From the photo, the 2TB microSD card appears to be UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) which correspond to a minimum of 30 MB/s transfer speed [1]. This is good but still pales in comparison with external SSDs with >1,000 MB/s transfer speeds [2] and internal SSDs with >7,000 MB/s transfer speeds [3].
