Toshiba Launches High Capacity Hard Disk Drives for Surveillance Applications

Toshiba Corporation’s (TOKYO:6502) Semiconductor & Storage Products Company today announced the launch of the MD03ACA-V series, high-capacity hard disk drives (HDD) for surveillance applications. Toshiba’s purpose-built line of 3.5-inch HDDs are available in capacities up to 4 TB[1]. The 6Gbit/s SATA drives spin at 7,200rpm and support the industry-standard 512B sector lengths with rotational vibration (RV) compensation to keep performance under multiple HDD configuration, making the MD03ACA-V series suited for customers looking for 24/7 video surveillance storage. Mass production shipment in the Japanese market starts from this month.

The robust design of the MD03ACA-V series 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. With up to 4TB of storage, Toshiba’s MD03ACA-V enables 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.

Outline of the New Products

Model Name   Recording Capacity   Size  

Suitable Applications




Height: 26.1 mm

Width: 101.6 mm

Length: 147 mm



- Hybrid SDVR

- 24/7 operation

- MTTF: 1 million hours

- RV compensation

MD03ACA200V   2TB      

[1] Definition of capacity: Toshiba defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.

When it comes to IoT in the enterprise, namely the commercial building and hospitality markets, a benefit not getting the attention it deserves is energy efficiency, and IoT’s direct impact on a cleaner, greener environment when installed in smart buildings. Until now clean technology was offered piecemeal and led with point solutions that require significant systems integration to orchestrate and deploy. There didn't exist a 'top down' approach that can manage and monitor the way a Smart Buildi...
As-a-service models offer huge opportunities, but also complicate security. It may seem that the easiest way to migrate to a new architectural model is to let others, experts in their field, do the work. This has given rise to many as-a-service models throughout the industry and across the entire technology stack, from software to infrastructure. While this has unlocked huge opportunities to accelerate the deployment of new capabilities or increase economic efficiencies within an organization, i...
Recently announced Azure Data Lake addresses the big data 3V challenges; volume, velocity and variety. It is one more storage feature in addition to blobs and SQL Azure database.

“All our customers are looking at the cloud ecosystem as an important part of their overall product strategy. Some see it evolve as a multi-cloud / hybrid cloud strategy, while others are embracing all forms of cloud offerings like PaaS, IaaS and SaaS in their solutions,” noted Suhas Joshi, Vice President – Technology, at Harbinger Group, in this exclusive Q&A with Cloud Expo Conference Chair Roger Strukhoff.
In his session at @ThingsExpo, Tony Shan, Chief Architect at CTS, will explore the synergy of Big Data and IoT. First he will take a closer look at the Internet of Things and Big Data individually, in terms of what, which, why, where, when, who, how and how much. Then he will explore the relationship between IoT and Big Data. Specifically, he will drill down to how the 4Vs aspects intersect with IoT: Volume, Variety, Velocity and Value. In turn, Tony will analyze how the key components of IoT ...

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud wit...
As the world moves towards more DevOps and microservices, application deployment to the cloud ought to become a lot simpler.

In his session at 17th Cloud Expo, Raghavan "Rags" Srinivas, an Architect/Developer Evangeli...
DevOps is gaining traction in the federal government – and for good reasons. Heightened user expectations are pushing IT organizations to accelerate application development and support more innovation. At the same time, budgetary constraints require that agencies find ways to decrease the cost of developing, maintaining, and running applications.
