Western Digital has updated its Black line of hard drives with a new 4TB model that combines fast access times and reliability without compromising the capacity.
Thanks to its fast performance, Western Digital's Black line was always aimed at gaming, high-performance desktop systems as well as workstations, and since it was previously limited to 2TB of capacity, the new model will certainly be extremely popular.
Spec-wise, the new WD Black 4TB spins at 7200RPM, has 64MB of cache, SATA 6Gbps interface and features an integrated dual processor. It also uses what WD calls "dual actuator technology," a new head positioning system that uses two actuators in order to improve positional accuracy over the data track. The primary actuator uses conventional electromagnetic actuator principles for coarse displacement while the secondary one uses piezoelectric motion to fine tune the head positioning resulting in a higher degree of accuracy. It also features IntelliSeek, StableTrac and NoTouch technologies.
The new 4TB WD Black (model WD40001FAEX) is already shipping to select distributors and resellers and has a suggested retail price set at US $339, which is pretty higher than US $179.99 for the 2TB one.
