Used this to expand the number of drives in a smallish Ubuntu home server. Still testing, but seems flawless so far and transparent to the user - just more drives available. All I did was power down, plug it in the PCIe 3.0 slot, attach a couple drives, and power up. Drives were recognized immediately and accessible like all the others. They claim max throughput of 277MB/s but so far both drives tested at 500 MB/s+ the same as when plugged into the mobo ports. I assume the limited speed might occur if multiple drives were accessed at once. Since it's a server and I'm using this to add SSDs, i doubt I will ever notice any slow downs. Bonus: the 6 provided SATA cables have locking connectors and are of a reasonable length.

Maybe a Necessity if You Have a USB-C on Front Panel Header because no USB 3.2 GEN1 connector on motherboard. The PCI-E 1X to USB 3.2 GEN1 5Gbps 20pin Front Panel Header allows you to connect the USB-C front panel header to your PCI-E 1X slot

Inexpensive. Gen4 NVMe or Gen3 if you need higher capacity at a lower price. Leave the top cover off and use NVMe with built-in heat-sinks if you like (as I did). Up to 12GB/s Write and almost 17GB/s Read speed with just 3 NVMe Gen4 (for now), 4th drive to be added soon and performance will therefore improve. And YES, that's Gigabyte per Second!!! While AM4 (AM5?) and other platforms wait for Gen5 NVMe... even THAT won't be this fast, expansive or especially as inexpensive as THIS solution. 4TB of this performance level isn't even $900. What those platforms are waiting for in 2 more years from now, I'm already enjoying over a year ago.. and will continue to for at least another 5+.

Windows 10 x64 recognized the board immediately and no driver installation was required. Unlike another reviewer's experience, there were no issues inserting the USB plugs. While the fit is snug, if there's a problem, it's with your case.

Even on an older motherboard it was still detected.
