Smart performance delivers
The S300 is a smart performer. That's because Toshiba's Dynamic Cache Technology optimises read and write cycle cach allocation through buffer management and a special on-board cache algorithm.

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.

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 up to 180 TB per year workload rating provide peace of mind when operating security camera systems.
