By using the function, it is possible to improve memory usage ratio considerably. SD Standard for Video Recording There are wide discrepancies in memory access speed depending on the SD memory card manufacturer and brand. But as the data demands and transfer speeds required for video became more commonplace, a new option was required. UHS-II was soon developed, offering much faster read and write speeds. But the demands of 4K put a lot of pressure on your memory card.

Do you have the right memory card for the job? However, there is still another way to tell the two formats apart in a hurry. Flip the card over.
