Buffalo Technologies has just released information on a new series of SD cards with built in USB connectivity. The RSDU cards will be available from mid-July in a variety of sizes. Details that have been provided show these will be available in 256MB, 512MB, 1Gb and 2 GB. Functionality will be like those of normal SD cards and this will be compatible with Windows Me/2000/XP and Mac OS X 10.1.2.

These will be useful for those people who use laptops or desktops and want less fuss by having fewer or no wires at all. There are no more details on data transfer speeds, or prices on release, or even if they will be initially globally available. We'll keep you posted.
