Review on Enhanced Performance Lexar Professional 1000x 64GB microSDXC UHS-II Card (LSDMI64GCBNA1000A) by Tutan Hesch

Ultra 30 action camera. I recorded several videos at 4K/30 FPS (the highest resolution the camera can transmit) without any problems. I also ran some tests with Ubuntu (dd, gnome-disk, iometer and bonnie++) and it has a very fast read speed (+100MB/s) but not so fast write speed. I first bought a Samsung Pro Plus 128GB MicroSDXC memory card (MB-MD128DA/AM) which had the best write test, but in the end what really counts is whether the card can match the performance of the camera and I'm in for it corrupted videos and/or corrupted G-Metrix all the time so I returned it. Before sending it back, I checked the card for damage, did many tests and the card passed all of them. I still don't know why there are so many corrupted files (some videos won't play and I can't import G-Metrix). I also like the USB adapter, it performs much better than the SD adapter that comes with most other brands, it fits into a regular USB port (no card reader needed) and is easy to plug in. use. It also works with other brands of Micro SD.
