The Western Digital Ultrastar DC HC570 22TB data center hard drive is engineered to meet the escalating demands of modern data centers driven by AI/ML, 5G, IoT, and connected vehicles. Leveraging OptiNAND™ technology, this 22TB HDD achieves an exceptional data density, allowing for up to 22.44PB of raw storage in a standard rack, optimizing space and power efficiency in footprint-constrained environments. As the second-generation platform with OptiNAND, it integrates an iNAND® Universal Flash Storage (UFS) Embedded Flash Drive (EFD) with traditional spinning disk media. This 10-disk CMR (Conventional Magnetic Recording) drive boasts a 2.2TB/disk areal density, maximizing storage efficiency. OptiNAND technology enhances drive resiliency during emergency power-off (EPO) events by flushing critical metadata to the iNAND. The innovative ArmorCache™ feature, enabled by OptiNAND, combines the performance benefits of write cache enabled (WCE) mode with the data protection of write cache disabled (WCD) mode, ensuring data integrity and consistent performance regardless of the cache configuration. Designed for optimal power consumption across various workloads, the DC HC570 offers low power for sequential read/write and mixed random read/write operations. With a projected 2.5M hours MTBF, a 5-year limited warranty, and the capacity to handle workloads up to 550TB per year, this drive delivers the trusted reliability and quality essential for large-scale data storage. Security and encryption options, including Self-Encrypting Drive (SED) models, are also available to safeguard data.
