Protect video evidence with a drive built for always-on surveillance storage. The Seagate SkyHawk ST4000VX007 pairs 4 TB of capacity with a 5,400 RPM spindle speed and 256 MB cache, giving DVR and NVR systems the headroom they need for continuous recording, playback, and retention. This 3.5-inch SATA drive is designed for environments where drives spend their lives writing, not idling. The lower spindle speed helps keep acoustics and power draw in check while maintaining the sustained behavior surveillance arrays depend on. For integrators and IT teams standardizing on cost-effective local storage, SkyHawk offers a practical balance of capacity and endurance for multi-camera deployments. Choose this model when you need more than a desktop drive in a recorder chassis. It is aimed at 24/7 operation, where missed frames and premature drive wear are not acceptable. For small to mid-size surveillance systems, the 4 TB class is a strong fit for keeping recent footage available without overcommitting budget or rack space.
