Ubiquiti UACC-HDD-S-4TB 4TB 3.5" Surveillance Hard Drive

Ubiquiti UACC-HDD-S-4TB 4TB 3.5" Surveillance Hard Drive

The Ubiquiti UACC-HDD-S-4TB is a 4 TB, 3.5-inch surveillance-grade hard drive engineered for continuous 24/7 operation inside UniFi Protect network video recorders. With a SATA 6 Gb/s interface, 5400 RPM spindle, and 180 TB/year workload rating, this drive is purpose-built for the high-write, low-latency demands of video surveillance — distinct from desktop drives that are not designed for sustained recording loads.

A 1,000,000-hour Mean Time Between Failure (MTBF) rating reflects long-term reliability suitable for unattended NVR deployments. The drive operates across a wide ambient temperature range from 32 °F to 149 °F, supporting use in unconditioned IT closets and equipment cabinets. NDAA compliance and CE/FCC/IC certifications make the UACC-HDD-S-4TB ready for U.S. federal procurement and major international markets, while plug-and-play installation in UniFi UNVR, UNVR-G2, and UNVR-G2-Pro bays keeps deployment fast.
