About Toshiba S300 4TB

The Toshiba S300 4TB Surveillance HDD is a purpose-built 3.5-inch hard drive engineered specifically for 24/7 security environments. While standard desktop drives are designed for intermittent use, the S300 is optimized for the rigorous, "always-on" demands of high-definition video recording in DVR (Digital Video Recorder) and NVR (Network Video Recorder) systems.Key Performance SpecificationsThe 4TB model typically operates at a rotational speed of 5,400 RPM. This lower-spin design is intentional for surveillance; it reduces power consumption and heat generation, which is critical for drives running 365 days a year. It features a generous 128MB to 256MB cache (depending on the specific sub-model/batch) and utilizes Toshiba’s Dynamic Cache Technology. This algorithm optimizes the allocation of cache during read and write cycles to prevent frame drops—ensuring that every second of critical footage is captured without stuttering.Reliability and ScalabilitySurveillance systems often house multiple drives in close proximity, which can cause performance-degrading vibrations. The S300 addresses this with integrated Rotational Vibration (RV) sensors. These sensors detect and compensate for "knock-on" vibrations in multi-bay systems, maintaining high reliability even in dense hardware setups.Workload Rating: It is rated for a workload of up to 180 TB per year.Camera Support: It can simultaneously handle streams from up to 32 to 64 high-resolution cameras (model dependent), making it suitable for both residential setups and small-to-medium business security grids.Durability: With a Mean Time To Failure (MTTF) of 1 million hours, it is built to survive harsh, high-temperature environments that would typically cause consumer-grade drives to fail prematurely.Summary TableFeatureSpecificationCapacity4 TBForm Factor3.5-inch SATARotational Speed5,400 RPMInterfaceSATA 6.0 Gbit/sAnnual WorkloadUp to 180 TB/year24/7 OperationSupported
