Their latest offering that came across our desk is the Ultra Plus line being powered by the Marvell 88SS9175 controller and SanDisk’s own 19nm NAND. The 6Gbps interfaced drives are marketed towards the both the desktop and mobile computing crowds with promises of strong performance, high reliability and power efficiency. It comes standard in the 7mm, 2.5″ form factor so it should be good to go for most Ultrabooks as well.
