Keep surveillance infrastructure recording without compromise with the Seagate SkyHawk AI 20 TB hard drive. This 3.5-inch internal SATA drive is built for video-centric storage systems where capacity, sustained write behavior, and long retention windows matter more than consumer desktop features. The 20 TB class gives security teams room for higher-resolution streams, longer archive periods, and larger camera counts before expansion becomes necessary. In practical terms, that means fewer drive bays consumed per terabyte of retained footage and a cleaner path to scaling NVR or AI video platforms. CMR recording is an important detail for surveillance arrays because it supports predictable behavior under continuous write workloads. That makes this drive a better fit for recording systems than lower-cost alternatives that are not tuned for the same duty cycle. For buyers comparing options, the premium is justified by the storage density and the workload profile it is intended to serve. Choose SkyHawk AI when the storage layer is part of a security system that cannot afford gaps, rework, or frequent capacity churn. It is built for the kind of always-on video retention that demands more from a drive than simple file storage.
