Who is the WD Red Plus 4TB NAS Hard Drive for?
NAS, surveillance recorders, servers and desktops that need reliable capacity at a low cost per terabyte. WD Red Plus 4TB NAS Hard Drive is listed in our NAS HDD range.
What to check before you buy
- Pick the duty class: NAS, surveillance and enterprise drives are built for 24x7 use, desktop drives are not.
- Confirm interface (SATA or SAS) and form factor (3.5 or 2.5 inch) against your enclosure or server backplane.
- Check the recording method (CMR is preferred for RAID rebuilds; SMR suits archive and light use).
- Buy matching drives for a RAID set and keep one spare, ideally from different production batches.
- Compare the workload rating (TB per year) and warranty period, not only the capacity.
