HGST Ultrastar DC HC570 22TB SAS Data Center Hard Drive with HelioSeal Helium Technology, 12Gb/s SAS Interface, 7200 RPM, 512 MB Buffer, and 5-Year Warranty for Maximum-Density Enterprise Storage
The Western Digital HGST Ultrastar DC HC570 WUH722222AL5204 (0F48052) is a 22TB helium-filled enterprise SAS hard drive that delivers 7200 RPM performance, 512 MB buffer, and 12Gb/s SAS connectivity in a standard 3.5-inch form factor for 24/7 data center environments. The HC570 builds on Western Digital's Ultrastar helium platform to deliver 22TB per drive bay, providing one of the highest capacity points available in the enterprise HDD lineup for organizations focused on maximizing storage density and reducing total cost of ownership per terabyte.
The 22TB capacity addresses the storage density requirements of hyperscale cloud, enterprise archive, and content delivery environments where maximizing terabytes per rack unit directly reduces infrastructure and operating costs. The 12Gb/s SAS interface provides dual-port connectivity for multipath I/O in high-availability storage architectures, while the 512e/4Kn disk format ensures compatibility with both legacy and modern enterprise storage controllers. The helium-sealed environment delivers lower power consumption and operating temperature per terabyte than air-filled drives, and the 5-year limited warranty supports long-term procurement planning for large fleet deployments.
Where the HGST Ultrastar DC HC570 22TB Fits
- Hyperscale cloud and data center environments maximizing storage density where the 22TB capacity delivers maximum terabytes per drive bay to minimize rack space, power, and cooling costs, the helium-sealed environment reduces power consumption per terabyte compared to air-filled enterprise drives, and the 7200 RPM spindle with 512 MB buffer handles sustained enterprise read/write workloads
- High-availability SAN and JBOD storage arrays where the 12Gb/s SAS interface supports dual-port multipath I/O for controller failover without data path interruption, the 512e/4Kn disk format provides compatibility with enterprise RAID controllers and storage platforms, and the 5-year warranty supports long hardware refresh cycles in enterprise procurement
- Enterprise archive, cold storage, and content delivery platforms where the 22TB capacity per bay reduces the total drive count needed per petabyte of raw storage, the helium technology maintains consistent performance across temperature and vibration conditions in dense enclosures, and the Ultrastar DC platform enables rapid qualification into existing data center infrastructure
