The guardians of the SD memory card specification announced version 3.0 of the technology less than a year ago, but that hasn’t stopped them talking up version 4.0 already..
SD 4.0 cards will have ten pins, one of which will handle the serialised data stream that runs at 300MB/s. The remainder will operate in parallel to deliver backwards compatibility. The size and shape of the card will not change.
Wow, with up to 2TB max size, and 300MB/s were talking about a huge step in technology. Toshiba had the first 64GB SDXC card(60MB Read/ 35MB Write), check out the story here. Once SDXC devices start popping up around the globe, well be looking at more storage, better quality video, bigger and better pictures from cameras, the possibilities are endless. Need more storage for that laptop? Does it have an SDXC slot? just pop in an extra 128GB(doesn’t exist at the moment) and your good to go.
I myself might hold onto my 2GB cards for now, until these cards become mainstream, as each new size gets announced, the price drops, and thats good for everyone!
