I didn't realize the speed difference between my USB 2/3 XQD reader and old MacPro and the same card using USB-3/C on my MBP M-1. Much, much faster. The older system brings in 24MP images in about 5-7 at a time and the newer with much newer ports/card reader (something cheap from Amazon) brings in images 20-25 at a time.
Needless to say I now ingest, rate and sort my photos on the MBP and use the ancient MacPro for processing and crafting images in Photoshop which it still does well, but a bit slower for some things.
