April 28, 2004 (TOKYO) -- Toshiba Corp introduced a new 100GB 2.5-inch hard-disk drive (HDD) MK1031GAS, with a height of just 9.5mm.

"We are delighted to announce the world's highest capacity 2.5-inch HDD," said Seiji Kawagoe, senior manager of the HDD Product Planning Department, Storage Device Division, at Toshiba's Digital Media Network Company. "We made improvements to push the capacity, increase shock resistance and to lower power consumption and noise."

Toshiba achieved the world's first 100GB 2.5-inch HDD by establishing a new benchmark for its specific type of density: 80Gbit of data per square inch.

The key to achieving this capacity was replacing the Pico Sliders attached to the drive's heads, and which maintain the appropriate distance from the disk during read and write operations, with Femto Sliders that are 35% smaller and much lighter. Advances were also achieved in the thin-film technology for both the head and the platter.

The new drive's shock resistance of 3,185 m/s2 (325G, 2ms) is 50% higher than in Toshiba's current 80GB 2.5-inch HDD MK8025GAS, due to employment of the smaller, lighter Femto Sliders in combination with a lighter head-suspension and head arm.

Power consumption of the MK1031GAS is approximately 20% lower on average than the company's current drive 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 certain frequency.

Low noise operation, as low as 21dB in an idle state, is achieved by an optimized sinusoidal waveform to control the operational current of the spindle motor.

Samples of the MK1031GAS will be available in May.

Era interessante saber o numero de rotações do disco, mas mesmo assim 100Gb é mt bom mesmo.

FreakDaHouse, não contes com muitas rotações!
Eu tenho um Toshiba MK8021GAS (80Gb a 4200rpm) que é um bocado lento, são poucas cabeças para tanto Gb!!! Aliás que eu tenha visto a Toshiba não anuncia no site nenhum disco a 7200rpm...
