Seagate Exos X18 Spec and Price in France
Exos X18 is Seagate's 16-18TB enterprise nearline drive: 7200rpm, 256MB of cache, a 550TB/year workload rating, and a five-year warranty, per the Seagate data sheet. It is CMR with enterprise firmware tuned for multi-drive arrays and high-density data centers — the same mechanics that later generations (X20, X24) kept while raising capacity. For a workstation or home server it is simply the reliable way to get 16-18TB on SATA.
