Sandisk 1TB Portable SSD (USB3.2, etc)...

I just went made and bought one of these. I was :-O-ed at its size, a mere 45mm x 95mm x 10mm. I tested it on 1.3 GB of pics and videos, and got about 230 MB/sec max. The package says expect up to 520 GB/sec, but I’m running USB3 only. However, a couple of internal drives in docks do reach 300+

Win Properties shows the file system is exFAT (which I think is not as efficient with space as NTFS). I checked that my Crucial 1TB SSD is NTFS.

Now the question is, should I leave it as that or should I change it to NTFS (and is it even advisable to do that)? I wonder if this device is just a couple of SD-type cards in a box(???)

There are two pics below.
