The SanDisk UHS-I microSDXC 512GB Extreme U3 A2 is a microSD memory card that’s designed for capturing both still and video files, including 4K UHD and Full HD. Key features include:
UHS Speed Class 3 rating
Fast read and write speeds
microSD adapter included
Not a standard SD card!
UHS Speed Class 3 Rated. This UHS Speed Class 3 rating allows capture of uninterrupted, cinema-quality 4K, 3D, and Full HD video at a minimum sustained write speed of 30 MB/s. If you’re shooting 4K video with a camera that uses the microSD format, this is what you want.
190MB/s Read and 130MB/s Write. The fast read and write speeds allow large amounts of data to be transferred to and from the card with minimal bottleneck. Additionally, the accelerated minimum sustained write speeds prevent dropouts and stuttering, making it well-suited for Full HD video recording.
microSD Adapter. This rental includes a microSD adapter that allows simple transfer of files in the universally friendly SD card format.
Not an SDXC Card. This is a microSDXC memory card. If you’re looking for a standard SDHC/XC memory card, click here.
While microSD memory cards can be used in cameras with a standard SD slot via the included adapter, we don’t recommend this workflow due to adapter instability. If you need standard SD media, click here.
Thanks to its Speed Class 3 rating, this card fully supports 4K video capture on GoPro camera models Hero4 and newer.
