No also i want to know that whats difference between in these two cards from same company and same extreme pro series which images i have posted above means 1st is uhs 1 and 2nd also uhs 1 but with v30?
The 'V30' designation is for the newer microSD cards optimized for video recording. V6 for 6MB/second, V30 for 30MB/second, V90 for 90MB/second, etc. Unless you're recording video at 4K (I don't even know if the S7 Edge supports it) you should be fine with a non-V30 card.
Go to this site and look at the 'SD speed class' chart for an easy explanation graphic:
https://www.sdcard.org/developers/overview/speed_class/
It means v30 have no more than 30mb/s write speed?
Or
V30 also have 90mb/s write speed but with video record at minimum 30mb/s advantage?
