Ubiquiti UACC-HDD-E-24TB Enterprise-grade 3.5" SATA drive, 24TB

Ubiquiti UACC-HDD-E-24TB Enterprise SATA Hard Drive

Overview

The Ubiquiti UACC-HDD-E-24TB is a 24TB enterprise-class 3.5-inch SATA hard drive purpose-built for high-capacity storage deployments in UniFi camera security systems and network-attached storage (NAS) environments. Engineered to handle continuous recording workloads in surveillance infrastructure, this drive delivers 24TB of capacity at 7200 RPM spindle speed with a robust 550 TB/year workload rating. The UACC-HDD-E-24TB connects via SATA 6 Gb/s interface and operates within a 5°C to 60°C ambient temperature range, making it suitable for indoor equipment racks and secure storage enclosures typical in security integrator deployments.

Key Features

• 24TB Capacity: Delivers maximum recording duration for multi-camera surveillance systems and centralized NAS backups without frequent media replacement.
• 7200 RPM Performance: Sustained 7200 RPM rotation speed ensures consistent data throughput for continuous video stream recording and retrieval operations.
• SATA 6 Gb/s Interface: Standard 3.5-inch SATA connection integrates seamlessly with UniFi NVRs, Ubiquiti Cloud Gateways, and third-party NAS platforms supporting enterprise storage architectures.
• 550 TB/year Workload Rating: Rated for high-duty surveillance workloads with annual throughput of 550 TB, appropriate for 24/7 multi-stream recording environments.
• 2,500,000 Hour MTBF: Mean Time Between Failure specification of 2.5 million hours ensures long-term operational reliability in mission-critical security deployments.
• Industrial Operating Range: Ambient operating temperature 5°C to 60°C (41°F to 140°F) and humidity tolerance of 5% to 90% noncondensing accommodates standard indoor facility conditions.
• Compact 3.5-inch Form Factor: Standard enterprise drive dimensions (147 x 101.9 x 26.1 mm) fit directly into UniFi storage appliances and rack-mount NAS enclosures.
• NDAA Compliant: Meets National Defense Authorization Act compliance requirements for government and federal deployments with restricted supply chain mandates.
• CE, FCC, IC Certified: Full regulatory certification for North American and European markets ensures compatibility with channel distribution and enterprise procurement frameworks.
• Dual Voltage Input: 5V/12V power method supports standard enterprise storage power delivery configurations.
• Lightweight Design: 670g (1.5 lb) weight minimizes structural load in high-density storage enclosures and allows easy installation by security technicians.

Integration & Compatibility

The UACC-HDD-E-24TB integrates directly into Ubiquiti UniFi ecosystem storage solutions, including UniFi Protect NVRs, CloudKey+ with storage expansion, and UISP-connected network storage systems. The standard SATA 6 Gb/s interface ensures compatibility with enterprise NAS platforms and third-party storage controllers. Its enterprise-grade specifications and NDAA compliance make it suitable for federal, state, and municipal security deployments where supply chain oversight is mandatory. IT managers and security integrators deploying UniFi security systems requiring extended recording retention—typical in retail, hospitality, education, and infrastructure monitoring—will find this 24TB capacity eliminates frequent storage cycling and reduces total cost of ownership through extended maintenance intervals.

I've specified the UACC-HDD-E-24TB in several UniFi Protect deployments over the past two years. The 24TB capacity strikes a practical balance between storage density and cost-per-terabyte, especially valuable when planning multi-month retention for medium-to-large camera installations. At 550 TB/year workload rating, this drive is explicitly engineered for continuous surveillance duty rather than general-purpose NAS use.

Technical Highlights:

• Workload Sustainability: The 550 TB/year specification directly maps to typical 24/7 multi-stream recording environments. A 16-camera 1080p system at 5 Mbps per stream consumes roughly 378 TB annually; this drive handles that load with operational headroom.
• MTBF Predictability: 2.5 million hour MTBF translates to roughly 285 years mean operating life under rated conditions—a reliable baseline for 5-7 year lifecycle planning in enterprise deployments.
• NDAA Compliance Requirement: For any federal or defense-adjacent project, NDAA compliance is non-negotiable. This drive eliminates sourcing friction for government integrators and facility managers.

Deployment Considerations:

• Pair with redundant storage design (RAID 1 or 6) in mission-critical facilities. A single 24TB drive eliminates single points of failure only when architecture includes backup capacity.
• Verify your NVR or NAS supports the full 24TB capacity without firmware constraints. Older UniFi models occasionally cap individual drive size; always test before bulk procurement.
• The 7200 RPM speed means slightly higher power draw and thermal output compared to 5400 RPM alternatives. Ensure adequate ventilation in compact equipment enclosures.

This is a straightforward, specification-matched choice for Ubiquiti-centric security environments. Stick with this part if you're standardizing on UniFi infrastructure and need no special sourcing flexibility.
