Sandisk has a few new ExtremePro cards available in 128GB and 256GB. Just in case you felt 256GB sd cards weren't large enough or maybe you were just too lazy to swap it out with another, Sandisk is also making available a new Extreme Pro 512GB SDXC Card.
These new cards look familiar, but are different than previous Extreme Pro cards by raising the bar with a UHS Speed Class 3 (U3) rating. These new cards are listed via Adorama (click here).
