WD Red Plus 6TB NAS Drive

The Western Digital WD60EFZX is a 3.5-inch internal hard drive built for network-attached storage. It offers 6TB of capacity, a SATA 6.0Gb/s interface and conventional magnetic recording at 5640 RPM with 128MB cache. The drive is engineered for 24x7 operation in small- to medium-business NAS enclosures.

Suits 1-8 bay NAS builds.

This drive targets NAS systems with up to eight bays and workloads up to 180 TB per year. It is not intended for standalone desktop use, laptop upgrades or high-bay enterprise arrays beyond the supported count. Buyers needing portable storage or non-RAID boot drives should look elsewhere.

Verify SATA power, data cables

Confirm your NAS chassis accepts 3.5-inch drives measuring 147.00mm long, 101.60mm wide and 26.10mm high. Ensure the backplane or controller provides SATA 6.0Gb/s ports and matching power connectors. Check that the firmware environment supports NASware 3.0 for optimal compatibility.

Questions about this item

My NAS has 3.5-inch bays with SATA 6.0Gb/s ports — does this drive fit and connect directly?

Yes, the drive uses the standard 3.5-inch form factor and a SATA 6.0Gb/s interface, so it mounts in any 3.5-inch bay and plugs straight into a SATA 6.0Gb/s port without adapters.

I run a mixed array with older CMR drives — will the 128MB cache and NASware 3.0 firmware on this model cause timing conflicts?

The drive uses CMR recording and NASware 3.0 firmware, both designed for multi-drive NAS environments, so it works alongside other CMR drives without timing conflicts.

After installation, how can I verify the drive is operating at its rated 5640 RPM and 180 TB/yr workload rate?

Check the SMART data for the reported spindle speed and monitor annualised write volume; the drive is built for up to 180 TB/yr in 24×7 NAS use.
