StarTechcom 1-Port USB 3.2 Gen 2x2 PCIe Card, USB-C 20Gbps PCI Express 3.0 x4 Adapter, Data Only, Windows/macOS/Linux, TAA

I recently installed the StarTech.com 1-Port USB 3.2 Gen 2x2 (20Gbps) PCIe Card in my system, and I’m very impressed with its performance. The installation was remarkably straightforward—essentially a drop-in process. I simply inserted the card into an available PCIe slot, and it was recognized immediately by my system without any issues.The transfer speeds are excellent, delivering the high-performance 20Gbps speeds promised. It's been a significant upgrade from my previous USB ports, especially when dealing with large file transfers and high-bandwidth peripherals.Overall, this PCIe card is a fantastic addition for anyone looking to boost their system's USB performance. The easy installation and impressive speed make it a great choice for both casual users and those needing top-tier performance. Highly recommended!

I built my computer and came with the micro USB ports, but not this fast.

I already have a USB C 3.2 Gen 2x2 20Gbps port on my motherboard (Aorus X570S Master), but I found out that the controller runs on a PCIe 3.0 x2 lane, which is not ideal. So I purchased this card thinking I will have two 20GBps port in total, and this being a PCIe 3.0 x4 controller, I'll get the full bandwidth.Installing the card was easy, it is tiny, and worked almost straightaway. I forgot that if I use the last PCIe slot, one of the M.2 slot will be disabled. So I had to move the M.2 SSD from the slot that shares the PCIe lane with the x4 slot to another M.2 slot. Restarted the PC, windows automatically installed the driver needed.Just as I thought, the card works faster than the built-in one, since it got the full x4 lane. It might work even better if I install it in the 2nd 16X slot, but I have a RAID controller installed there so couldn't do that.There was a nice 400MB/s bump, and the Acer Predator 4TB SSD installed in a Yottamaster 20GBps NVMe enclosure reached 2000MB/s on both read/write, which is sweet! Now I have 4 SSDs which can do my backups very very fast.A great card, works very well, and a no hassle installation. Just give it a slot where it can use PCIe 3.0 x4 lanes, and you are good to go. Also, a good 20GBps cable is recommended.

This board works very well. I connected a couple of CF-Express B USB 3.2 Gen 2x2 readers (Transcend and Lexar) and I got the expected speeds without any problem. (More than 10Gbs, so certainly unobtainable with plain Gen 2 that is capped at 10 Gbs). I addition it worked with any other device I tried 3.2 Gen 2 and 3.2 Gen 1 . This is contrast with the 3.2 Gen 2 ports on my motherboard (ASUS ROG Crosshair VIII) that often have trouble working with 3.2 Gen 1 devices and are in general very picky. Very good experience for me! (Caveat: you should use the right cable. Not every C cable is the same, you need a 20 GBs cable. I used a 3.3ft Cable Matters USB4 (look for B094STPLX3) and it worked great.

I used this to breathe some life into a very old X399 desktop system. I was looking to extend KVM + fast IO to the desktop over a mix of 3m and 4.5m cables, with the 4.5m being an OWC optical USB4 cable. For whatever reason the onboard 3.1 port on my X399 Designare only worked at USB 2 speeds when using the optical cable. Speeds were as expected with a 3m traditional copper cable but I couldn’t quite reach a convenient spot on the desk with 3m.I decided to gamble on this and it worked perfectly with the optical cable and Caldigit SOHO dock I’m using for desktop USB connectivity. Plug and play, zero intervention required on Windows 11.

Added this to an older 490Z motherboard primarily for VR. Don't need these speeds for VR but I wanted the higher power output to hopefully keep a Quest 3 charged during use. With WiFi off it does keep it fully charged. Wifi on it still falls but lasts a very, very long time.Testing with some external NVME drives it supports its full speed output too.

Thecard is not working at all, it shows an error on device manager, I installed in on PCI express x16 port, I reached out to Amazon whom transfered me to startech but neither was of any help, now am stuck with a defect card, very very bad experience.

Bough device that had usb3.2 support but my computer only supported 3.1. This caused a problem with the PC bootup hanging sometimes. After adding the card, the problem went away.
