Toshiba has just introduced a new energy-efficient mechanical hard drive for surveillance applications, a DT02-V series that supports 32 HD video streams with a capacity of up to 6TB. The company says the biggest advantage of the HDD in the series is increased reliability. It features a 3.5-inch standard form factor and offers 2TB / 4TB / 6TB three-tier capacity. The spindle speed of 5400 RPM, supplemented by a 128MB cache, is available on the SATA 6 Gbps interface.

The DT02-V series HDDs are primarily targeted at digital video recorder (DVR) and network video recorder (NVR) platform applications and support a variety of enhancements. For example, recording up to 32 video passes simultaneously and supporting 24/7 work in a multi-disk environment.
In terms of performance, the DT02-V Series HDDs have a continuous transmission rate of up to 185 MB/s. In terms of reliability, its nominal maximum write capacity is 180 TB/year, 600,000 load/unload cycles, and the average trouble-free operating time (MTBF) per million hours.
Toshiba says the DT02-V new product offers greater reliability than the previous generation of low-speed MD04ABA-V series HDDs. Although the parameters are slightly lower than enterprise-class mechanical hard drives, they are comparable to the monitoring-grade mechanical hard drives of other manufacturers.
Overall, these drives deliver lower power consumption and higher performance. In recent years, as the demand for video surveillance has grown rapidly, Toshiba has become increasingly bullish on the surveillance-grade hard drive market.
The company has released a 4TB version of the DT02-V Series monitoring disk from now on, the 6TB version will arrive in January and the 2TB version will be in March next year.
