From PC World: A new class of SD cards that can record and access 4K and 8K video much more quickly is on its way later this year for devices like cameras, smartphones and VR headsets.
The SD cards use a new SD 5.0 standard that was announced Wednesday. They’ll allow users to record and access multiple 4K video files simultaneously, while current SD cards can handle only one 4K file at a time.
The cards have a special controller to handle the faster recording and extraction of 4K and 8K video, but the cards will still be compatible with existing SD card slots.
While 8K is still some way off, 4K adoption is growing. 4K TVs dominated this year’s CES, and laptops with 4K screens are slowly appearing. Some smartphones can record 4K video too.
The faster SD cards could be out by spring or soon after, said Brian Kumagai, president of the SD Association.
