Review on 💾 KEXIN Micro SD Card 16 GB 5 Pack - High Speed UHS-I Memory Cards, Class 10, C10, U1 by Anurak Grubb

This card was advertised as a U1 SD card (10MB/s write) but all three in my pack were rated at over 40MB/s write speeds tested ( tested with 100 MB). sequential writing with Crystaldiskmark ), which puts it in the U3 category. The reading speed exceeded 80 MB/s. This was probably one of the few times I've bought an inexpensive microSD card that actually turned out better than advertised. Results may vary depending on the item purchased.
