Detailed Description

WD Caviar Black drives combine a high performance electronics architecture with a rock solid mechanical  architecture to deliver the perfect storage solution for your fully-loaded PC or maxed out GAMING MACHINE. Cooldrive operation, no-touch head TECHNOLOGY, and leading-edge vibration protection ensure enhanced reliability andsustained data throughput. Dual processor – Twice the processing power to maximize performance. Colossal cache – Bigger, faster cache of up to 64 MB means faster performance. Rock Solid Mechanical Architecture Dual actuator TECHNOLOGY – A head positioning system with two actuators that improves positional accuracy over  the data track(s). 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. (2 TB only) StableTrac – 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 ramp load TECHNOLOGY – The recording head never touches the disk MEDIA ensuring significantly less wear  to the recording head and media as well as better drive protection in transit. Massive Capacity – WD Caviar Black SATA drives are available in capacities up to 2 TB. Compatible – We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab™ and Mobile  Compatibility Lab to give our customers confidence that our drives will WORK in their systems. Compatibility This drive is compatible with any computer/server that accepts 3.5″ SATA hard drives.
