Item is easy to install and works as advertised. The only issue is it requires an X4 PCIe slot and the machine I installed it in has only one X16 and two X1 slots. I'm using it for high-speed external SSD drives for additional volatile storage.

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.

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.

I needed this because the USB-C output on my motherboard did not supply enough power to charge my Oculus Quest 2 while playing and I would find myself running out of battery life at the worst times. I play DCS world so I will be on for long stretches of time. This card solved that problem, regardless of what percent battery my Quest 2 is when I start playing, whenever I stop playing, it is always at 100%. Problem solved...uh....mostly......because one downside was in game I was having major stuttering or jitters to the point it was almost unplayable and that didn't happen with the onboard USB-C so I knew it was this card.I was about to return this card but then I read that X570 Ryzen motherboards have issues with USB but a bios fix was coming. I have a X570 TUF Pro and I downloaded the latest bios that addresses some of the USB issues (bios dated Mar 22, 2021). Installed that and now I get jitters only once in a while, not enough to be distracting. The bios update seemed to have fixed it mostly and now my quest stays charged during gameplay that I don't have to worry about it so I am keeping this card and it has worked for my needs. There is supposed to be another x570 bios update coming for my motherboard so hopefully the new release will completely solve my jittering, but if not I am ok. BTW make sure the card is plugged to your power source using the SATA cable if you want to keep your Quest 2 charged.

Installed easily into a Dell desktop with a free PCIe slot. Gave the user two more USB-C ports and they are faster with v3.2. Installed with no hassle and drivers were found automatically by Windows 11.

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? WorksHD? Fast.Charging?* Sure does... *as long as you provide SATA power, but you already knew that ;)

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.

My "brand" PC came standard with only 1 USB-C port. So, adding 2 more with the expertise and performance of StarTech.com's 10Gbps PCI Express 3.0 x4 Adapter is a very welcome USB-C expansion solution!

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.

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!

Si al igual que yo tienes un Mac Pro 4.1 → 5.1 con macOS Catalina solo decir que funciona de maravilla. Instalación rápida sin necesidad de instalar ningún driver.

Ich nutze die Karte unter Linux. Sie funktioniert problemlos, ohne irgendwelche Treiber installieren zu müssen.
