Manufacturer description
Western Digital's 6TB WD Red Plus (WD60EFRX) is a 3.5-inch NAS drive built for small- and medium-business arrays and SOHO setups that run 24x7. It uses CMR recording rather than SMR, which matters if you run ZFS, unRAID, or any RAID array that has to rebuild after a disk swap - CMR keeps sustained write behavior predictable during resilver. The 5400 RPM performance class trades peak throughput for lower heat and quieter operation in a populated enclosure, and the 64 MB cache plus SATA 6 Gb/s interface handles typical file-sharing and archiving loads without drama. NASware firmware handles…

Frequently Asked Questions
Is the WD60EFRX CMR or SMR?
It is CMR. Western Digital renamed this model WD Red Plus specifically to separate it from the SMR-based WD Red line. If the box still says WD Red, the WD60EFRX model number confirms you have the CMR version.
Will this drive work in a ZFS or unRAID array?
Yes. Western Digital positions it for RAID array rebuilding on ZFS and other file systems, and the CMR recording is what makes resilver and parity rebuild behavior predictable compared with SMR drives.
How many drives can I put in one NAS with these?
Western Digital builds and tests WD Red Plus for NAS systems of up to 8 bays. For chassis larger than that, step up to a drive rated for higher bay counts.
How much data can I write to it per year?
It supports up to 180 TB per year. Western Digital defines workload rate as user data transferred to or from the drive, annualized as TB transferred times 8760 divided by recorded power-on hours.
What warranty comes with it?
The drive carries a 3-year limited warranty. Check the product listing for current terms and regional coverage before you buy.
