Toshiba has made a technology advancement in the areal density of their platters used in 2.5" client hard drives. Toshiba has managed to hit one terabit per square inch (1Tbit/in2) which translates to 750GB per drive platter. In a four-platter 15mm platform, that's 3TB per drive, which is a 40% boost over Toshiba's highest capacity drive in that class.

Toshiba provided very few other details on this advancement other than the technology is standard Perpendicular Magnetic Recording (PMR) as opposed to the newer Shingled Magnetic Recording (SMR) drives that are starting to come to market. It's likely that this latest density gain is near the last for Toshiba's PMR drives however as SMR can drive dramatic capacity gains, albeit at the cost of performance.
Toshiba’s new high density HDDs will be available later this year, most likely starting out in branded (direct attached) enclosures.
