I have it connected USB-C to USB-C with the included cable. I think my computer must have the slower USB hub even though the advertisement when I bought it made it seem like it is the fast version of USB-C. I remember reading (unfortunately a while after I purchased my computer) that USB-C is sometimes just the C type port but connected to the slower hub.
Here is my USB information from System Information and also from a command I ran:

I don't have another computer with a true/confirmed USB-C port/hub to test this new portable SSD, so I am trying to determine if the low speed is a problem with the portable SSD or my computer. The earlier version of Sandisk Extreme SSD -- the non-Pro version -- was rated for speeds higher than what I am able to get. The Extreme Pro is supposed to be twice the non-Pro version -- up to 1,050 MB/s -- and in benchmark videos shows real world speeds in the 700s and 800s.
One other minor question. When I plugged the SSD in and checked the properties, the filesystem was listed as "FUSE", which I had never seen before. I read that Fuse is "bridge" to the filesystem to help with compatibility. Any chance that could be slowing it down? Any reason to reformat the drive?
I expect the reason for the slower than anticipated speed is that I don't actually have the USB-C 3.1 I thought I had, and it actually runs 3.0. Can anybody confirm that from the system information I posted? Thanks in advance for any help!
