Original Press Release:
Toshiba Introduces Half-Terabyte 2.5-inch Hard Disk Drive with Ultra-Quiet Acoustics and Enhanced Durability
State-of-the-Art Design Features Provide a Valuable Storage Solution for High-Capacity Mobile PCs, Game Consoles, Printers and External Storage
IRVINE, Calif., Nov. 18 /-- Toshiba Storage Device Division (SDD), the pioneer in small form factor hard disk drives (HDDs), today announced a half-terabyte 5,400 RPM, Serial-ATA (SATA) 3.0 Gb/s 2.5-inch HDD with a number of enhanced features that improve the user experience in mobile applications, as well as other digital devices.
Available in capacities from 500GB(1) to 120GB, the super-quiet and durable MKxx55GSX series is targeted for integration into notebook PCs, sub- notebooks, small form factor and energy star PCs, game consoles, printers and external storage devices.
This new family raises the bar in acoustic performance for mainstream high-capacity HDDs. Advanced servo techniques combined with mechanical design changes minimize noise emanating from the MKxx55GSX drives, making them nearly inaudible during operation, with some models performing close to the threshold of human hearing.
In addition, optimizations in mechanics and servo design have boosted the durability of the series with operating shock tolerance matching the highest levels available on the market today. To further protect user data against potentially hazardous external events, free-fall sensor (FFS) options are available on the new MKxx55GSX series. Toshiba's state-of-the-art FFS technology enables the HDD to respond to drop events, providing additional protection to mobile devices if they are disturbed during operation.
"With a number of value-added technology features, this new 2.5-inch HDD series addresses the need for capacity and durability in mobile applications, while enhancing the overall user experience by minimizing noise from the storage component," said Maciek Brzeski, vice president of marketing at Toshiba Storage Device Division. "The acoustic performance renders these HDDs nearly inaudible, which is ideal for home entertainment applications, while the durability features appeal to mainstream mobile PC users. This family of products offers a comprehensive storage solution for integration into a wide range of applications."
Dedication to Environmentally Conscious HDDs
The new MKxx55GSX family reflects Toshiba's ongoing commitment to enhance the environmental soundness of its products by discontinuing use of certain chemical substances and reducing carbon dioxide emissions during operation for each successive HDD generation. Toshiba has eliminated specified hazardous halogens and toxic chemicals such as polyvinyl chloride (PVC), brominated flame retardants (BFR), antinomy trioxide and red phosphorus across all components incorporated in the drive. In addition, the 500GB MK5055GSX achieves a 20 percent improvement in energy consumption efficiency during operation over previous generation 2.5-inch products.(2)

(1) One Gigabyte (1 GB) means 109 = 1,000,000,000 bytes using powers of 10. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1 GB = 230 = 1,073,741,824 bytes, and therefore shows less storage capacity. Available storage capacity will also be less if the computer includes one or more pre-installed operating systems, pre-installed software applications or media content. Actual formatted capacity may vary.
(2) Energy consumption efficiency is calculated based on power consumption divided by formatted capacity, as defined by Japanese law. Compared to the previous generation 160GB MKxx52GSX product, the MK5055GSX provides a 20% improvement in energy consumption efficiency.
