Hikvision DS20HKVS-VX1 — 2TB Surveillance Hard Drive
Hikvision's own-brand 2TB CCTV hard drive: 24/7 rated, 128MB cache and support for up to 32 HD camera streams.
Overview
The Hikvision DS20HKVS-VX1 is a 2TB surveillance hard drive designed for continuous video recording in DVRs and NVRs. Unlike a desktop drive, it is built to write video around the clock: it is rated for 24/7 operation, a 180TB/year workload and a 1,000,000-hour MTTF. The 128MB cache helps keep recording smooth and guards against dropped frames across up to 32 high-definition camera streams.
It uses the industry-standard 3.5-inch form factor and SATA 6Gb/s interface, so it fits the drive bay of Hikvision recorders. At 5400rpm it runs cool and quiet, drawing just 4.01W in operation. 2TB is a popular size for 4 and 8 channel home and small business systems.
