Amazon Basics 128GB microSDXC Memory Card with Adapter for Smartphones, Drones, Cameras, Full HD, Read Speed Up to 200MB/s, 1-Pack

As others have said, the bottleneck is the GoPro itself. Pop the card into a proper card reader and you'll be much happier. L IMHO, it pays to spend a bit more money to get a card and reader combination that maximizes read speed. I recommend getting ones that support DDR2 transfer. It's the same trick used by DRAM controllers to speed up throughput: do two I/O transfers per clock cycle instead of just one. Instead of the usual 100 MB/s sustained reads, the theoretical maximum is 200 MB/s. SanDisk calls this "QuickFlow" technology, so make sure you buy the appropriate Extreme Pro (black and red) microSD cards and reader (B751 or C751 model number). Lexar, Kingston, ProGrade and other manufacturers probably have their own marketing name. Amazon Basics has their own now too, and it is surprisingly really good. Make sure you buy their black and gold cards, and the appropriate microSD card reader with the Type C plug. I routinely get about 160 MB/s reads when downloading footage. I typically amass about 30 GB of footage per day on my rides, and that takes 3-4 minutes. Card: https://a.co/d/050yJYsC Reader: https://a.co/d/056904sr
