enhancing, and fail-proofing technologies.

The WD Caviar Black 2TB (model WD2001FASS) drive is available now for $299. The WD RE4 2TB (model WD2003FYYS) drive is currently being qualified by OEMs. Both drives are covered by a five-year, limited warranty.
