I installed this card in my second video slot (PCIe x8) since my system has no PCIe x 4 slots. Windows 10 ver 1709 build 16299.192. Windows installed the device and UASP drivers automatically at boot time. With the StarTech 3.1 UASP compliant external drive enclosure that I purchased at Amazon and a SATA 6gb/s SSD I already had on hand , I immediately noticed an impressive speed increase vs when the enclosure was plugged into my onboard USB 3.0 UASP compliant port. I then benchmarked the new setup with CrystalDiskMark 5 and was amazed by the results. Especially on write performance. Macrium Reflect 7 imaging of my system disk improved from 42 to 27 minutes Whoa Nellie! Check your system for an available PCIe x 4 or higher slot before you purchase as this card will not physically plug into a PCIe x1 slot. This card has an Asmedia ASM1142 chipset so x1 would be too slow anyway.

Plug and Play Simplicity

Not much to tell. Dropped it into an open PCI 3.0 4x slot instantly recognized by Win 10. Tested with Fast 10Gbps cables USB C - 3.1 Gen 2. Instantly received expected speeds. In my case rates were about 600MB/second which is limited my my SATA 3 drive, not the interface. Previously with my build in USB 3.0 ports I was only receiving about 350MB/second. Make sure you get properly rated cables, not all cables are the same. Make sure the mfg states USB 3.1 GEN 2 AND 10Gbps with Embedded Chip in the cable. Don't forget you are limited the slowest link in the chain. Cable without Chip = 5Gbps USB 3.0 drive enclosure = 5 Gbps Mechanical Drive = ~ 100 MB/second SSD SATA 3 = ~ 550 MB/second NVME in USB 3.1 Gen 2 Enclosure - 10Gbps and so on. Final thought. Not all CPU's and Motherboards are created equal. Read up on PCI Lanes and make sure you are not, for example, stealing lanes from your Graphics card when you add this card. * Again every CPU and Mother Board handles devices differently so your results and calculations may be different For example, a graphics card might use 16 PCI Lanes Each SATA port is 1 Lane Each SSD Drive is 2 Lanes Each USB 3.0 port is 1 Lane NVME drives use 4 lanes It does not take long before your run out of lanes. I have in my system 1 GPU = 16 Lanes 8 USB 3.0 = 8 2 NVME Drives = 8 2 USB 3.1 = 4 (this card) 3 SATA HDD Drives = 3 If I were running all devices at the same time then I am potentially using "at least" 39 PCI lanes. My PC only supports 40 lanes. WIth my Xeon 12 Core Processor, I am maxed out. If I add any more cards then it will impact something else. My example might not be 100 percent technically perfect for all users, but just know that you can max out your system even if you have "more slots" available. So I am maxed out at 40 lanes with a server based processor. Many home user CPUs only support 16 lanes total.

Great USB 3.0 extender with 1 issue

I had a problem with another 7 port PCI usb card. Only 2 out of 7 ports worked. This one however works perfectly. I tested each port out to make sure each one worked. The only issue is that one the card was installed there was an issue with screwing it in. The hole needs to be made bigger. It causes an issue with the usb ports not fully being visible or lined up so when I went to plug a usb in it wouldn't go in since the screw didn't align it right. Its a manufacturer defect. What I did was plugged in a usb on the first port and then screw it in. It was tight but I was able to get access to all the usb ports. The only other option would be to make the hole bigger where the screw goes in to secure the pci card.

Just what the Doctor ordered for large files

I put this little card in an HP 8300 desktop PC running Win 10 Pro to help out with backing up large directories of music and videos. I chose to pair it with Samsung T5 SSDs. I could not be happier with the result. I have seen transfer rates approaching 400mbps on large files. I regularly see 150-250mbps on smaller files in the 30-50mb range. No setup needed. I just opened the case, popped the card in, closed the case, booted up, plugged the T5s in, and started running it. Couldn't be easier. If you have large files, you need a good robust card like this. I am very happy.

Simple way to add 2x USB-C, 3.1 Gen 2, Ports to your desktop.

OS: Windows 10 Education Installed to a PCIe 2.0 x 16 slot on an ASRock B450m/ac AMD AM4 Promontory motherboard. The 3.0 slot has a GTX 1080 in it. It is a matx build, so things were a bit tight. It is probably a cm away from the GPU and only a few cm away from the PSU housing, and very close to headers on the mobo, but that was fine. It was such a small card that it fit without touching anything directly while also not blocking any fans directly. I doubt it will cause an airflow issue. My ONLY gripe is that the bracket didn't fit flush to the case, but it is neglible. While in Windows, I was surprised to find that device manager didn't acknowledge anything to address and Windows didn't tell me anything. I actually don't know what this pops up as in device manager. However, I plugged in a USB-C drive, a Nintendo Switch, and a Samsung Galaxy S8 and was very pleased. I haven't run benchmarks yet. The USB-C drive transferred files quickly, the Switch charged, and the Galaxy S8 was instantly recognized, charged, and allowed file transfers. Essentially plug and play. I didn't have to hunt down any drivers. It did include a CD and a bracket for a smaller case too. Who has CD drives these days? :P I bought an Amazon Warehouse used card. It cost about $16 after tax with Prime Shipping. It took a while to get here, due to the pandemic, but looks to be brand new. For that price, I am ecstatic. Hopefully this works flawlessly for a long time and I don't have any issues like some of the other reviewers.

Perhaps not 10Gbps but ...

Well, I can't see the 10Gbps but I'm not going to complain - it's pretty fast (SSD @ 385MB/sec, no problem hitting max transfer rates on WD Reds). Power: I have no available power to drive other USB PCIe cards, as many require such power - so this was a big selling point to me. The drives are externally powered and this little card does a great job, not having to support spinning the disks. *NIX does show this as a 10Gbit interface. It was, essentially plug and play. I had to do nothing to get this to work with Proxmox. Connected to a Mediasonic USB 3.1 cage. I haven't tried connecting to both USB ports on the card - that will probably come later. I expect my throughput to drop if each port is being used. Still, nice card - a lot cheaper than a quality 10Gig fiber card for iSCSI.

Super Plug-n-Play on Windows 10 Fall Creators Update

Kind of ironic that I built a PC with an optical drive, so I could've used the included CD to install drivers but I didn't need it. After the simple physical installation, I turned my computer on and by the time I entered my Windows password, the thing was already set up on Device Manager.

Great for a Linux NAS solution - faster than a normal LAN

I installed this on my Linux Mint server, an old Dell PowerEdge 1950 (Linux Mint 18.3, kernel 4.4.0 - please, no grief about running a desktop OS on a server - I have my reasons). It was recognized immediately with no special drivers required. I connected it to a MediaSonic ProRaid USB 3.1 (running in "Single" mode) with a pair of Western Digital "Red" 4TB drives. I formatted them with the "btrfs" file system in "raid1" mode. Locally I'm getting 200MB/s (megabytes) in write speed, and up to 1300MB/s read speed (disk speed, not cached). Over the past two weeks I've copied 4TB of data onto that external storage with no problems. Over my wired LAN, as my NAS, speeds top out at 96MB/s write and 113MB/s read - because of course my 1Gb/s (giga*bit*) LAN is slower than my 10Gb/s USB 3.1 connection. If you want to replicate my results, see comments for the script I used to test speeds.

Add USB3.1 Type A + Type C Gen2 Port to your old Mobo

The card simply does what it advertise, easy to install. It is one of those install and forget type cards, you install it once, windows automatically installed drivers. Connect port/USB hub and it works. I have had the card for a couple of month now with 0 issues. Please note that the card is PCIe x4. it can be installed in x4, x8 or x16 port but will only work as x4 card. You can expect full bandwidth if installed in PCIe 3.0 port, you will get slightly less performance if installed in PCIe2.0 port. (hardly noticeable unless the USB device connected is like a super fast SSD that can saturate the full bandwidth of the port)

Excellent card, and works great

I have an Evga x99 Classified motherboard with onboard USB 3.0, but it seems it has issues with my Valve Index VR headset, and would cause up to five second dropouts. This was frustrating. After just about giving up on the headset, I saw this card, and figured I would give it a shot (along with USB-C adapters), and voila, it fixed the problem. My Valve Index runs great with this card. I highly recommend this card for those needing high bandwidth applications without issues.
