New MQ04 HDD Series model delivers 1TB capacity for portable PCs, game systems and other client storage applications
TOKYO—Toshiba Electronic Devices & Storage Corporation today announced its new MQ04 Series 1TB HDD, designed for applications that require high capacity, highly durable storage, including notebook PCs, game systems, all-in-one slim-line desktop systems and set-top box appliances. Shipments of the MQ04 1TB model start today, with general availability.
The MQ04 Series single-disk model offers the storage industry’s largest capacity per disk for a 2.5-inch HDD, and delivers 1TB of data storage capacity in an ultra-compact 2.5-inch form factor only 7mm high. With a 6 Gbit/s SATA interface, 5,400 rotational speed and a large 128MiB buffer, the new drive is engineered for consistent seek and transfer rate performance, and improves sustained transfer rate performance by 34 percent over the previous 1TB MQ01 generation model. It is expected to meet strong market demand in the client HDD market for high performance, large capacity storage for applications such as notebook PCs, and for recording high resolution images and data.
Toshiba Group positions HDD as a focus business area within its storage business. By enhancing its line-up, Toshiba aims to further enhance solutions for applications ranging from notebook PCs to data centers and high reliability products in both the enterprise and consumer markets, and to ensure that it is uniquely positioned to meet demand across the entire range of customer needs.

 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 1TB = 240 bytes = 1,099,511,627,776 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
