Seagate SkyHawk 4TB 3.5" Surveillance HDD – SATA III, 256MB Cache, Up to 64 Cameras (ST4000VX004)

Your NVR's been dropping frames, or the footage you need from last Tuesday is just… gone. SkyHawk was designed so that doesn't happen. The Seagate SkyHawk 4TB writes continuously at 180 MiB/s sustained throughput, handles up to 64 camera streams, and runs 24/7 without the heat or wear that kills a desktop drive in eighteen months. ImagePerfect Firmware catches read errors before they corrupt a clip. RV sensors keep multi-drive NVRs from interfering with each other. MTBF is one million hours. If you're running a shop, a school gate, or a small office and you need footage that's actually there when you ask for it, this is the drive
