Toshiba announces 2.5-inch 100GB HDD


Toshiba today took the lead once again in the largest and smallest department. The MK1031GAS is the highest capacity 2.5-inch HDD while remaining only 9.5mm high. This will advance the capacity for notebooks and personal video players.

“We are delighted to announce the world’s highest capacity 2.5-inch HDD,” said Amy Dalphy, manager, HDD business unit, Toshiba SDD. “We made improvements to push the capacity, increase shock resistance and lower power consumption and noise. The resulting drive is perfect for integration in high spec portable PCs and other portable devices. Our strategy is to create the technologies and products that make a reality of ubiquitous computing and we are sure the MK1031GAS makes a valuable contribution to that.”

Toshiba achieved the world’s first 100GB 2.5-inch HDD by establishing a new benchmark for areal density: 80-gigabits of data per square inch. The key to achieving this was replacing the Pico Sliders attached to the drive’s heads, which maintain the appropriate distance from the disk during read and write operations, with Femto Sliders that are 35 percent smaller and much lighter. Advances were also achieved in the thin-film technology for both the head and media.

The new drive’s operating shock resistance of 325G (2msec) is 50 percent higher than in Toshiba’s current 2.5-inch HDD, due to the employment of smaller, lighter Femto Sliders in combination with a lighter head-suspension and head arm.

Power consumption of the MK1031GAS is approximately 20 percent lower on average than the company’s current drive(a) due to pulse width modulation (PWM) that controls disk rotation speed by switching the power supply to the spindle motor on and off at a controlled frequency. A DC-DC converter is also used in the power unit.

The new drive is the latest addition to Toshiba’s full line of mobile hard disk drives, providing customers with every key capacity point. Toshiba’s line of drives include 2.5-inch HDDs available in 15GB/20GB/30GB/40GB/60GB/80GB and 100GB capacities and 1.8-inch HDDs available in 10GB/15GB/20GB/30GB and 40GB capacities. Toshiba is also currently developing 0.85-inch HDDs in 2GB and 4GB capacities.
