20 TB Enterprise Hard Drive

The Western Digital WD203KRYZ Gold is a 3.5 inch internal hard drive built for enterprise storage systems and data centres. It delivers 20 TB of capacity using CMR recording technology at 7200 RPM with a 512 MB cache. The SATA 6.0 Gb/s interface connects to standard desktop and server backplanes. Designed for continuous operation, it carries a 2.5 million hour MTBF rating.

Suits Heavy Workloads Not Portable Builds

This drive suits small and medium businesses, design professionals and IT managers who need high-capacity, high-reliability storage for mission-critical data and creative output. It is engineered for demanding, continuous read-write workloads in commercial environments. Buyers who need a drive for laptop upgrades, external enclosures or low-power silent operation should look elsewhere. The 3.5 inch form factor and enterprise focus make it unsuitable for those mobile or space-constrained scenarios.

SATA 6.0 Gb/s Interface Decides Compatibility

The single specification that determines fit is the SATA 6.0 Gb/s interface. Your system must provide a standard SATA data and power connection for this 3.5 inch drive. Verify that your motherboard, controller or backplane supports SATA 6.0 Gb/s to utilise the full interface bandwidth. Without a compatible SATA port the drive cannot be installed or used.
