I have a late 2018 MacBook Pro I9 Vega 20. I do a lot of FCPX video editing and use a external Samsung SSD via usb. Lately I had been noticing a lot of stutter and rolling when editing. I always use the right side usb ports for it. So i decided to do a disc speed test and it was only 40-45. I thought well my drive is going bad so I took it into my main office to use on my main I Mac. Speed test using same cord and drive was 900-975. I then went back to my MacBook Pro and plugged into the left side ports...... and to my surprise 900-975. Back to the right and back to 40-45. Looking in system profile when I plug into the right side the drive shows up to 480. On the left side its up to 10 Gig. Lucky I still have apple care on it and can call apple but wanted to see if anyone had any ideas on what has happened?
