Just Enough Extra USB C Space
It is exactly what I needed and works perfectly. Easy to install.

Oculus Quest 2's best friend
If you want to run a solid Oculus link with VR and be able to power it while you use it. You gotta get this card. I was trying to get away with not buying one and just charge my headset and plug it into a USB power jack and see how long it'll last. It ended up running out of battery in the middle of gaming and panicking to figure out how to rejoin the group was a challenge as I would have to plug my headset into the wall and needed to run Air link which is highly unreliable in my location with lots of interference. I bought this card after much research and solid reviews and it did exactly what i needed! Plugged my headset cable directly into it and it reads it perfectly, quickly, and keeps it powered with no more down time! Love my VR set up now.

Labeled USB 3.1 Gen 2, not USB 3.2, but it's the same thing!
Since it's StarTech, I'm sure it's great. What I received was the "old" USB 3.1 card, NOT the 3.2 card. CHECK YOUR PACKAGE when it arrives to be sure you get the right one. UPDATE: after realizing that both USB 3.2 Gen 2 and 3.1 Gen 2 were 10 Gbps, I did some research and what I learned was surprising! "Technical Basis: USB 3.2 Gen 2 is a rebranding of the original USB 3.1 Gen 2 standard by the USB Implementers Forum (USB-IF) in 2017 to simplify the naming scheme and align it with the USB 3.2 specification." So, I'm retracting my earlier poor review and giving back five stars. I'll do some testing and update if I run into any problems, but otherwise this looks like a brand-new and typically solid StarTech product. It's the same thing - who knew. This is a good product at a good price. I just wish the sellers would update the listing to indicate that they're the same thing so when you receive it, you're not in the dark about why you got less than you thought you'd paid for!

No windows 10/11 support, still working for oculus
Installation only takes a minute if you know what you’re doing. If not just watch a YouTube video. First off, the manual makes it clear the drivers only support windows 7. If you attempt to download them, the file will not run. I bought this to charge my oculus quest 2 while playing steamVR through link. Device was recognized right away through the oculus software. Played for about 30 minutes and only saw a 1% decrease in battery life. Usually it would be down more as it seems to have a weak battery. It does look to be slowing down the usage of the battery but it isn’t holding 100%. I will update the review in the near future if I run into issues but cannot give 5 stars due to the lack of windows 10/11 support.

Works!
I think the speed is really good but I never really measured it with any official software. The transfer rate seems very quick between disk drives. I could not tell you the exact transfer rates I get because I have no idea if the rates I see are from the old hdd, the new ssd or the combination of everything. My point is this does the job and had no trouble setting it up. Quality was top notch. The value was expectedly within my range. I haven’t had to reach out to their support so that’s a good sign after a month of 24/7 usage. I downloaded the drivers but never had to use them because Windows 11 automatically detected this card. I do wish it had more ports, but the be fair so far I only used one of the two ports from the card. I’m just saying that it would be nice to future proof a bit.

Works, but is about 20% slower than the integrated one on the same motherboard.
I have a single Usb 3.2 Gen 2 port integrated on the motherboard. This was intended to augment that to 3. I did some throughput testing, and testing of super fast nvme drives on all ports. Every test I did shows the ports on this card at about 20% slower than the integrated port. It is, however, significantly faster than the 5gbps ports on the board, so it does work. Just don't expect that you'll get identical performance out of it. You'll likely take about a 20% performance hit on the ports like I did. I'm assuming this is due to the ASMedia controller chip it uses being inferior to some of the others.

It just works with no BS
If you know who Startech is, then you don't need this commentary. For those who don't, you buy this for the simple fact that it works and it does exactly what it says it will do. No BS, no driver issues, no worry about 'malware' or whatever keeps you up and night. I've tried other Amazon brands for different PCIE related cards and they NEVER work. This one was literally plug and play (AS IT SHOULD BE!!!!) VR? Works HD? Fast. Charging?* Sure does... *as long as you provide SATA power, but you already knew that ;)

Viene sin cable de alimentación, por lo que no puede usar velocidades USB 3.2. Compré esto para poder usar mi cámara como cámara web y transmitir en 4k. Sin alimentación externa, sólo permite una resolución de hasta 720p. Tampoco tengo idea de dónde comprar un cable de alimentación, ya que las instrucciones no son buenas.

Looking at the review it's a mixed bag of good and bad. For me it works as it should. Provides power to charge my oculus Quest 3. Installed on windows 11.

The built in port on my Dell XPS 8940 could not provide enough power to charge my iPad Air 5th Generation - resulting in a power surge error. The card was easy to install and my XPS had a spare SATA power cable that I used for the additional power required. This card solved my problem and does a perfect job - thank you StarTech!

Poco da dire, ho scelto questo prodotto poiché l'ho trovato citato in variati post sul forum dell'Oculus Quest. Mantiene la carica del suddetto attorno all'83-85% durante l'utilizzo; dopo nmila tentativi di far andare - di nuovo - l'usb c dalla scheda madre e un tentativo fallito con un'altra pci-e questa ha funzionato. Da ricordarsi che per questo serve collegare la scheda con un cavo sata direttamente al PSU!!
