WD Red Pro 8TB SATA drive

This WD Red Pro model WD8003FFBX is an 8TB 3.5-inch internal hard drive built for multi-bay network-attached storage. It spins at 7200 RPM with a 256MB cache and connects through a SATA 6.0Gb/s interface. The drive uses conventional magnetic recording and includes NASware 3.0 technology for NAS optimisation.

Suited for high-capacity NAS workloads

Designed for enterprise NAS enclosures scaling up to 24 bays, the drive supports a 300TB yearly workload rating and undergoes extended reliability testing. Buyers needing flash-like latency or a non-SATA interface should look at a different storage class.

CMR recording and 300TB workload rating

The drive employs CMR technology rather than shingled recording, delivering consistent write performance for RAID arrays. Its 300TB per year workload rating is the specification that determines whether the drive matches the intended NAS duty cycle.
