The MK7559GSXP is the first 2.5", 9.5mm drive to hold 750GB. As such, it can provide the capacity expected of a desktop hard drive but fit into thin-and-light notebooks like the MacBook Pro as well as all-in-one desktops and digital media hubs.
Despite having about 17 percent more capacity, the new SATA II drive consumes about 14 percent less power than the 640GB drive it's set to replace and could extend the theoretical battery life. It spins at just 5,400RPM, but its very high density, two-platter design may compensate for the perceived drop in access speed.
In tandem with the thin drive, Toshiba is rolling out the MKxx59GSM line, which brings 750GB and 1TB drives but in a taller three-platter, 12.5mm (0.49in) profile more suited to desktop replacement notebooks and other computers where thinness isn't an absolute priority. Both rotate at the same speed but is slightly less energy-efficient.
All three of the disks are due to start sampling for system builders in April and should enter mass production soon afterwards.
