Seagate Exos X16 14TB Renewed Hard Drive
The Seagate Exos X16 14TB offers 6TB more storage than the IronWolf 8TB while keeping the same 7200 RPM speed and 256MB cache. This drive uses a 1.03-inch height, which is slightly thicker than the IronWolf’s 0.79-inch profile. You gain significant capacity for heavy NAS workloads without sacrificing rotational speed. However, this is a renewed unit, so you trade new-condition reliability for higher density.
