| Features | Cost effective enterprise-class storage Get the right blend of performance, reliability and capacity and optimize your total cost of ownership. 24x7x365 reliability Choose the storage foundation specifically designed for large-scale datacenter replication environments running 24x7x365. High capacity for hyperscale environments Build a massive data footprint with capacities up to 6TB - 216TB per square foot. Designed for quality and reliability Datacenter drives undergo at least 5 million hours of functional testing, and over 20 million hours of comprehensive interoperability testing in an extensive array of server and storage systems. Dynamic fly height technology Each read-write head's fly height is adjusted in real time for optimum reliability. Vibration Protection Enhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over desktop drives. Multi-axis shock sensor Automatically detects the subtlest shock events and compensates to protect the data. RAID-specific, time-limited error recovery (TLER) Reduces drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. 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. Thermal extended burn-in test Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation. Advanced Format (AF) Technology adopted by WD and other drive manufacturers as one of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities. |
