Built to perform
With up to 10 TB of storage capacity and support for up to 64 video cameras, the S300 ensures mission-critical surveillance continually records. Real-time drive performance allows higher-resolution video recording and streaming and longer content retention.

Capture every frame, analyse every detail

When analyzing security footage, you can't risk any frame drops. That's why your storage has to provide ultimate performance to detect rapid movements, record the smallest details, and perform face recognition. The S300 has been designed to meet your specialist demands and is built for 24/7 reliability and high-performance to help you never miss a thing.

Designed and tested for compatibility

The S300 has been designed and tested to support up to 64 high resolution cameras, allowing flexible scalability for your security camera systems. Compatible with DVR, NVR, video servers and video management systems for around-the-clock security, the surveillance never sleeps – so that you can.

Industry-leading performance

A 256 MB buffer and high transfer rates meet the demands of surveillance data from higher-resolution camera streams. Improved real-time drive performance is achieved through Toshiba's Dynamic Cache Technology optimizing read and write cycle cache allocation through an on-board cache algorithm and buffer management.

Integrated RV sensors

Regular hard disk drives without RV sensors can affect the performance of a multi-bay system by generating 'knock-on' vibration. The S300 ensures high reliability by minimising vibration effects through their advanced control and sensing technology. Multiple sensors detect the slightest shock and built-in RV sensors also compensate for rotational vibration - eliminating the possibility of 'knock-on' vibration in multi-bay surveillance systems.

High endurance, high reliability

The high-endurance, high-performance components of the S300 withstand harsh environments for superior reliability. High-temperature environments trigger optimized seek speed to support lower power consumption while automatically reducing noise and vibration emissions. Up to one million hour MTTF (Mean time to failure) and 180 TB per year workload rating provide peace of mind when operating security camera systems.

Built to deliver, designed to last

Toshiba is renowned the world over for 50 years of leading innovation – and the power behind its range of hard drives is no exception. Designed for high capacity and excellent performance, you can be sure that Toshiba’s wealth of experience in hard drives is at work in your storage system. A three year extended warranty is also included with the S300 for the ultimate peace of mind.
