@YSeekingAlpha There is no need for such a fast microSD on a smartphone. 4K recording (which M4 doesn't support) requires at least class 10 microSD. So you are fine with class 10,perhaps UHS I.
Not true at all, any storage divise speed is not only quatified by its sutaind speed, more importaint is the random access, specially with the M4 that only got 4GB free space, you wane have fast random access to your card, something the the faster microSD cards can diliver.
@Even if i had a old PC with only SATA 150, i still would notice if i use a new SATA 600 SSD @150MB/s speed, then a old SATA 150 SSD.
As the new one would still with random (app) data use the USH-I to the max, ware a microSD that has the same max speed as the bus of the M4, has a verry low data transfer whith random data.
Its just like with a car whit lots of HP, drives faster and easier then one with lot less, even tho bot are limmited by the same speed limit of the used road, ofc if your USH-I bus is not a limiting factor, you can transfer video files a lot quicker to your PC, but how often do you do that, for me random accedss for App speed is just as important.
