Seagate SkyHawk 3.5" 4TB, 5400 RPM, 256MB, SATA III Hard Drive for Surveillance

The Seagate SkyHawk ST4000VX016 is a 4 TB internal hard drive with a 3.5-inch form factor, specifically engineered for surveillance systems. It utilizes a SATA 6 Gb/s interface and is built for continuous 24/7 operation, making it suitable for deployment in network video recorders (NVRs) and surveillance servers. The drive's architecture is focused on providing reliable, long-term storage for constant video recording from multiple camera streams. Its components are selected to withstand the demands of an always-on surveillance environment.

This drive operates at a spindle speed of 5400 RPM and is equipped with a 256 MB cache to manage data flow from high-resolution cameras. To maintain performance in multi-drive systems, it incorporates rotational vibration (RV) sensors that help mitigate the effects of vibration from adjacent drives. The unit is rated for a workload of up to 180 TB per year, and includes S.M.A.R.T. technology for monitoring drive health and operational status, which is a key consideration for data integrity in security applications.
