Enterprise storage capacity

The Western Digital Ultrastar DC HC560 0F38785 delivers 20 TB of storage in a 3.5 inch form factor. It connects through a SATA 6.0Gb/s interface and spins at 7200 RPM with a 512 MB cache. The drive is built for enterprise storage environments.

Sustained workload behaviour

The 7200 RPM spindle speed and large cache support continuous read and write operations across the full 20 TB capacity. Enterprise firmware is tuned for consistent throughput during extended duty cycles rather than short bursts. The SATA interface maintains steady data transfer for hyperscale cloud, service provider and surveillance workloads.

Single deciding specification

The 20 TB capacity is the primary factor that determines whether this drive fits the storage plan. Buyers who need less raw capacity per drive should consider lower-capacity models. The 3.5 inch SATA form factor also requires compatible drive bays and backplane connections.
