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.

Toshiba considers hard drives for surveillance applications as a very important market for the company as demand for such HDDs is expected to grow in the coming years, particularly in China. As a company that wants to expand sales of its storage devices, Toshiba believes it is crucial for it to address growing markets.

The company is sampling the 4 TB model of the new HDDs today, while samples of 6 TB drives are due in January, and samples of 2 TB SKUs are expected in March. It is unclear when the manufacturer plans to start volume sales of the new hard drives, but it is safe to say that this should happen in 2020.

    Hey! I can make the same argument about steam locomotives: The era of steam locomotives is NOT over! You don't believe me? There are many people who love steam locos, i am one of them. And there are many steam locos still in operation. And just yesterday i was taking a ride on a steam train. Just because locomotive manufacturers have some reasons to not build steam engines anymore doesn't make steam locos bad or dead.

    And Union Pacific doesn't just run their steam locomotives around to allow people to take pictures, they haul actual revenue trains with them. Even some of those smaller tourist railroads, where you ride behind a steam locomotive on the weekend, haul freight with the same locomotive during the week.

    Yeah, railroads in Europe do this on main and branch lines as well, occasionally. Mostly in passenger service (both as part of the regular train schedule or as special charter trains), but doing some freight services once in a while is also not unheard of. :)

    I also have a unicorn in my backyard. I needed to muzzle it so that it stopped poking me with it's horn, but there are no muzzles for unicorns. You know what I did? I used an old Slackware CD! So we really do need optical drives!

    More seriously, in 2009 the M-Disc came out and it's still used by quite a few people for permanent storage. The M-Disc has not been bettered by modern SSDs, HDDs, Tapes, or any other consumer oriented product I'm aware of. Thus optical drives are still a worthwhile investment for a user interested in long term storage solutions (everyone).
    The alternative someone uninformed will point me to is cloud storage. In case you've never read the user agreement, I know people who have (but not for every storage provider), and they state that the storage is not permanent and that data loss can occur at any time through a disclaimer of liability.
