WD Ultrastar DC HC580 22TB SATA Data Center Hard Drive with Improved OptiNAND Technology, ArmorCache Power Loss Protection, Energy-Assisted Magnetic Recording, Triple-Stage Actuator, and 10-Disk CMR Platform for Maximum-Density Enterprise Storage
The Western Digital Ultrastar DC HC580 WUH722422AL5201 (0F62790) is a 22TB enterprise SATA hard drive that delivers 7200 RPM performance with improved OptiNAND technology, ArmorCache power loss protection, Energy-Assisted Magnetic Recording (EAMR), and a Triple-Stage Actuator (TSA) on a 10-disk CMR platform achieving 2.4TB per platter in a standard 3.5-inch form factor. The HC580 integrates an iNAND Universal Flash Storage embedded flash drive with spinning disk media to offload metadata to flash, enabling higher tracks per inch and greater areal density while maintaining the Conventional Magnetic Recording format that enterprise workloads require, and the ArmorCache feature ensures all data in the DRAM cache is safely written to the onboard non-volatile memory device during a sudden power loss event, delivering enterprise power loss protection in both write cache enabled and write cache disabled modes.
The SATA interface provides broad compatibility with server, NAS, JBOD, and NVR storage platforms running Windows, Linux, or Windows Server, and the 512e disk format ensures drop-in compatibility with existing SATA storage controllers. The 22TB capacity on the 10-disk HelioSeal platform with 2.4TB per platter delivers one of the highest density points available in the Ultrastar SATA lineup, the 550TB per year workload rating handles sustained mixed read/write operations in 24/7 data center environments, and the projected 2.5 million hour MTBF provides the reliability that enterprise storage deployments require. The 5-year limited warranty supports long-term procurement planning for large fleet deployments.
Where the WD Ultrastar DC HC580 22TB SATA Fits
- Data center and cloud storage tiers using SATA infrastructure where the 22TB capacity on a 10-disk CMR platform maximizes terabytes per drive bay to reduce rack space, power, and cooling costs, the improved OptiNAND technology enables capacity gains through flash-enhanced firmware without requiring a platform change, and the ArmorCache feature provides enterprise power loss protection without requiring write cache disabled mode for data safety
- High-capacity NAS, NVR, and surveillance storage where the 22TB per bay provides maximum recording time for video surveillance or maximum file storage for NAS environments, the CMR recording format delivers consistent write performance without the rewrite penalties of shingled recording, and the HelioSeal helium technology maintains lower power consumption and operating temperature in always-on enclosures
- Enterprise archive, backup, and bulk storage platforms where the 22TB capacity per bay directly reduces the total drive count needed per petabyte of raw storage, the 550TB per year workload rating and 2.5 million hour MTBF handle sustained 24/7 enterprise workloads, and the EAMR and TSA technologies provide enterprise-grade areal density and head positioning accuracy for consistent performance in dense multi-drive enclosures
