The Ubiquiti UniFi Enterprise 8TB Hard Drive (Model: UACC-HDD-E-8TB) is a high-performance 3.5-inch SATA mechanical drive designed to deliver non-stop, high-reliability video and data retention across UniFi Protect security ecosystems and enterprise storage setups. Engineered specifically to withstand the grueling multi-stream write demands of modern AI-powered surveillance systems, the drive ensures uninterrupted frame retention and rapid footage retrieval during active investigations.
Featuring a native 8TB storage capacity, a 7200 RPM spindle speed, and a high-speed SATA 6 Gbps interface, the UACC-HDD-E-8TB seamlessly populates single-drive gateways or multi-bay video recorders—such as the UniFi Network Video Recorder (UNVR), UNVR Pro, and Dream Machine Pro / Special Edition. Built with advanced Rotational Vibration (RV) sensors, the drive mitigates multi-drive chassis vibration in high-density multi-bay array configurations. Optimized with dedicated surveillance firmware, it delivers low write-latency performance, energy-efficient thermal management, and an enterprise Mean Time Between Failures (MTBF) rating of 2.0 million hours.
Comprehensive Key Features:
8TB Enterprise Storage Capacity: Provides continuous video footage retention across large fleets of 2K, 4K, and PTZ UniFi Protect security cameras.
Continuous 24/7 Surveillance Workload: Rated for 550 TB/year workload limit—up to 10x the rating of standard desktop hard drives.
High-Speed 7200 RPM Performance: Ensures low-latency video write operations and fast multi-channel playback responses.
Rotational Vibration (RV) Sensors: Integrated vibration compensation safeguards drive health and performance inside multi-bay UNVR chassis setups.
Optimized SATA 6 Gbps Interface: Native 3.5-inch form factor compatible with standard hot-swappable drive bays.
Unified UniFi Controller Monitoring: Fully monitored within UniFi OS for dynamic drive health tracking, temperature telemetry, S.M.A.R.T. status, and RAID array rebuilding notifications.
