I'm having a very similiar problem. I won't get started in my RAID enclosure issues, BUT my external drives that ran at 80/90MB/s on 10.12.4 are only running at 40MB's now. As a pro video editor thats unacceptable. My Thunderbolt drives that ran at 220MB/s are down to 180MB/s


My RAID used to run at 250MB/s via USB on my old MacPro and now refuses to run via USB at all on my $8000 iMac Pro (10.13.3) Via firewire and adapters it's down to 20MB/s.


This is all on Apple and is beyond unacceptable.

Cool, thanks for the link. I tried actually talking to them (in a very calm and reasonable tone) more about my issue and what I found with it working but I got transferred to a dead extension on 2 separate occasions. I asked to speak with the person who was in charge of my case as well and got transferred to another dead extension. I feel like I touched on a nerve and the more I look through the depths of the internet I'm finding not only USB issues but USB HW RAID issues with 10.13 from a lot of folks in my situation.


Anyways, thanks for the link. I'll email them in hopes this gets addressed.
