WD Ultrastar DC HC570 22TB Data Center Hard Drive (0F48155) – SATA 6Gb/s, 7200 RPM, 512MB Cache, CMR

The WD Ultrastar DC HC570 22TB (0F48155) is a 3.5-inch enterprise data center hard drive for servers, cloud storage and high-capacity arrays. With 7200 RPM operation, SATA 6Gb/s connectivity and a 550TB/year workload rating, it suits IT teams, integrators and resellers deploying always-on capacity.

Enterprise-grade capacity for servers that run nonstop.

Built for the Duty Cycle of Modern Data Centers

Data center drives run nonstop in dense racks, sharing vibration, heat and constant I/O with dozens of neighbours. Consumer and NAS-class drives are not rated for that environment, and failures there cost rebuild time, performance and service levels.

The WD Ultrastar DC HC570 22TB is engineered for enterprise duty with a 550TB/year workload rating and HelioSeal helium technology for lower power and heat. At 22TB per drive, it delivers some of the highest capacity per bay available, so data center pools reach large usable sizes with fewer drives and less power per terabyte. The SATA 6Gb/s interface is backward compatible with SATA 3Gb/s ports and works with standard SATA controllers, NAS bays and server backplanes.

Capacity and Efficiency per Rack Unit

At 22TB, the drive helps consolidate storage into fewer bays, reducing power, cooling and chassis count for the same usable capacity.

Enterprise Reliability for Continuous Operation

Rated for 24/7 workloads with enterprise MTBF figures and RAID-tuned error recovery, it gives IT teams predictable lifecycle planning.

Setup Instructions

How to Deploy the WD Ultrastar DC HC570 22TB

1. Confirm your server, JBOD or array supports 3.5-inch SATA 6Gb/s drives at this capacity.
2. Install the drive in the correct OEM carrier or tray.
3. Hot-insert into the bay (if supported) and verify detection in the controller or HBA.
4. Add it to a RAID set, ZFS pool or storage cluster and enable S.M.A.R.T. monitoring.
