  1. #1

    Seagate IronWolf 4TB NAS hard drive

    7.0/10verdict: buy

    The Seagate IronWolf 4TB is for people building or expanding a small NAS of up to eight bays who want CMR recording and a 3-year warranty. It suits bulk storage, backups and media libraries where low noise and power draw matter more than raw speed. Buyers need to check which of the two model numbers they are getting, because speed, cache and noise figures differ.

    WD Red Plus 4TB WD40EFPX

    6.9/10verdict: good, not the best

    The WD Red Plus 4TB (WD40EFPX) is for home and small-office NAS owners filling up to eight bays who want a CMR drive. Its 5,400 rpm spindle and low rated noise and power suit a NAS that sits in a living space or runs around the clock. Buyers whose needs go beyond its 180MB/s transfer rate, 180TB/year workload rating or three-year warranty should look elsewhere.

    Synology HAT3300-4T

    6.7/10verdict: good, not the best

    The Synology HAT3300-4T is a 4TB CMR drive for people filling a NAS with Plus Series disks. It suits buyers who want a 180TB/year workload rating, a 3-year warranty and good RAID 5 speeds. It is a less comfortable fit if the NAS sits in a quiet room, because owners report that it is audible.
