8TB SATA HDD for NAS workloads

The WD Red WD80EFZX is an 8TB 3.5-inch hard drive spinning at 5400RPM with a 128MB cache and SATA 6Gb/s interface. It is built for always-on network-attached storage enclosures and multi-bay RAID arrays. The drive arrives new and ready for installation in compatible bays.

Suited for RAID arrays, not for desktop boot

This drive suits administrators expanding NAS capacity or rebuilding redundant arrays where sustained write throughput and vibration tolerance matter. It is not intended for single-drive desktop boot duties, portable external use, or systems lacking 3.5-inch mounting points and SATA power connections.

5400RPM spindle speed defines the use case

The 5400RPM rotation rate determines the drive's acoustic profile, power draw, and sustained transfer ceiling. Buyers needing higher random IOPS or lower latency for database or virtualisation workloads should evaluate drives with faster spindle speeds.

Questions about this item

What cables or brackets do I need to install the WD80EFZX in a 3.5" drive bay?

The drive uses a standard SATA data and power connection. No cables, brackets or mounting screws are included, so you must supply those yourself.

Will the WD80EFZX work in a NAS that currently uses 5400RPM SATA drives?

Yes. It matches the same 5400RPM spindle speed and SATA 6Gb/s interface, so it will integrate with existing 5400RPM drives without speed mismatch.

How can I verify the WD80EFZX is recognised with its full 8TB capacity after installation?

Check the BIOS or operating system disk utility; it should report the drive as WD80EFZX with 8TB capacity and 128MB cache.
