- Reviews
The Toshiba 3.5-inch S300 is built to meet the highest demands. With support for up to 64 high-resolution surveillance video cameras simultaneously and up to 6 TB capacity, it brings everything into clear view. Each S300 is built with the highest-quality components and has passed rigorous tests to ensure 24 x 7 reliability and performance. That’s Toshiba quality you can trust under the harshest working conditions.
Features
Surveillance Digital Video Recorders (sDVR)
Surveillance Network Video Recorders (sNVR)
Hybrid sDVR (analog and IP)
RELENTLESS RELIABILITY
Reliability is a function of component quality and testing. The S300 takes it to a new level, using optimised components to deliver the clear detail from up to 64 video cameras at the same time. Rigorous testing provides performance you can trust day in, day out.
ATTENTION TO DETAIL
When it comes to those events where even the single frame counts, the S300 has been designed to record even the smallest detail. 24/7 reliability and high-performance ensure you will capture every detail to analyze your security footage at any time.
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.
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.
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.
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.
