Western Digital WD80EFPX 8TB 5640 RPM 256MB SATA 3.5" internal hard drive

Designed for NAS workloads

The WD Red Plus WD80EFPX is an 8 TB 3.5-inch desktop hard drive built for small and medium business NAS systems that run 24/7. It spins at 5640 RPM with a 256 MB cache and connects through a SATA 6.0Gb/s interface. NASware firmware is tuned for compatibility across multi-bay enclosures supporting up to eight drives.

Fits standard 3.5-inch drive bays

The drive measures 5.79 in long, 4.00 in wide and 1.03 in high, so it slots into any conventional 3.5-inch bay without adapters. A SATA data cable and SATA power connector from the host system are all that is required. Its 180 TB per year workload rating and power-efficient operation free up thermal and electrical headroom inside a crowded chassis.

Suits RAID-optimised NAS arrays

This drive targets users who need high-capacity, always-on storage for RAID configurations in NAS appliances. It is not intended for portable or single-drive desktop use where lower power draw or faster random access are priorities, nor for environments that demand enterprise-class endurance beyond the specified workload rate.
