SkyHawk AI 20TB surveillance drive

This 3.5 inch internal hard drive uses a SATA 6.0Gb/s interface and spins at 7200 RPM with 256MB cache. It is built for continuous video surveillance workloads and uses CMR recording technology. The ImagePerfect AI firmware is designed to deliver zero dropped frames under heavy loads.

Suited for multi-stream AI recording.

The drive supports up to 64 HD video streams and 32 AI streams simultaneously, making it a fit for large-scale network video recorders with analytics. Buyers who need a drive for desktop applications, gaming libraries or occasional backups should consider a different model class. The 550TB per year workload rating and 2M hour MTBF target constant write scenarios rather than mixed use.

SATA 6.0Gb/s interface decides compatibility

Your system must provide a standard SATA data and power connection for this 3.5 inch drive. The physical dimensions are 146.99mm length, 101.85mm width and 26.11mm height, so the drive bay must accommodate that form factor. No other interface type is supported on this model.
