The SD association announced a newUHS-III card standard. It allows up to 624 MB/sec transfer ratem which is ideal for 8K and 360 degree video recording. Here is the full original press text:

SD ASSOCIATION DOUBLES BUS INTERFACE SPEEDS WITH UHS-III

624 MB/sec transfer rate makes quick work of high-quality camera images,
360-degree, virtual reality and 4K and 8K video applications

Pacifico Yokohama, Japan — CP+ Camera and Photo Imaging Show Booth # G-16 —
Feb. 22, 2017 — The SD Association announced today UHS-III, doubling the fastest
SD memory card transfer rate up to 624 megabytes per second (MB/s). UHS-III faster
speeds help move large amounts of data generated by data-intense Gbps wireless
communication, 360-degree cameras, drones, 3D, 4K and 8K videos recorded on
SDXC and SDHC memory cards.Mirrorlessrumors.com
Immense storage capacities introduced with SDXC memory cards give users the ability
to take more pictures and make unique video features on the latest imaging devices.
Fast UHS bus interfaces help users manage that content more quickly. Since it is fully
backwards compatible, devices offering UHS-III bus interface will accept the billions of
existing SD memory cards in the market today.

“SD memory card capabilities continue to expand, paving the way for new and highly
anticipated imaging and video features, from virtual reality to 8K video,” said Brian
Kumagai, SDA president. “The SDA remains committed to supporting innovation by
consumer electronics manufacturers and to delivering the same performance and
interoperability consumers and professional users love about SD memory cards.”

The SDA released a visual mark to denote UHS-III SD memory cards for easy
matching with devices’ recommendation for the best SD memory card for optimal
performance.

The UHS-III high-speed interface signals are assigned to the second row of SD
memory card pins introduced with UHS-II. This newest bus transfer speed option will be
available in full-size SDHC and SDXC cards, as well as microSDHC and microSDXC
cards. It does not change the physical size or shape of the cards as the move from
UHS-II to UHS-III involves only a PHY change, allowing relatively easy and fast
upgrades of existing UHS-II products to UHS-III.

Both UHS-I and UHS-II make the robust storage specified for SDHC and SDXC
manageable and even more portable. Ultra High Speed was announced in June 2010
with UHS-I delivering top bus-interface speeds of 104 MB/sec, which was tripled to 312
MB/sec in UHS-II. UHS bus interfaces are backwards compatible and are exclusive to
SDXC and SDHC products. All UHS-equipped memory cards achieve greatest
performance when paired with corresponding UHS devices. SDXC and SDHC UHS-I
and UHS-II products are already in retail outlets around the world and supported by
leading camera manufacturers. You can read more about UHS on our website.
