Review on 📸 [5-Yrs Free Data Recovery] Gigastone 512GB Micro SD Card - Ideal for Nintendo-Switch, GoPro, DJI, UHD Video - R/W up to 100/60 MB/s - UHS-I U3 A2 V30 C10 by Antonio Taveras

This card tests about 50MB/s write, 90+ MB/s read with Blackmagic Disk Speed Test but when used in Insta 360 One X , it fails 14-20 minutes when recording at "too slow speed". This camera records two files simultaneously at around 6MB/s each, but recording something else at the same time prevents the Gigastone from delivering the results it promised. After trying to contact customer service: no support available. They contacted me, asked what resolution I was recording the video in, then fell silent. A star. For the same money you can buy a solid brand.
