Toshiba Announces New 2TB Hard Disk Drive for Client Storage Applications
OREANDA-NEWS. Toshiba Electronic Devices & Storage Corporation (“Toshiba”) today announced its new MQ04 Series 2TB HDD model MQ04ABD200, designed for use in notebook PCs, all-in-one and slim-line desktop systems, and other applications requiring high capacity storage and 2.5-inch mobile-class durability.
The MQ04ABD200 dual-disk model delivers 2TB of storage capacity in a compact 2.5-inch, 9.5mm height form factor. The drive’s 6Gbit/s SATA interface and 5,400rpm performance, combined with a large 128MiB buffer, result in a 34 percent increase in maximum transfer rates and a 50 percent improvement in power efficiency compared to Toshiba’s previous 1TB mobile-class model generation, MQ01ABD100.
“Achieving 2TB capacity in the industry-standard 2.5-inch form-factor is a big advance in both value and performance, and helps improve watt per GB to contribute to better battery life in portable PCs,” said Shuji Takaoka, General Manager of Storage Products Division at Toshiba Electronic Devices & Storage Corporation. “With a field-proven two disk 9.5mm design heritage, the new MQ04 2TB model offers excellent value and capacity.”
General availability of the MQ04 2TB model shipment will start today.
 Definition of capacity: A terabyte (TB) is 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1TB = 240 = 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 and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
 Form Factor: "2.5-inch" means the form factor of HDDs. They do not indicate drive's physical size.
 Read and write speed may vary depending on the host device, read and write conditions, and file size.
 A mebibyte (MiB) means 220, or 1,048,576 bytes.
 Power efficiency is calculated based on low power idle power consumption divided by formatted capacity.
