Western Digital RE4 1TB 1000GB Serial ATA II internal hard drive

High-performance technology. With a combination of 64 MB cache, dual processors and dual stage actuation WD RE4 drives deliver lightning-fast performance in demanding server and storage applications.24x7 reliability. Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.WD RE4 enterprise SATA hard drives combine 64 MB cache with dual processors and dual stage actuation for lightning-fast performance in demanding server and storage applications. Technologically advanced acoustics minimize noise. Cool drive operation and enhanced reliability features help protect the drive and the data stored on it.Key Features Massive capacityWD RE4 Enterprise SATA drives are available with up to 2 TB's of cavernous capacity.Dual actuator technologyA 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 model only)Dual processorWith double the processing power, WD RE4 boasts the highest performance of any drive in the WD RE family.StableTracThe motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations.RAFFEnhanced RAFF technology includes sophisticated electronics to monitor the drive and
