About this item
Overview
The Western Digital DC HC570 (WUH722222AL5204, P/N 0F48052) is a 22TB enterprise-grade SAS 12Gb/s hard drive designed for demanding datacenter and NAS workloads. It features HelioSeal helium-filled technology, triple-stage actuator (TSA) for improved tracking accuracy, and a 2.5 million-hour MTBF rating. This drive is well-suited for high-density storage builds, Unraid arrays, TrueNAS deployments, and enterprise backup targets. It uses 512e sector emulation, so it works as a drop-in replacement in arrays formatted for 512-byte sectors.

Compatibility
This is a SAS drive: it requires a SAS host bus adapter, RAID controller or SAS backplane (LSI/Broadcom, Dell PERC, HPE Smart Array and similar). It will not work on a SATA-only port or in consumer NAS enclosures such as Synology or QNAP without a SAS controller. Fits any 3.5-inch SAS bay in rack servers, tower servers, JBODs and TrueNAS builds. No special drivers or firmware required.
Technical spec sheet
How we test used storage drives
This describes our testing process. Contact us for available unit-specific results before ordering.
- Step 1SMART health review
Reallocated, pending and uncorrectable sector counters read from the drive itself.
- Step 2Extended self-test
The drive's own long self-test, run to completion.
- Step 3Power-on hours cross-check
Hours compared against the drive's internal logs. We never reset counters.
- Step 4Wiped
All previous data is wiped and the wipe is verified.
- Step 5Tamper seal and certificate
Sealed after testing with a numbered tamper-evident seal. Its QR code and the certificate in the box open this exact unit's report.
