Manufacturer description
The Seagate Skyhawk 4TB (ST4000VXZ16/016) is a 3.5-inch SATA 6Gb/s hard drive built specifically for DVR and NVR security camera systems rather than general desktop use. Where a standard desktop drive is rated for light duty, Skyhawk is specified for workloads up to 180TB per year and up to 64 simultaneously streaming HD cameras, with enhanced ImagePerfect firmware that targets dropped frames during continuous 24x7 recording. A 64MB cache buffers the write-heavy stream traffic surveillance systems generate, and built-in rotational vibration sensors keep performance stable when you stack…

Frequently Asked Questions
Will the Seagate Skyhawk 4TB work in my DVR or NVR?
It is a standard 3.5-inch SATA 6Gb/s drive purpose-built for DVR and NVR surveillance recorders, so it drops into most bays. Confirm your recorder supports 4TB drives on its compatibility list before ordering.
How many security cameras can this drive record at once?
Seagate specifies support for up to 64 simultaneously streaming HD cameras with zero dropped frames, within a rated workload of up to 180TB per year.

What warranty and data recovery coverage are included?
The drive ships with a three-year limited warranty and three years of in-house Rescue Data Recovery Services. Check the product listing for current terms and registration requirements in your region.
