Toshiba
Storage Device Division has announced its reached the 200GB milestone for a
notebook drive. The 200GB 2.5-inch HDD, announced at the Computex exhibition in
Taipei is based
on Toshiba's second-generation PMR (Perpendicular Magnetic Recording) technology.
With what is claimed to be the world's
highest areal density at 178.8 gigabits per square inch and the highest
capacity in the standard 9.5mm mobile PC format the dual-platter MK2035GSS is
Toshiba's first PMR drive to incorporate tunnel magneto-resistive recording head
technology.
The SATA II drive weighs a diminutive 98
grams and features native command queuing to enable faster data transfer rates
and improved technical performance.
"As a leading partner for mobile PC
manufacturers, we've listened to our customers' needs for high-capacity storage
in a small form factor to enable the advanced multimedia applications and
enriched usage experience that consumers are demanding today," said Scott
Maccabe, vice president and general manager, Toshiba SDD.
"Our technology innovation in PMR
has laid the foundation for delivering the industry's highest capacity and
areal density in the standard mobile drive form factor. It's a win-win
combination for mobile PC manufacturers who want to differentiate their
offerings with features that attract high-end consumers."
Toshiba says it will start mass
production for the 2.5-inch drive in August this year.
