Review on Memory Card Kingston microSDXC 128 GB Class 10, V30, A2, UHS-I U3, R/W 170/90 MB/s by Boyan Dimitrov ᠌

At first, when I saw a 40 MB read write, I thought about sending this Fake back, but then it came out that in fat32 the speed reaches 80 (shown on the screen), and even in the first few seconds on custom firmware I managed to get 100+ for writing to exfat, possibly thanks to the cache. So, I decided to keep the Fake for a little while longer. As a consequence, the exfat speed falls to approximately 40, or even lower. Those. It is to your advantage to have a reading and writing speed that is fifty percent of that which is advertised. Perhaps it's only happening on my phone.
