Review on 📸 Gigastone Micro SD Card 32GB - High Performance Memory for Video Cameras, Wyze Cam, Security Camera, Roku Full HD Recording - Class 10, up to 90MB/s Speed by Pushkraj Barton

I bought a 512GB gigastone microSDXC card and was a bit skeptical but that's the real deal. Passed tests with FAKEFLASHTEST v1.1.1 and H2testw. The card was tested at 98MB/s reading and 59MB/s writing in Crystal Disk Mark v8.0, making it an average speed, although slower to write than the manufacturer's advertised speed. 80MB/s. This was the only test using a single card reader on a specific YMMV card. For buying a legitimate, high-capacity, "normal" speed card, this is one of the best options.
