Toshiba has announced a new model into its line up of NAND-flash-based solid state drives with the industry's first 2.5-inch 512GB SSD.

The drive is based on Tosh's 43 nanometer Multi-Level Cell NAND and claims to offer a high level of performance and endurance for use in notebooks as well as gaming and home entertainment systems.

It has a maximum sequential read speed of 240MB per second and maximum sequential write speed of 200MBps meaning faster boot and application loading times. The drive also offers AES data encryption to prevent unauthorized data access.

The drive will be showcased at CES, and should go into mass production later in 2009 meaning that ultraportable SSD-packing computers, such as the MacBook Air or the Lenovo X300 may offer the larger capacity towards the end of the year.
