Western Digital has launched new 7200 RPM 2TB hard drives and said that it is qualifying with OEMs enterprise-class hard drives on its 500 gigabytes-per-platter technology.
The company said that the family of WD Caviar Black drives, led by the new 2TB capacity, is suitable for gaming, high-performance desktop systems and workstations; while the RE4 2 TB is suited for servers, network attached storage and storage networks.
According to Western Digital, the Caviar Black and RE4 2TB drives combine 7200RPM spin speed, 64MB cache, dual stage actuator technology, SATA 3 gigabits per second (Gb/s) interface, and an integrated dual processor to deliver performance in a maximum-capacity drive.
WD Caviar Black 2TB and WD RE4 2TB hard drives features include IntelliSeek, which calculates optimum seek speeds to lower power consumption, noise and vibration; StableTrac motor shaft secured at both ends to reduce system-induced vibration and stabilise platters for accurate tracking, during read and write operations; and NoTouch ramp load technology.
The company said that the head positioning system with two actuators is expected to improve positional accuracy over the data track. The primary actuator will provide coarse displacement using conventional electromagnetic actuator principles and the secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
The WD RE4 drives also feature 1.2 million hours MTBF, Active Power Save, enhanced RAFF technology, multi-axis shock sensor, native command queuing, pressure sensors, third generation dynamic fly height and time limited error recovery (TLER).
Tom McDorman, vice president and general manager of enterprise storage solutions for WD, said: Specifically designed for enterprise-class applications, WD’s RE4 2TB drives incorporate the best combination of features, optimum performance, and superior reliability that customers have come to expect from WD. Our enterprise products are directly aimed at customers who require additional features and extensive testing that are necessary for high-end enterprise environments.
