HGST Ultrastar DC HC570 22TB SATA Data Center Hard Drive with Conventional Magnetic Recording, HelioSeal Helium Technology, SATA/600 Interface, 7200 RPM, and 512 MB Buffer for High-Capacity SATA Storage
The Western Digital HGST Ultrastar DC HC570 WUH722222ALE6L1 (0F48154) is a 22TB helium-filled enterprise SATA hard drive that delivers 7200 RPM performance, 512 MB buffer, and Conventional Magnetic Recording (CMR) technology in a standard 3.5-inch form factor for 24/7 data center and storage environments. The HC570 uses Western Digital's HelioSeal helium technology to achieve 22TB per drive bay while reducing power consumption and operating temperature, and the CMR recording method provides consistent write performance without the write-amplification and rewrite penalties associated with shingled recording architectures.
The SATA/600 interface provides broad compatibility with server, NAS, JBOD, and NVR storage platforms, making the HC570 SATA variant the choice for environments where dual-port SAS connectivity is not required but maximum capacity per drive bay is. The 22TB capacity delivers the highest density available in the Ultrastar SATA lineup at the time of release, and the 512e disk format ensures compatibility with existing SATA storage controllers and operating systems. The helium-sealed environment delivers lower power consumption per terabyte than air-filled enterprise drives, reducing operating costs in always-on enclosures.
Where the HGST Ultrastar DC HC570 22TB SATA Fits
- Data center and cloud storage tiers using SATA infrastructure where the 22TB capacity maximizes terabytes per drive bay to reduce rack space, power, and cooling costs, the SATA/600 interface provides drop-in compatibility with existing SATA backplanes and controllers, and the CMR recording delivers consistent write performance for mixed enterprise workloads
- 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 helium-sealed environment maintains lower power consumption and operating temperature in always-on enclosures, and the 512e disk format ensures broad compatibility with storage platforms
- 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 7200 RPM spindle with 512 MB buffer handles sustained read/write operations, and the Ultrastar DC platform enables rapid qualification into existing data center infrastructure
