Seagate SkyHawk AI 20TB Surveillance Hard Drive

The Seagate SkyHawk AI 20TB internal hard drive delivers enterprise-grade storage capacity specifically engineered for AI-enabled surveillance systems and multi-camera NVR environments. This 3.5-inch SATA III drive operates at 7200 RPM with a 256MB cache buffer, providing the sustained performance required for continuous security recording operations.

High-Performance Surveillance Storage

Built for demanding surveillance applications, this drive achieves sustained data transfer rates up to 248MB/s with burst speeds reaching 600MB/s. The 7200 RPM spindle speed and 4.16ms average latency ensure smooth multi-stream video recording and playback. Native Command Queuing with command ordering optimizes performance when handling multiple simultaneous video streams from AI-enabled security cameras.

Advanced Recording Technology

Perpendicular recording technology enables the drive's massive 20TB capacity across 10 discs with 20 heads, achieving an areal density of 1146 Gb/in². The 256MB cache buffer (262,144KB) manages data flow efficiently during peak recording periods. Full-track multiple-sector transfer capability operates without local processor intervention, reducing system overhead during continuous operation.

24/7 Reliability Features

The Top Cover Attached motor design provides excellent vibration tolerance in multi-drive NVR chassis configurations. PowerChoice technology offers selectable power savings for energy-efficient operation during extended deployment. S.M.A.R.T. drive monitoring and reporting enables proactive health tracking, while SeaTools diagnostic software performs comprehensive drive self-tests to ensure operational integrity.

Enterprise-Grade Specifications

This surveillance-optimized drive supports latching SATA cables and connectors for secure connections in rack-mounted environments. The Worldwide Name (WWN) capability uniquely identifies each drive for inventory management in large-scale installations. Operating temperature range spans 0°C to 65°C ambient, with startup current of 2.0A peak at 12V. The drive reaches ready state within 25-30 seconds from power-on or standby modes.
