Review on 📷 High-Speed 256GB Micro SD Card with SD Card Adapter - Class 10 for Camera, Phone, Computer, Nintendo Switch, Dash Cam, Surveillance, Drone... by Ayush Bonuccelli

My first order was for two (2) 256GB cards and one of the cards was only 128GB. I played around with the 256GB card before placing a replacement order. I tried burning multiple Raspberry Pi images onto the card and was only able to fully boot the card once out of five attempts. I sent both cards for exchange. A few days later I received two 256GB cards. I've played with one of the cards, tried writing a 128GB image to it, tried writing a 16GB image to it, and tried writing a 64GB image to it. All three attempts had problems. These are the same images I wrote onto the Samsung EVO card with no problems. At one point the card wouldn't even boot and there was just a yellow lightning bolt in the top right corner indicating either incompatible boot software or a power warning. I will try another map and update this review if needed.
