Enterprise 22TB SATA HDD

The Western Digital WD221KRYZ is a 22TB 3.5" internal hard drive built for enterprise storage systems and data centres. It spins at 7200 RPM with a 512MB cache and connects through a SATA 6.0Gb/s interface. The drive is rated for up to 2.5M hours MTBF and carries a 5-year limited warranty.

Suited for high-capacity arrays.

This drive fits servers, NAS appliances and RAID arrays that need maximum areal density and sustained write performance. It is not designed for laptop bays, external enclosures or as a primary operating-system drive in a workstation. Buyers who need a smaller physical format or a different interface should consider other options.

22TB capacity on SATA 6.0Gb/s

The single specification that determines fit is the 22TB capacity delivered over a SATA 6.0Gb/s connection. Verify that your controller, backplane and operating system support volumes of this size before installation.
