Future-ready performance
Trust Toshiba’s expertise to power a surveillance system that works as hard as you do. The S300 AI Surveillance Hard Drive delivers continuous, high performance with up to 24 TB of storage and support for 64 cameras and 32 AI streams. Built for AI-driven environments, it’s optimized for nonstop video capture and intelligent analysis of large data volumes.
Why OptiFrame™ Matters
Built to Protect Every Frame
Modern surveillance systems must record video continuously while AI simultaneously analyzes stored video data for object detection, face recognition, and behavior insights. These mixed workloads can overload conventional storage and risk dropped frames. OptiFrame™ firmware is purpose-built to protect recording continuity by intelligently managing AI-driven workloads. S300 AI + OptiFrame™ combines surveillance-grade hardware with workload-aware firmware engineered to keep AI-powered security systems recording continuously even while real-time analytics run in the background.
Recording-First Intelligence
Prioritizes continuous video capture by intelligently managing recording, AI analysis, and metadata workloads in real time.
Cache Protection for Reduced Frame Loss
Reserves and protects recording write buffers so AI analysis activity cannot disrupt video streams, even under heavy load.
Adaptive Scheduling for 24/7 Surveillance
Groups sequential recording writes and intelligently paces AI reads to maintain predictable, stable operation as systems scale.
No detail left behind
In intelligent surveillance, precision is everything. Frame drops can mean missed moments — and missed opportunities. That’s why the Toshiba S300 AI is engineered for peak performance, capturing fast motion, fine detail, and facial recognition with unwavering accuracy. With capacities from 8 TB to 24 TB, it’s built for 24/7 reliability, high-volume data analysis and long-term video retention - ideal for large-scale deployments where every frame counts.
