This PCIe USB 3.2 Gen 2 controller card installs into an available PCI-Express x4 slot in your computer and enables you to upgrade your current system by adding four SuperSpeed USB-A (10Gbps) ports. The card features dual ASM3142 controllers with up to 20 Gbps of total bandwidth shared across all 4 ports. Add Four 10 Gbps USB Type-A Ports to Your Desktop Computer The controller card enables you to connect four USB-A Gen 2 (10 Gbps) devices to your desktop computer. The USB-A ports are ideal for connecting USB devices such as external hard drives and solid state drives or powering and syncing your mobile devices. The USB-A ports provides up to 4.5W (5V/0.9A) of power per USB port, and are backward compatible with USB 3.2 Gen 1 (5 Gbps), and USB 2.0 (480 Mbsp) devices. Note: USB 3.2 Gen 2 (10 Gbps) is also know as USB 3.1 Gen 2 (10 Gbps), and USB 3.2 Gen 1 (5 Gbps) is also know as USB 3.0 and USB 3.1 (5 Gbps). SuperSpeed USB 3.2 Gen 2 (10 Gbps) Performance The USB 3.2 Gen 2 card features dual ASMedia ASM3142 host controllers that utilizes x4 lanes of the PCIe 2.0 bus, making the card capable of speeds up to 10 Gbps on each port, and enabling fast access to high-performance devices like NVMe drives and SSDs. The controller cards support Multiple INs to reduce bandwidth loss when multiple devices are connected, even when 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 a full-profile installation bracket ensuring you can install it into full-profile PCIe 2.0 x4 slots.

Seems as if all the USB-3 PCI-E cards on the market these days are manufactured with significant faults or high level of fault tolerances. Recently, my cheaper more affordable ~2016/2017 Mailiya PCI-E USB PCI-E hub card failed, or is requiring manual firmware updates after each O/S boot. (Mailiya is a Japanese subsequent board version of the Innatek USB-3 PCI-E card, and recently testing the Innatek board proved it being faulty.)
Granted, this StarTech board costs a pretty penny, especially these days at ~$156, but finally something that just works. And as a bonus, the board is supported using Linux.
Well boxed within an easily opened cardboard container, wrapped once in anti-static bag, then bubble wrap bag, all easily opened. Upon first appearances, the board is slightly flimsy; however as long as it works, whom I to complain?
Using Void Linux, and posting some preliminary tests here. A note, testing should be consistent, versus my checks for only stability/reliability here. (My main tests or usage are with external hard drive mirroring operations, requiring days/nights of time for completing each task. And will likely not know the true performances for months.)
Upon some brief testing using rsync (rsync -axv --info=progress2), USB port speeds also appear much more stable versus the cheap/smaller hub type PCI-E USB cards. On Linux with "mount -o sync", a 2.7GB file ~29-30 MB/second, while under Windows 10, a 234MB file @ ~31-32 MB/second. Varying file sizes and number of files all affect USB transfer rates. These speeds were tested using an additional USB-3 powered hub connected to the StarTech PCI-E card, with Samsung 64MB 3.1 USB flash media.
If somebody asked if I would buy this product again, I would have to say, "Yes! YES! I definitely would!" ... mainly poking pun at ... just give me a simple USB PCI-E card that just works, rather than more broken garbage, wasting shipping resources.
