3TB CMR drive for NAS

The WD Red Plus WD30EFZX is a 3TB 3.5-inch hard drive built for small- to medium-business NAS enclosures. It uses conventional magnetic recording and a SATA 6.0Gb/s interface to deliver consistent throughput in multi-bay systems. The 128MB cache helps sustain performance during concurrent read and write operations. It is rated for 24x7 operation in up to eight-bay configurations.

Upgrade from smaller or archive-class drives

Replace lower-capacity drives or shingled-recording models when your array needs more raw space and predictable rebuild behaviour. The 180 TB/yr workload rating and CMR technology make the step worthwhile for RAID sets that see frequent parity rebuilds or ZFS resilvering. Drives limited to lighter duty cycles or fewer supported bays will not match this endurance profile.

Buyers needing more than eight bays

This model is not for deployments that exceed eight drive bays or require the higher workload rating of the Red Pro line. Systems that demand 24-bay support or sustained write intensity beyond 180 TB/yr should look elsewhere. Verify that your NAS firmware lists this drive as compatible before ordering.

Soalan tentang produk ini

Will the 147.00mm length and 26.10mm height fit my 3.5-inch NAS bay?

Yes, the drive measures 147.00mm long, 101.60mm wide and 26.10mm high, matching the standard 3.5-inch form factor used in most NAS enclosures.

Does the SATA 6.0Gb/s interface require any jumper or driver setup during installation?

No jumper or driver is needed; connect the SATA data and power cables, and the NAS firmware will recognise the drive automatically.

What workload rating should I expect before planning a replacement?

The drive is rated for up to 180 TB per year, so plan a replacement once your annual written data approaches that figure.
