Enterprise NAS Hard Drive

The WD Gold WD8005FRYZ is an 8TB 3.5-inch internal hard drive built for enterprise NAS and data-centre workloads. It delivers 7200 RPM performance with a 256MB cache over a SATA 6.0Gb/s interface. This drive targets IT managers and system integrators who need high-capacity, reliable bulk storage for multi-bay arrays.

3.5-Inch SATA Integration

The unit fits standard 3.5-inch drive bays and connects via a native SATA 6.0Gb/s port, requiring no adapter or PCIe slot. Its 26.10mm height, 101.60mm width and 147.00mm length match common hot-swap trays and backplanes. The SATA interface frees up PCIe lanes for other expansion cards in dense server chassis.

8TB Capacity With 2.5M-Hour MTBF

Eight terabytes provide substantial space for archival, backup and media libraries in RAID configurations. The 256MB cache absorbs burst write traffic common in multi-user NAS environments. Workloads that demand sustained throughput beyond SATA limits or capacities above 26TB will need a different storage tier.
