Either not class 10 or defective
1 of 1 found this helpful I've bought this Micro SD card thinking it would be faster than my old memory card but it turns out this is even slower than the Sandisk Class 4 I had. Best speed I could achieve was around 4.5MB/s write speed and 10MB/s read speed.
I'm using it on a new phone so that's not the problem, and I've tested a real class 10 MicroSD on it before and faster speeds are certainly achievable. Despite the slow speed it does seem to be working properly.
