The WD Red Plus 4TB is a 3.5-inch internal hard drive built for NAS boxes, using CMR recording rather than the shingled SMR design that hurt earlier Red drives. It spins at 5400 rpm with a 256 MB cache and a SATA 6Gb/s interface, and WD rates it for RAID systems with up to 8 bays. Its 1 million hour MTBF and low 4.7 W read/write draw suit always-on storage in small offices and home labs. Against Seagate IronWolf and Toshiba N300 drives of the same capacity, it is the quieter, cooler-running pick, though slower than 7200 rpm NAS drives.

Owners rate it well for NAS use, praising reliability and quiet operation in Synology and QNAP boxes. Complaints center on speed and on the SMR history of the Red line.
