Toshiba readies slim 750GB notebook hard drive

Toshiba makes 1TB for thin-and-light portables

Toshiba moved notebook storage a significant step forward on Wednesday night by launching the MK7559GSXP. The 2.5-inch drive is the first to hold 750GB but reach the same 9.5mm (0.37in) height as most slimmer notebook hard drives. 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. Either rotates 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.

    Avoid! Do not even go there.

    I own a drive recovery business. Toshiba make the worst quality drives in the industry, period. Do not even CONSIDER it.

    I have a MBP 15" Unibody and I installed a WD 1 TB yesterday that was as thin as the Apple HD that was factory installed. Oops, sorry, 998.86 GB

    Maybe, I am missing something here.

    Ah, the life of technology...

    question for MizuInOz

    just curious -- was it the WD10TPVT (or EVT) that you installed? these are 12mm high and there are conflicting reports online about whether they fit into the 13/15" MBP unibody. Even on the OWC site, they claim it fits, then some posters say it doesn't, then other posters say it does. Would love to know, definitively, if it will fit my 13" MPB unibody. thanks!

    Toshiba "launched" a line of new drives in September which still aren't available; the MKxx56GSY series. I'm not holding my breath for this one.
