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!

USB 3.2 Gen 2x2 (20 Gbps) | PCI-Express 3.0 | PCIe x4 Slot | USB Type-C
Add a 20 Gbps USB Type-C Port to Your Desktop Computer
The controller card enables you to connect USB-C Gen 2x2 (20 Gbps) devices to your desktop computer. The USB-C port is ideal for connecting USB devices such as external hard drives & solid state drives or charging & syncing mobile devices.
The USB-C port provides up to 15W (5V/3A) of power and is backward compatible with USB 3.2 Gen 2 (10 Gbps) and USB 3.2 Gen 1 (5 Gbps) devices.
SuperSpeed USB 3.2 Gen 2x2 (20 Gbps) Performance
The USB 3.2 Gen 2x2 card features an ASMedia ASM3242 host controller that utilizes x4 lanes of the PCIe 3.0 bus, making the card capable of speeds up to 20Gbps and enabling fast access to high-performance devices like NVMe drives and SSDs.
The controller card supports Multiple INs to reduce bandwidth loss when multiple devices are connected through a USB Hub. (Note: The USB hub must also support this feature). The card also supports UASP for improved performance with storage devices.
Wide Installation Compatibility
This add-on card includes both full-profile and low-profile installation brackets ensuring you can install it into either a full or low-profile PCIe 3.0 x4 slot (backward compatible w/PCIe 2.0).
For wide platform support the card is compatible with Windows, Linux and macOS.
For hassle-free installation the drivers install automatically on computers running Windows 8 or higher. Works w/USB 3.1/3.0/2.0 devices

ASMedia ASM3242 works really well!
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.
