Toshiba Announces 750GB and 1TB Laptop Hard Drives

Toshiba today announced two additions to its 5,400 RPM line of 2.5-inch HDDs featuring industry-leading storage capacities.

In the standard 9.5 millimeter- high, two-platter design, the MK7559GSXP HDD incorporates both the industry’s highest areal density and capacity at 750GB. Toshiba also introduced a new three-platter 12.5-millimeter-high platform with the MKxx59GSM series, which offers 750GB and 1TB of storage. These capacity points were predominantly supported by larger form factor 3.5-inch HDDs until the introduction of high-end 2.5-inch solutions, providing low-power, space-saving opportunities to system manufacturers looking to differentiate or update their products.

To deliver these next-generation storage capacities, Toshiba has implemented Advanced Sector Format technology in both families. This technology uses 4K byte-per-sector formatting and improved error-correcting code (ECC) functions, providing maximum data integrity and making efficient use of the storage surface area. Toshiba is guiding efforts to ease industry transition to the advanced 4K byte-per-sector format, while continuing to provide a full line of mobile HDDs, including models that support the legacy 512 byte-per-sector configuration.


“Toshiba continues to lead in integrating state-of-the-art technologies such as 4K byte- per-sector formatting to drive capacity increases and help system manufacturers succeed in their markets,” said Maciek Brzeski, vice president of marketing at Toshiba Storage Device Division. “Since the introduction of our first 4K byte-per-sector offering on a 1.8-inch HDD in 2007, we have leveraged our miniaturization expertise to perfect this technology, balancing storage advancements and reliability with solid performance. As a result, Toshiba can deliver performance benefits with high capacity drives using the 4K byte-per-sector implementation by working with product manufacturers to maintain compatibility with the host device’s operating system and software packages.”
