Megabits per second and megabytes per second (MBps) can be easily confused because they look the same, and both show data transfer speed. Megabit is always expressed with a lowercase "b," and megabyte is always expressed with an uppercase "B." A byte is 8 bits. One megabyte per second is equal to 8 megabits per second.

Is UHS 1 or 3 better?

In simple terms, UHS-1 Class 1 has a min write speed of 10MB/s, and Class 3 has a min write speed of 30MB/s, and we're talking also here about increased sustained write speed. This is a significant difference, and especially critical when recording large amounts of data rapidly, as would be the case recording 4K video.
