This is USB C and USB A (full size USB port). The description is confusing, it looks like USB C so it should be faster. But it's pretty slow, most of my cards were running at 5MB/s, try another reader. 40MB/s up to 80MB. Again in this adapter.5.5 MB. Same laptop, same file transfer, same port, the only difference is the adapter the card is in. Very comfortable with double head. I leave it just in case
