Surveillance storage for continuous recording

The Seagate SkyHawk ST4000VXZ16 is a 4 TB mechanical hard drive built for DVR and NVR security systems. It handles workloads of up to 180 TB per year and supports 64 simultaneous HD camera streams. The 7200 RPM spindle and 256 MB cache deliver sustained write performance for 24×7 video capture.

Standard 3.5-inch SATA installation

The drive fits a regular 3.5-inch bay and connects through a SATA 6 Gb/s interface. Built-in RV sensors help maintain performance in multi-bay enclosures by compensating for vibration. No special drivers or configuration are required beyond the recorder’s own setup.

SATA interface limits sustained throughput

The SATA 6 Gb/s link caps maximum sequential transfer at the interface’s theoretical ceiling. Mechanical latency and the 7200 RPM rotation speed determine real-world sustained rates, which fall well below the interface maximum. The drive is not suited for random-access workloads or boot-drive duties.

商品問答

How can I verify the ST4000VXZ16 is operating correctly after installing it in my NVR?

Check that the NVR recognises the full 4000 GB capacity and shows zero dropped frames across up to 64 camera streams; SkyHawk Health Management will also report drive status and workload against the 180 TB/year rating.

What comes in the box with the ST4000VXZ16 and what must I source separately?

The drive itself is supplied; a SATA data cable, SATA power lead, mounting screws and any 3.5-inch drive tray or caddy required by your recorder are not included and must be purchased separately.

Which cache size should I choose for the 4 TB SkyHawk model?

This specific ST4000VXZ16 variant is fitted with 256 MB cache; there is no alternative cache option for this 4 TB capacity in the SkyHawk line.
