It's easy enough to find ultra-fast SD cards-if you've got the cash
The new microSD cards are the first to ever meet the UHS-II spec, which means they share the same performances figures as fully grown SD cards: 240MBps write speed and 260MBps read. That's a blistering 8 times faster writing than Toshiba's previous fastest microSD cards.
Those figures should mean that even small cameras and smartphones can shoot in burst mode-like pro hardware-and even recording 4K video should prove possible. It's worth noting, though, that not all devices will support the UHS-II standard, so it's worth checking before you buy. There's no word on price or availability yet, but when they do arrive, they'll be available in 32GB and 64GB forms. [Toshiba]
