WD Red Plus 2TB NAS Hard Drive
2TB CMRSATA 6 Gb/s5400 RPM64 MB cache180 TB/year
The WD Red Plus 2TB (part number WD20EFPX) is a 3.5-inch CMR NAS hard drive running at 5400 RPM with a 64 MB cache and sustained transfers of up to 180 MB/s over SATA 6 Gb/s. Western Digital positions the Red Plus line for small to medium network attached storage of up to eight drive bays, rated for 24x7 operation at a workload of 180 TB per year.
Before you buy: this is a bare 3.5-inch internal drive with no mounting screws, SATA cable or enclosure in the box. It needs a bay with a SATA 6 Gb/s port and a SATA power connector. Red Plus is rated for enclosures of up to eight bays; for larger arrays or heavier write workloads Western Digital directs you to WD Red Pro instead.
Best For
✓ Small and medium NAS enclosures
Rated by Western Digital for systems of up to eight drive bays, with NASware 3.0 firmware tuned for NAS operating systems.
✓ 24x7 home and office file servers
Built for continuous operation at a 180 TB per year workload, well above a desktop drive but below the Pro tier.
✓ RAID arrays
Time-limited error recovery stops the drive dropping out of a RAID set while it retries a bad sector.
✓ Quiet, low-power builds
At 4.0 W during read and write and 21 dBA idle, it is one of the least intrusive drives you can put in a home NAS.
Key Features
CMR, not SMR
Conventional magnetic recording writes tracks without overlapping them, so random writes and RAID rebuilds stay predictable across the whole 2TB. This matters because other Western Digital consumer lines do use SMR.
NASware 3.0 firmware
Power management, error recovery and vibration handling are tuned for NAS operating systems rather than desktop use.
180 TB per year workload
Roughly three times the annual read and write rating of a typical consumer desktop drive.
5400 RPM spindle
Balanced for NAS duty, where sustained throughput and low heat matter more than seek times.
64 MB cache
A DRAM buffer that absorbs bursty write traffic before it reaches the platters.
600,000 load/unload cycles
Rated head park cycles, twice what a desktop-class mechanism is specified for.

Frequently Asked Questions
Does the WD20EFPX work with Synology and QNAP NAS units?
Yes. It is a standard 3.5-inch SATA 6 Gb/s drive and fits any enclosure with a SATA bay. Capacity ceilings differ between NAS models, so check your specific unit on the vendor compatibility list before ordering.
Is the WD20EFPX CMR or SMR?
CMR. Western Digital lists the entire Red Plus line as conventional magnetic recording, which is the reason Red Plus exists as a separate line from the SMR drives elsewhere in the WD consumer range.
What is the difference between WD Red Plus and WD Red Pro?
Red Plus is rated for up to eight bays with a 180 TB per year workload and runs at a lower spindle speed. Red Pro runs at 7200 RPM in every capacity, is rated to 550 TB per year and carries no bay limit. Both are CMR and both suit 24x7 operation.
What do I need to know before buying the WD20EFPX?
It ships as a bare internal drive with no cables, screws or enclosure. You supply the SATA data and power connections, and you should keep a separate backup since RAID protects against drive failure, not against deletion or ransomware.
Singular Expert Insight
Red Plus is the sensible middle of the NAS range: you get CMR recording and NAS firmware without paying the Pro premium, and in a two to four bay enclosure the difference in real use is small. The number to watch is the workload rating, since at 180 TB per year this drive is sized for a household or small office rather than a busy shared array. If your enclosure has more than eight bays or you run nightly full backups, step up to WD Red Pro. Browse our NAS hard drives or, if you are choosing the enclosure too, our NAS, DAS and RAID storage appliances.
Buyer's Guide
Buy this if
You are filling a two to eight bay NAS that runs continuously and you want CMR recording without paying for the Pro tier.
Skip if
You run a large array, heavy nightly writes or more than eight bays. WD Red Pro is rated for that and this drive is not.
Also consider
WD Red Pro for heavier NAS duty, WD Purple for surveillance recorders, or an internal SSD if you need speed rather than capacity.
