The WD Red Plus 3TB is a 3.5-inch internal hard drive built for NAS enclosures and always-on storage. It spins at 5400 rpm with 64MB of cache, uses CMR recording rather than shingled SMR, and is rated for a 1 million hour MTBF. It suits small NAS owners and home servers that need a reliable multi-bay drive; against Seagate IronWolf and Toshiba N300 it competes on CMR reliability and low noise rather than speed.
