Toshiba 1.8-Inch HDD at 220GB, 5mm Z-Height

Toshiba Storage Device Division announces the first 1.8" drives with low-insertion force (LIF) SATA (Serial ATA) connectors, enabling a 10% smaller footprint compared to standard 1.8" drives using microSATA connectors.

Developed for use in multiple devices, including tablets, consumer electronics devices and external HDDs, the new MKxx39GSL series offers three models, at 160GB (MK1639GSL), 200GB (MK2039GSL) and 220GB (MK2239GSL) capacities. The MK2239GSL features the largest capacity 1.8" single-platter HDD (5mmH) available. The MK2239GSL, MK2039GSL, and the MK1639GSL are designed for the most demanding mobile computing applications, surpassing 2.5" HDDs in terms of vibration robustness, low power consumption, and quiet operation. Samples will be available for customer qualification in February.

"These new drives build on Toshiba’s history of innovation and leadership in the 1.8" drive segment," said Maciek Brzeski, vice president of mobile marketing at Toshiba Storage Device Division. "Designers of next-generation consumer electronics, tablets, and mobile devices need disk drives that will stand up to the demands of day-to-day usage in a world increasingly defined by mobility and connectivity to all forms of content. These newest members of our 1.8" family are designed to meet those demands."

The MKxx39GSL family is designed for applications requiring not only the smaller, lighter footprint of 1.8" drives, but also the highest possible storage capacities. Both feature a 16MB buffer for improved performance. The drives are capable of withstanding the demands of mobility usage, tolerating up to 1,500Gs of non-operational shock and 600Gs of operational shock, compared to 900G of non-operational shock and 400G of operational shock for the most robust 2.5-inch HDDs currently available. The drives are also quiet, operating at 14dB at idle and 15dB at seek, and require only 0.35 Watts of power at low power idle, the smallest power consumption levels for any SATA drive. It is delivered in a form factor of just 48g/5x54x71mm.

Toshiba has pioneered the development and advancement of 1.8" drives, starting with the industry’s first volume 1.8" drives in 2000. Industry analyst firm IDC reported that Toshiba shipped more than 92% of all 1.8" drives on a global basis in the third quarter of 2010.

"The proliferation of devices targeted at media-savvy and media-hungry consumers and businesses have been a major factor in the continued demand for higher-capacity mobile hard disk drives," said John Rydning, research director, IDC. "Regardless of the device, customers expect to be able to store and access their favorite content, applications, and key data wherever they are."
