SD Card Speed Leap

For a long time the read/write transfer rates for SD memory cards has lagged behind CF cards.  That has now changed.  SanDisk’s new SDHC/SDXC Extreme Pro card with UHS-II sets a new standard of up to 280MB/s read and 250MB/s write.  Part of what has pushed this technological advance is the advent of 4K video, but it will make a difference for still shooters too as long as your camera is designed to take advantage of the card’s protocols.  At the moment, it seems Fujifilm’s new X-T1 may be the first camera to take advantage of this.  More to follow, no doubt.
