World’s highest areal density in a 2.5-Inch HDD reached at one terabit per square inch

Toshiba has announced it has achieved an areal density of one terabit per square inch (1Tbit/ in2) within a 2.5-inch client hard disk drive (HDD). This newest disk drive innovation delivers 3TB capacity using a 750GB per platter in a 15mm 2.5-inch HDD and increases areal density over Toshiba’s prior generation of client HDDs by 40 percent. The high areal density HDDs will be available in new products shipping later this year, says the company.
