Toshiba Corporation has announced a 1.8-inch drive that offers a storage capacity of 100 gigabytes, the largest capacity yet achieved in this class of HDD. The new drive, MK1011GAH, employs perpendicular magnetic recording (PMR) technology and an improved error correction code.
The areal density for this 1.8-inch HDD is 240.8 megabits per square millimeter (155.3 gigabits per square inch). Toshiba will start mass production of this new drive from January 2007. The drive measures 54.0 × 71.0 × 8.0 mm and weighs 59g.
The company says packing larger data capacities into small form factor HDD is a must to support continued advances in the notebook PC market and to meet growing demand for personal digital media supporting high capacity audio and video applications.
Toshiba has also improved power consumption to 0.003W/GB. The new drive also complies with the EU's RoHS directive, which came into force in July 2006.
With 2 platters and 4 heads, MK1011GAH offers an average seek time of 15m sec and data transfer rate of up to 100MB/sec at 4,200rpm. The device uses the ATA-7 (LIF connector) interface.
