Toshiba America Storage Device Division has expanded its 5,400 RPM 2.5-inch mobile HDD product line with the addition of two new product families, MK7559GSXP HDD with 9.5 millimeter-high, two-platter design and capacity of 750GB; and three-platter 12.5-millimeter-high platform MKxx59GSM series that offers 750GB and 1TB of storage.
Toshiba said that it has implemented Advanced Sector Format technology in both the families and were developed with the combined engineering resources from the integration of Fujitsu’s HDD business.

The 482 Gb/in^2 areal density MKxx59GSM supports a buffer memory of 8MB. It also features Serial ATA Revision 2.6 / ATA-8; and supports 1,196Mbps media transfer rate.

Toshiba’s MKxx59GSM series and MK7559GSXP drives are scheduled to ship to PC manufacturers and distributors in the second and third quarters of 2010, respectively. Design samples of the MKxx59GSM are currently available to system manufacturers, followed by samples of the MK7559GSXP in April.
