WD Ultrastar DC HC550 Spec and Price in Canada
SATA16TB7200 RPM
The HC550 is WD's data-center nearline drive of the 16-18TB generation: helium-sealed, 7200rpm, a 512MB cache, and a 2.5M-hour MTBF with a five-year warranty, per the WD data sheet. It is CMR with a 550TB/year workload rating, built for servers and enterprise arrays rather than desktop use — the 3.5-inch SATA form factor slots into any chassis, but the price assumes the buyer needs the endurance and the 24/7 rating, not the speed.
