8 TB NAS drive with CMR recording

The WD Red Plus WD80EFZX is an 8 TB desktop internal hard drive built for network-attached storage systems. Its conventional magnetic recording technology and 5640 RPM spindle suit multi-bay NAS enclosures that run continuously. Small-business and home-office users who need dependable bulk storage for backups, media libraries or archiving will find the capacity and firmware tuning appropriate.

Fits 3.5-inch bays with SATA 6.0Gb/s

The drive measures 147.00 mm long, 101.60 mm wide and 26.10 mm high, matching standard 3.5-inch drive trays. A single SATA 6.0Gb/s cable provides both data and power connections, leaving PCIe slots free for other expansion cards. NASware firmware handles error-recovery timing and power-management defaults so the host NAS does not need manual tuning for each disk.

180 TB per year workload rating under 24x7 load

Rated for up to 180 TB of data transferred per year, the drive is engineered for sustained write and read cycles rather than burst workloads. 3D Active Balance Plus dual-plane balancing reduces vibration in multi-drive chassis, helping maintain consistent throughput during long RAID rebuilds or continuous streaming. An MTBF of up to 1 million hours reflects the design target for always-on operation.

Features3D Active Balance Plus
Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.
24x7 Environment
Since your NAS system is always on, a reliable drive is essential. With an MTBF of up to 1 million hours, the WD Red Plus drive is engineered to tackle 24x7 environments.

Questions about this item

Will the 5640 RPM speed become the bottleneck during long write sessions?

The 5640 RPM class and SATA 6.0Gb/s interface set the sustained throughput ceiling, while the 128MB cache absorbs bursts before the platters limit continuous transfer rates.

How much noise and heat does the 8TB drive add to a 24x7 NAS?

3D Active Balance Plus minimises vibration-induced noise in multi-bay enclosures, and the drive is rated for 24x7 operation with up to 1 million hours MTBF.

What must my NAS already have to install this 3.5 inch SATA drive?

A free 3.5 inch bay that accepts drives up to 26.10mm high, a SATA data cable and a SATA power connector from the NAS power supply.
