Built For
WD Gold is Western Digital's enterprise HDD line, and the 18TB model is aimed at data centers, servers, network-attached storage, and business RAID arrays that run around the clock. A 550TB-per-year workload rating and up to 2.5 million hours MTBF back it for continuous read-write duty, while Rotational Vibration Safeguard uses dual sensors to counteract the vibration of a densely populated multi-drive enclosure. A 512MB cache keeps large transfers moving, and the drive has been validated across a range of host bus adapters, servers, and enterprise storage platforms.
