Your card will only be charged once item ships.
The WD WD RE 2TB 3.5" SATA Internal Hard Drive is a powerful combination of enterprise-class performance and high capacity required for superior performance computing and business-critical environments. The hard drive delivers transfer rates of up to 6 Gbps and high random I/O rates. It is coupled with a dual processor, which provides twice the processing power to maximize performance.
The WD RE SATA Hard Drive's Time-Limited Error Recovery (TLER) feature prevents drive fall-out caused by extended hard drive error-recovery processes. The NoTouch ramp load technology ensures that the recording head never touches the disk media. This allows significantly less wear to the recording head and media as well as enhanced drive protection in transit. In addition, thermal cycling guarantees that each drive is put through an extended burn-in test for reliable operation.
Dynamic fly height technology enables each read-write head's fly height to be adjusted in real-time for optimum reliability. With 64MB cache, the WD RE SATA Hard Drive ensures faster data transactions. It is ideal for use in servers, video surveillance and other demanding write-intensive applications. For RAID-based enterprise surveillance applications, WD RE hard drives deliver cool operation and enhanced reliability features.
