Western Digital Purple Pro 22 TB

This is a 22000GB 3.5" HDD on the SATA interface. Sequential throughput tops out at 550 MB/s reads and 520 MB/s writes, backed by 512MB of cache. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work. Drop it into the PlanMyPC builder to check compatibility with the rest of your parts.

Warranty coverage follows Western Digital's standard policy — confirm regional terms on the listing. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build. If this drive is not quite the right fit, the category page lists close alternatives at similar prices for a quick side-by-side comparison.
