Manufacturer description
The Western Digital WD Red Plus 8TB (WD80EFPX) is a CMR NAS hard drive built for small and medium business systems that stay powered on 24x7. It spins at 5640 RPM over a SATA 6 Gb/s interface with a 256 MB cache, and Western Digital rates it for workloads up to 180 TB per year - enough headroom for continuous archiving, file sharing, and RAID array rebuilds. Because it uses conventional magnetic recording rather than SMR, rebuild and resilver behavior stays predictable on ZFS, unRAID, and other parity file systems, which is the main reason the Red Plus line gets specified for NAS duty over…

Frequently Asked Questions
Is the WD Red Plus 8TB CMR or SMR?
It is CMR (conventional magnetic recording). That is why it is recommended for ZFS pools and RAID arrays, where SMR drives can stall during rebuilds and resilvers.
How many drive bays does the WD80EFPX support?
Western Digital builds and tests Red Plus for NAS systems with up to 8 bays. For larger chassis, step up to a drive rated for higher bay counts.
What is the rated workload for this drive?
Up to 180 TB per year. Workload rate is annualized as TB transferred x (8760 / power-on hours), so your real figure depends on how hard the array is worked.
How fast does the WD Red Plus 8TB spin?
5640 RPM, over a SATA 6 Gb/s interface with 256 MB of cache. The lower spindle speed trades peak throughput for reduced heat and noise in an always-on enclosure.
What warranty does the WD80EFPX come with?
A 3-year limited warranty. Terms vary by region, so check the official Western Digital site for the coverage that applies where you bought the drive.
