High-capacity disc drives for always-on applications

May 14, 2014 // By Graham Prophet
Toshiba Electronics Europe’s MD03ACA-V series is a high-capacity hard disk drive (HDD) for surveillance and similar applications. Toshiba’s purpose-built line of 3.5-inch HDDs are available in capacities up to 4 TB and provides multi-stream, temperature resistant support for 24/7 storage.

The SATA drives spin at 7200rpm and support the industry-standard 512n sector lengths as well as RV compensation that maintains performance under multiple HDD configuration - making the MD03ACA-V series suited for around-the-clock 24/7 video surveillance storage. Interface speed (SATA 3.0) is up to 6 Gbit/sec and average latency is 4.17 msec. Robust design provides storage to various video recorders including surveillance digital video recorders (SDVR), surveillance network video recorders (SNVR) and Hybrid SDVR, delivering 24/7 operation with a mean time to failure (MTTF) of 1 million hours. The high-capacity HDDs enable support for higher resolution data streams, addresses the need for longer surveillance video retention periods, multi-streaming capabilities, wider temperature resistance and uninterrupted write applications.
