I was originally using the cable that came with the drive. At some point I kept plugging it my Macs and sometimes it would go slow speed USB, and sometimes it would go to 10. I was plugging it into a CalDigit/OWC hub (depending on the Mac) and directly to the machine. After realizing what was happening I just picked up a 20gbps (or 40, I can't remember) cable off of amazon and the problem went away.
