Western Digital Ultrastar DC HC570 22TB - 7200 RPM 512MB SATA III Enterprise HDD - WUH722222ALE6L4 (Bulk)

Meet the demands of explosive data growth with the Western Digital Ultrastar DC HC570 22TB Enterprise HDD. Designed for hyperscale data centers, cloud storage, and large-scale enterprise environments, this high-capacity 3.5-inch drive utilizes advanced Conventional Magnetic Recording (CMR) technology. Operating at a reliable 7200 RPM with a massive 512MB cache and a Serial ATA III 6Gb/s interface, it effortlessly handles intense, continuous workloads while maintaining optimal performance.

At the heart of the Ultrastar DC HC570 is Western Digital's innovative OptiNAND technology, which integrates an embedded iNAND flash drive to offload metadata operations and enhance overall drive efficiency. Coupled with energy-assisted Perpendicular Magnetic Recording (ePMR) and HelioSeal technology, this drive achieves an industry-leading 22TB capacity while keeping power consumption low and mitigating internal air friction. Furthermore, the ArmorCache feature provides ultimate flexibility, offering the performance benefits of Write Cache Enable (WCE) alongside the rigorous data protection of Write Cache Disable (WCD).

Built for the challenging environments of modern server racks, the HC570 is engineered to operate 24/7 with a remarkable Mean Time Between Failures (MTBF) of 2,500,000 hours and a heavy workload rating of up to 550 TB per year. Its built-in rotational vibration safeguard ensures peak performance even in densely packed multi-drive chassis. For IT professionals seeking maximum storage density, efficiency, and steadfast reliability, the WD Ultrastar DC HC570 is the premier foundation for any data-driven infrastructure.
