Western Digital WD Gold 22TB SATA 7200 RPM 512MB 3.5" internal hard drive WD221KRYZ

SKU CH-2T6P-VEE6Q

Enterprise-class 22 TB SATA hard drive with 7200 RPM, 512 MB cache and vibration protection for data-centre workloads

  • 22 TB capacity for massive enterprise datasets
  • 7200 RPM spindle speed delivers fast sequential throughput
  • 512 MB cache accelerates burst read and write operations
  • 5 million hours MTBF supports high-reliability storage environments
  • HelioSeal technology reduces power draw for 12 TB and above

Enterprise storage drive

The Western Digital WD Gold 22TB is a 3.5-inch SATA hard drive built for enterprise-class storage systems and data centres. It spins at 7200 RPM and includes a 512 MB cache to handle demanding workloads with a 2.5M hour MTBF rating.

OptiNAND and HelioSeal

OptiNAND technology on the 22TB model improves performance while HelioSeal technology reduces power draw for capacities of 12TB and above. Vibration protection further enhances reliability in multi-drive environments.

22TB capacity headroom

The drive is rated for workloads up to 220TB per year at 40°C, with derating occurring up to 550TB per year at 60°C. It suits high-capacity archival and nearline storage but is not intended for primary high-IOPS transactional workloads.

商品問答

What maintenance or replacement should I plan for with the 2.5M-hour MTBF rating on this WD Gold drive?

The 2.5M-hour MTBF is a projected figure at 220TB per year and 40°C; above those limits derating occurs up to 550TB per year and 60°C, so plan replacements around your actual workload and temperature.

Which limit appears first under sustained use — the 220TB-per-year workload rating or the 550TB-per-year upper bound?

The 220TB-per-year workload rating is the baseline; sustained writes beyond that level trigger derating of MTBF and AFR up to the 550TB-per-year ceiling.

How much noise, heat and power does the HelioSeal 22TB model produce when running all day?

HelioSeal technology on 12TB-and-above models delivers a low power draw; the drive is rated for continuous operation at up to 60°C device temperature under the 550TB-per-year workload.
