Review on ADATA 64GB microSDXC Class 10 UHS-I U1 R High-Speed SD Card - 50MB/s by Mateusz Czyta ᠌

The reason for the inadequate behavior of the card is not clear. If the jamb is on my part, then why not immediately, but after half a month? I noticed an interesting nuance - when recording a smart FHD video on this card, the bitrate of the video stream jumped to a stunning 60 Mbps, when I changed this buggy card to 32 gb klass 10, it was not possible to raise the video bitrate above 20 Mbps in any way. Those. It turns out that when recording a 1080p video, the smart itself determines the speed characteristics of the card and gives permission for an exorbitant bitrate? Replaced under warranty with another manufacturer. : another not entirely clear moment - the card was in FAT32 right after the purchase. In theory, all cards with a capacity of 64 GB and above should be formatted in exFAT at the factory. : By the way, according to the review above - indeed, UHS cards for 64Gb and above require certain subtleties when used in devices that officially support 32Gb. All these subtleties were observed by me with the second card of the same changed (special card reader and formatting software). The card lived, periodically glitching, in the phone for about a year. Then she died completely and irrevocably, without any possibility of recovering the data.
