Sony SR-64UY3A/GT High Speed 64GB Class 10 Micro SDXC UHS-I Memory Card up to 90MB/s with Adapter

hi everyone this is dirk thanks so much for tuning in this is another unsponsored video i purchased with my own money about 14 different sd cards from all major brands and we want to focus on the fastest cards in the market to see how they really perform in relation to the advertised speed i'm using a pro grade uh s2 usb 3.2 sd card reader and i'll connect it directly to my msi ge75 radar which is equipped with usb 3.2 ports we'll read it out through crystaldiskmark which is a free program and i'll put a download link in the description below now all the different letters and logos on the sd cards mean pretty much the same thing class 10 is the same like a u1 or v10 it stands for a minimum sequential writing speed of 10 megabyte per second now if an sd card would support a minimum sequential writing speed of 60 megabytes per second the manufacturer would print a v60 u3 and class 10 logo
