Manufacturer description
The WD Red Plus WD30EFRX gives your NAS 3TB of CMR storage built for the 24x7 duty cycle that desktop drives were never designed to survive. Western Digital's NASware firmware handles the compatibility and error-recovery behavior multi-bay enclosures expect, so RAID rebuilds on ZFS, Synology, QNAP, and unRAID arrays complete without the drive dropping out mid-parity-check. The 5400RPM performance class keeps heat and acoustics down in a stacked bay, and the 64MB cache plus SATA 6 Gb/s interface covers the sequential throughput a gigabit or 2.5GbE share will actually use. CMR recording is the…

Frequently Asked Questions
Is the WD30EFRX CMR or SMR?
CMR. This model is part of the WD Red Plus line specifically because it uses CMR technology, separating it from the standard WD Red line that uses SMR. Confirm by the WD30EFRX model number — some units still ship in transitional WD Red labeling but are the CMR version.
How many drive bays does it support?
Western Digital builds and tests WD Red Plus for NAS systems up to 8 bays. The wider WD Red Plus family spans 1TB to 14TB capacities across that same 8-bay support envelope.
Will it survive running 24/7?
Yes — it is specified for small and medium business NAS systems in a 24x7 environment, with a supported workload rate up to 180 TB per year. Workload rate is annualized user data transferred to and from the drive.
What warranty does it come with?
A 3-year limited warranty from Western Digital. Check the product listing for current terms and regional coverage before you buy.
Is 5400RPM fast enough for a home NAS?
For file sharing, archiving, and media streaming over gigabit or 2.5GbE, yes — the SATA 6 Gb/s interface and 64MB cache cover the sequential throughput those links can carry. Random-heavy workloads like VM datastores benefit more from a 7200RPM drive.
