[0.1 lb] I installed it, Windows 10 recognized it, and it works as it should. Faster backup for my media files and keeps the workflow with my older PC still viable.

[0.1 lb] Funciona a la perfeccion. Gran velocidad a nuestra Mac Pro 2012 5,1

[0.1 lb] This does exactly what it says it will do, which is rare. I use it in an HP Z840. I was having power issues with my regular USB3 ports at the back and tried this to take some of the load off. I was concerned that I'd need an extra power source for this card or that it wouldn't work in my very bottom PCIe slot (which is only 2x1, but my only available slot). Worked immediately without any issues.

[0.1 lb] Easy to install and works seamlessly.  Made our venerable Mac Pro 2012 relevant again.

[0.1 lb] Just pug and play, very fast and I like the services that Sonnet have.

[0.1 lb] Worked on my PC, just plugged it in, no issues. I didn't check speeds, but downloading a XQD card went very quickly!

[0.1 lb] My mid-2010 Mac Pro is aging. That, and my ext. backup drives, only have FW800 and USB2. So, I bought this PCIe card and two USB-C external drives to backup all my stuff and futureproof me. Installing this card was an absolute breeze. (There's a great YouTube how-to.) Then, I backed up to one of my new USB-C drives and it was smooth and seamless. I'm very happy! Something I learned though, that is NOT the fault of the card, is that my Mac's ROM only recognizes a USB-C PCIe card after boot up, so you can't boot, say, a clone of your internal drive with it. That may be important to know for some people. Also, I thought I might see much faster transfer speeds, but the speeds were just a little faster than FW800. Could be because my new USB-C drives are only 540rpm, I'm not sure. So maybe don't expect dazzling speed improvements. I highly recommend this card.

[0.1 lb] I ordered this Allegro USB 3.1-C type card because my PC was damaged during a no-warning fire safety power shut-off back in October here in California which caused a surge straight through my APC backup/surge protector. This resulted in a damaged front audio and USB port unit through the main switch to my computer case which connects directly to the motherboard. Therefore all the USB ports on the front of the case and on the back I/O of the motherboard became non-functional. This card, attached to the motherboard, bypasses the USB-C port on the back so that I can temporarily use it for USB-C connections until a new USB/audio/switch unit arrives from Germany for my Be Quiet! 800 case. Fortunately, it is still under warranty, and Be Quiet! offered to replace the unit free of charge. However, the Allegro card only works in PCI-E 3.0 or higher slots. It will NOT fit in PCI-E 16 express (the interface is too wide). I tried it in a PCI-E 2.0 slot and it will not function in it at all. Be sure that you have the right configuration or it will not work. It has two USB-C ports. Therefore, with the right cables, I am also able to route it to a four-port hub for other USB input needs such as thumb drives. This adapter is similar in writing speed to the original USB-C port on the I/O from the motherboard. This, with a four port USB 3.0 card connected to the PCI-E express gives me enough latitude to plug in all of my peripherals until final repairs are made. When that happens I will use it in another older PC build which does not have USB-C capability. I have tried it in that PC and it works very well and fast.

[0.1 lb] Installed this in an OptiPlex 7710 SFF computer in the X4 slot. The Win11 operating system detected it and it showed up in the Device Manager as expected.

[0.1 lb] I am extremely happy with this PCIe card which added two USB 3.2 Type C ports on the back panel of my Z590 motherboard. It appears to be well made and fit perfectly in the bottom expansion slot, which is configured as 16x4. It requires a longer slot than the extremely short ones which are called 1x1 I believe. The instructions aren't clear on this or much else, they basically say put the card in a slot that fits and it should work. And that's true, apparently. Still a little more useful information would probably be helpful for people with installation problems.
I had no problems at all and using a USB C to C cable I'm getting consistent transfer speeds over 500 MB/Sec. Surprisingly, this speed is unchanged using a USB C to A cable, as long as it's the correct cable for USB 3.1 or 3.2. The older USB 3.0 cables don't work properly and using the wrong cable reduced the data transfer speed from 520 MB/sec to 30 MB/sec. So, you need the correct cables. In most cases, the read or write speed of the devices being used will be the speed limiting factor, rather than the port itself. For example, my 7200 RPM NAS drives deliver about 220 MB/Sec, so that's all you're going to get through this port. A 2.5 inch SATA SSD will deliver about 550 MB/sec, so this port will just about keep up with that. NVME drives running at over 3000 MB/Sec will still be limited to around 500 by the port or associated cables.
