A couple of corrections for the text that you copied from Amazon.
UHS is not a "speed class". U3 is the speed class, and the U doesn't stand for UHS. UHS-I is the interface type, it specifies the standard type of micro-SD contacts. For comparison, UHS-II is faster, but has an additional row of contacts.
"Speed: Up to 200MB/s read and 140MB/s write speeds" - only when you use a special card reader made by SanDisk, which overclocks the interface faster than the UHS-I specification. On ordinary readers and in cameras, you will be limited by the interface to no more than 105MB/s.
