Lexar’s latest Secure Digital (SD) card, the Lexar Professional 400x SDXC UHS-I, adheres to the SDXC standard and stuffs 256GB of flash storage into its shell with the help of a 20 nanometer flash memory process. Targeted at professional photographers and videographers who shoot in full-frame resolution and 1080 HD video, the 256GB card guarantees a minimum read speed of 60 MB/S.

At $899.99 and available in October, Lexar’s card  is a worthy back-up solution for computers with an SD card slot.  Oh, and by the way, SDXC can theoretically hold 2TB worth of storage. So, in a few years, 256GB will be the norm and 2TB will be for the professionals.
