Report on Low-Cost Vantec USB 3.0 PCI-e Card (Mac Pro 5,1, macOS 10.13)
"USB 3.0 card success with Mac Pro 5,1
I got the itch to visit my local MicroCenter and found a Vantec 4-Port USB 3.0 PCI-E card for $23.

It came with the SATA power to molex adapter. Since I don't have a 4th drive in my Mac Pro it was convenient to hook this card up with that power port. (Were you already using the 2nd Optical Drive bay?) I had to break off one of the tabs on the SATA power connector, but it fit nicely.

MacOS 10.13 beta build 17B46a recognizes the card fine, and I have an older Hitachi Touro 4TB USB 3 drive hooked up to it for time machine backups. I get 158MB/s write and 160MB/s read off that drive and the USB 3.0 card.

I can't speak to how reliable it will be but I was certainly surprised with the ease and performance of the card.
Cheers, John W."

Thanks John. Let me know if you update High Sierra (to non-beta) without any issues.
A reader asked if the Mac Pro would sleep with a USB device connected to this card. He's using a 2008 Mac Pro, didn't specify OS X version but said if anything is connected to his USB 3.0 card the Mac Pro won't sleep.
"Are there any updates on Sleep support with the USB card?
I've installed a USB 3.0 card in my Mac Pro 3,1 however if any USB device is attached the machine will immediately wake when put to sleep. This has influenced which devices I connect to which ports.
If this card doesn't share this problem I'd love to know.

What card brand/model and OS X version are you using?
Can you unmount the USB device before putting the Mac Pro to sleep? (If so does that help?)
