Review: Better Than the Cheaper Competitor Cards - First I looked on the internet for reviews of different cards, and Allegro was at the top of the list. Do they require drivers or electrical hookups in the computer, etc, in order to function properly--no, Allegro doesn't. The important question for me is: can you really use 4 USB ports at one time with this card? Based on my experience (I have purchased 3 USB C 2 port cards, and 1 USB 4 port 3.2 card), the Allegro card is plug and play and doesn't require a driver or electrical cable hookup. And the card works properly: In one of my computers (HP z2 G9) I have two cards installed: USB C and USB 3.2 and there is no problem. Be careful of buying the cheapo cards!
Review: Plug & play for Mac Pro 2010 5,1 - It works! Excellent throughput. (Tested with Blackmagic Designs disk tester on all my devices.) Mac OS High Sierra. I had a USB 3.0 4-port that fail on me (Inateck) just like a previous reviewer. The ports stopped working AND creating some conflicts on native USB ports such as external devices (SD, portable drives, etc.) preventing them to mount. Extremely happy and relieve that Sonnet was easy to install. It fit snug in the PCI-E slots and the ports line are aligned better than the former card. I was able to fully plug in Lexar UHS-II SD card reader (~250MB/s). I put it in slot 4 to avoid blocking the GPU fan, and it did not interfere with the full size hard disk mounted to drive sled above it. I can’t attest for the durability at this point. Installed yesterday.

### ⭐⭐⭐⭐⭐ Fast, reliable
*by S***R on March 3, 2016*

I installed my Sonnet Allegro USB 3.0 card in a 2009 Mac Pro, running El Capitan. No third party drivers were needed. The card is working flawlessly, unlike two other brands cards I'd tried on earlier releases of OS X. Of course, I tested it for speed ...
