Which one of these SanDisk Ultra SD cards has faster WRITE speed?

Hi all,


I'd like to know how to determine write speed of SanDisk SD cards. For example, I am trying to find out which of these two SD cards has faster write speed:


#1: SANDISK, Micro SDHC Ultra Android, 16GB, SDSQUAR-016G-GN6MA, class 10 UHS-I


#2: SANDISK, Micro SDHC Ultra, 16GB, SDSQUNC-016G-GN6MA, class 10 UHS-I


I can see #02 has write speed of 30 MB/s but write speed is not specified for the card #01.


SanDisk's SD card specifications mention C10, U1 and A1 but Speed Class Standard table mentions UHS-I, UHS-III, V6, V10, V30, V60 and V90 and it does not menstio A1!?


Can someone please explain how can I know write speed in MB/s of the card SDSQUAR-016G-GN6MA or any other SanDisk SD card?
