The SD Association has introduced a new Ultra High Speed Class 3 SD card format which is capable of supporting 4K video recording.
Recording and storing videos at 4K resolution has not actually gone mainstream. It is still a pretty expensive hobby and this is why it is mostly done by professionals with high budgets.
As the ultra HD quality is heading towards consumers with the help of cameras capable of recording movies at ultra HD resolution on the cheap and TVs ready to display such increased quality, the last piece of the puzzle is the SD card.
SD Association announces new SD card format that stores 4K videos
Currently, there are no conventional SD cards that can handle such a high amount of data. However, the SD Association is aiming to change that with the help of a new Ultra High Speed Class 3 SD card format that supports 4K2K video recording and a broad range of devices.
The SD Association has confirmed that the cards will be released in SDHC and SDXC types and will support consumer-level DSLR, mirrorless, camcorders, and video cameras.
Keeping everything on a single small SD card
The new SD card format will not increase the size of the storage cards therefore they will be backwards compatible with existing devices, regardless of whether they can capture 4K and 2K videos or not.
As the digital imaging world is evolving, the memory types must evolve as well and the UHS Speed Class 3 is the next step in the SD card development, stated the SD Association President, Brian Kumagai.
The upcoming SDXC and SDHC cards will provide enough room to store all types of documents on a tiny storage device, which can only help photographers and videographers save money and time.
Writing speeds of up to 30MBs are more than enough for consumer-level 4K video cameras
The next-generation 4K-ready SD cards will bear the UHS-II and U3 symbols on them. This means that they will support transfer speeds of up to 312 Megabytes per second or and 30MBs writing speeds.
This means that the SD cards will only work with some 4K video recording cameras, as the high-end models require much faster speeds. Either way, they should be enough for the Panasonic GH4 and other consumer-level cameras that will be released in the near future.
