Lexar Professional 2000x SDHC/SDXC UHS-II cards let you quickly capture and transfer high-quality photos and extended lengths of Full-HD and cinema-quality 4K video, with a read transfer speed up to 300MB/s (2000x).
Impeccable snag-free 4k recording of heavy codec video. To new to talk about reliability. Only reference I got is similar cards from the same manufacturer and none have ever failed.
