Review on SanDisk 64GB Class 10 UHS-I microSDXC Memory Card with SD Adapter, R/W Speeds up to 80/10 MB/s by Taufik ᠌

Initially, I bought a card as the main memory in a music player. He copes with his duties with a bang - there are no glitches, lags, freezes. The only disappointing thing is the speed. Tested several times in CristalDisk - gives out about 45-50 meters / s for reading, writing about 10-20. For a music flash drive, this is not critical, but for those who write videos in high resolution and with a high bitrate, this is a reason to doubt the expediency of the purchase.
