Toshiba 4TB S300 Surveillance Hard Drive (3.5", SATA III, 5400rpm, 128MB Cache)

Continuous reliability for surveillance

The Toshiba S300 4TB surveillance hard drive is built for 24/7 video recording in demanding security systems. Engineered for reliability, it supports continuous operation so your footage is always captured and stored when you need it.

Optimised for multi‑camera systems

Designed for scalable video surveillance, the S300 can handle the data streams of multiple high‑resolution cameras at once. It is suitable for use in digital video recorders (DVR), network video recorders (NVR), and hybrid systems combining analogue and IP cameras.

Smart performance with Dynamic Cache Technology

Toshiba Dynamic Cache Technology uses advanced cache and buffer management algorithms to optimise how data is allocated during read and write cycles. The result is stable, responsive performance tailored to surveillance workloads.

Built‑in vibration and rotation control

In multi‑bay enclosures, vibration can affect drive stability. The S300 integrates modern control and sensing technologies, including rotational vibration (RV) sensors, to detect and compensate for vibration. This helps maintain consistent performance and reliability in multi‑drive surveillance systems.

Durable components for 24/7 operation

The S300 uses robust, high‑performance components designed to withstand demanding environmental conditions typical of surveillance installations. In higher temperature environments, the drive can adjust its operating mode to optimise power usage and help reduce noise and vibration.

Toshiba expertise and 3‑year warranty

Backed by Toshiba’s decades of storage innovation, the S300 series combines capacity, performance and reliability for video security applications. The drive includes a 3‑year warranty for added peace of mind when protecting your critical surveillance data.
