Toshiba has introduced a new line of energy-efficient hard drives for surveillance applications. The new DT02-V series HDDs will support up to 32 HD streams and offer capacities of up to 6 TB. The company says that the key advantage that the new drives will provide over its direct predecessors is improved reliability.

Toshiba’s DT02-V family of 3.5-inch hard drives will include models with 2 TB, 4 TB, and 6 TB capacities featuring a 5400 RPM spindle speed, a 128 MB cache buffer, and a SATA 6 Gbps interface. Being aimed at digital video recorder (DVR) and network video recorder (NVR) platforms applications, the DT02-V HDDs support a variety of enhancements, such as ability to record data from up to 32 cameras simultaneously as well as being rated to run 24/7 – including in multi-drive environments.

Performance-wise, Toshiba expects its DT02-V HDDs to offer up to 185 MB/s sustained sequential data transfer speeds. As for reliability, they are rated for up to 180 TB per year workload, 600,000 load/unload cycles, and one million hours MTBF, which is significantly below ratings of enterprise-grade hard drives, but is in line with other HDDs for surveillance applications.

According to Toshiba, its new DT02-V hard drives offer higher reliability compared to the prior-generation low-spin MD04ABA-V HDDs. Overall, the drives offer higher performance at a lower level of power consumption.
