PCI-E PCI Express 4X to USB 3.1 Gen 2 (10 Gbps) 2-Port Type C Expansion Card Asmedia Chipset for Windows 7/8/8.1/10/Linux Kernel (2XType C)

OS: Windows 10 EducationInstalled 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? :PI 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.

I have a five year old machine that works great. However the hub ports never worked quite right when converting USB-c through the larger USB connections. Highly recommend for the value ... simple and effective.

Unlike the utterly miserable dodocool alternative ( dodocool PCI-Express Card with Dual Type-C Ports 15-Pin Connector SuperSpeed Gen II (10 Gbps) for Windows 7 / 8 / 8.1 / 10 Linux Kernal , this one actually works! One major reason for the difference is that this Totovin product came with a Windows 7 driver disk, which is absolutely essential for that operating system.The "dodocool" product not only completely failed to work (and caused terrible crashes under Windows 7), but the manufacturer refused to help.My single criticism is that the user manual that comes with it speaks of hooking up a SATA power connector, which does not exist on this card (and which does come with the dodocool). That might have been useful for unpowered USB 3.1 devices...

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 = 5GbpsUSB 3.0 drive enclosure = 5 GbpsMechanical Drive = ~ 100 MB/secondSSD SATA 3 = ~ 550 MB/secondNVME in USB 3.1 Gen 2 Enclosure - 10Gbpsand 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 differentFor example, a graphics card might use 16 PCI LanesEach SATA port is 1 LaneEach SSD Drive is 2 LanesEach USB 3.0 port is 1 LaneNVME drives use 4 lanesIt does not take long before your run out of lanes.I have in my system1 GPU = 16 Lanes8 USB 3.0 = 82 NVME Drives = 82 USB 3.1 = 4 (this card)3 SATA HDD Drives = 3If 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.

Seems to work as intended so far. My BIOS only detects the 4x lane at 2x however.

Easy to install. does not work. return for refund. bought 2 Mediasonic USB 3.1 4 Bay Enclosure for my 8 hard drives. For the record, these USB enclosures work but slower than my $420 LSI SAS 9201-16I pcie card.Question: what to do with 22 HDD?My case holds 24 drives: 8 - 4 tb, 10 - 5 tb, 4 - 16tb , plus 2 SSD 1tb and 2 m.2 1tb .my ASUS WS Z390 PRO motherboard has 6 SATA ports: 4 for the 2 m.2 and 2 for the SSD. 16 HDD connected by LSI SAS 9201-16I.8 4TB HDD connected by USB. I know 16 drives are old but none have bad sectors or SMART warning.Is there a better solution than what I did?

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.

Excellent to deal with.
