If you’re not happy with the transfer rates of your current SD cards, you’ll be happy to know that they are once again getting a speed increase. The new standard, currently bearing the incredibly boring name of ‘Specification Version 4.00’, is set to launch next spring. As of now, the maximum transfer rate is 104Mbyte/s. The 4.00 spec will effectively triple that speed.
The new standard will require extra pins in order to achieve the greater speed. (The above chart is especially descriptive regarding this.) Thankfully the newer cards will still work in older devices, albeit at a slower speed. I’m still waiting to see a 2TB card, which has been the theoretical maximum size since the SDXC standard was announced earlier this year.
