Review on Amplim Extreme High Speed 512GB Micro SD Card - MicroSDXC U3 Class 10 V30 📸 UHS-I TF with Adapter: Ideal for Nintendo Switch, GoPro Hero, Surface, Galaxy Phone, Camera Security, Tablet by Loren Jacobson

I know you'll never get the full 512GB but I have about 480GB so where did that 32GB actually go? I've had others from different brands that never used 32GB. I had a problem when trying to use it for the second or third time. I use it in my surface GO the first 1 or 2 times when it is recognized normally and I can write and read on it. Either the 2nd or 3rd time it wasn't seen by Surface GO. Reboot and everything is fine again. It hasn't happened since, but I hope it doesn't indicate an error waiting for it to happen when I load it with my data.
