Review on 💾 Kingston Canvas Go! Plus microSDXC 256 GB: Class 10, V30, A2, UHS-I U3, R/W 170/90 MB/s with SD Adapter - Unbeatable Storage Performance! by Petar Velichkov ᠌

I almost sent this Fake back when I noticed a 40 MB read/write, but it turns out that in fat32 the speed exceeds 80 (as seen on the screen), and in the first few seconds on custom firmware I got 100+ when writing to exfat (likely due to the cache). Thus, the exfat speed is reduced to around 40, and sometimes even lower. Those. Half the stated pace in both reading and writing is sufficient. Perhaps it's a mobile device issue.
