Review on 💾 High-Speed Silicon Power 512GB Micro SD Card U3 - Compatible with Nintendo Switch, SDXC microSDXC Memory Card with Adapter by Patricia Jones

Received a 512GB version of the card for use in a Raspberry Pi game machine. After several hours of waiting for the image to trigger, I started having resizing issues on the first launch. It turns out that the card has a lot of GB less than 512 GB. It formats up to 463GB/497GB. Also, when testing sequential writes, I couldn't get speeds above 40MB/s, which is half of what's advertised. I don't know if I got a defective card or if Silicon Power just sells junk that doesn't match their ad.
