Review on SanDisk Samsung SDSQUAR 256G GN6MA Everything Stromboli Computer Accessories & Peripherals in Memory Cards by Adam Clemons

I went with a Sandisk Ultra 400GB Micro SD card instead of a 512 for only a $20 difference. After realizing that the memory only has 366 gigabytes of actual workspace. 34 giga is not good. I never had the declared 100 Mb/s. Only 32.5 Mbps. Not to mention that I own one of the latest HP desktops with a Ryzen 5 AMD processor. And 16GB of RAM. I doubt that Sandisk Extreme is faster. I recommend you do your homework when considering these higher capacity SD cards. Lexar is another promising brand. I just wanted to give this review. Many Thanks
