1-Port USB 20Gbps PCIe Card, Windows/macOS/Linux (PEXUSB321C) | USB-C 20Gbps PCI Express 3.0 x 4 Adapter, Data Only, 2x2

Was sceptical as to the speed but it does as it says on the box

2000 MB/s no problem with T9 ssd .. Windows file manager obviously a bit slower but ive still seen 1.7 from that ..

It works

The QNAP 800 series USB-C enclosures do not work with many USB-C 3.2 controller cards and the OEM cards are scarce, so I thought I would give this card a try. The card is picked up by Linux immediately and the drives in the enclosure are all detected (certain other cards have random detection failures for some, not all, end devices). The QNAP management software likes this card, with no warnings on link speed or compatibility. Accessing individual drives sequentially, the maximum speed of the drives is reached. Testing access to all drives simultaneously achieved the 10 Gbps of the QNAP link. Very happy with this card and it has been running smoothly for 2 months now.

Got this in order to realise the full speeds on a Crucial X10 pro external drive that I got however so far am only able to get half the transfer speeds on the crucial drive. The drive is benchmarking at full speed on crystalmarkdisk so I have a bit of troubleshooting to do. On the plus side the card was easy to install and windows 10 recognized it straightaway so it was really just plug and play and away you go. If I can get it to utilize the crucial drives full potential I will upgrade rating to a 5. And if I don't it's always nice to have an extra usb c port on the back of my pc

had issues plugging in my meta quest 3 headset to my PC as there wasn't enough juice in the usbc. This still doesn't fully fix it but my headset lasts hours and hours when I have plugged in to this card

Got this to work with my Pioneer FLX-10 controller as PC don't have these new style usb sockets. It works perfectly fine with it.

Took a chance as Amazon Warehouse deals have been good. Sadly the card was not protected by antistatic bag, Does not work as not recognised by computer.

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.

Using this in my motherboard's secondary PCIe 4.0 x16 slot (effectively x4). Bought this card since it was one of the only options to get a USB 3 Type C port at least 10Gbps to provide 3Amps of power without any additional power connections. Connected my Meta Quest 2 VR headset using the UGREEN 16ft USB-C cable for VR. Works perfectly, running PC VR games at max refresh rate 120Hz, & battery stays at 100%.

I'm no expert in this area, i wanted an extra usb c output on my computer, as it only had one, and it was coping a hiding, and it seems to be doing the job OK

Qualità eccezionale, non c'è altro da dire. Usata per giocare in PCVR tenendo carico il Quest3, associato ad un ottimo cavo Type-c.

Product is excellent, but the delivery guy did not ring the bel. He threw it over the high fence of my house on a wet spot, knowing that I mentioned "strictly hand delivery" on Amazon App.
