I was hesitant about which PCIe card to buy, given that there are so many with varying price ranges, features, reputations and most offputtingly, reviews! Originally I was looking at StarTech.com's 2x USB-C PCIe card for around £50. I had never heard about Inateck before, but with the addition of 3 x USB 3.0 (you can never have too many) and for a slightly cheaper price, I felt it was the right choice to make, and so I threw my dice... I'm so happy with the result. Fantastic power for a good price. Just stick it in and off you go. No driver updates necessary! Don't hesitate to buy this if you're umming and ahing; you'll be very pleased with your purchase

Bought this to replace a USB 3.0 PCI-E card which was slow and caused PC boot-up problems. No such issue with this one - driverless install, boot problems gone and transfer speed from external drives really fast. Slightly more expensive card than others, but well worth the extra outlay as it works properly / reliably.

Everything works to spec, and this is surprisingly good considering I am using this card on a legacy Mac Pro 2012 5,1 desktop. Only issue I have encountered is when selecting the Logitech BRIO into a USB 3.1 Type A port and selecting the camera in the Zoom web conferencing app, in HD mode. Zoom does not crash with HD mode turned off, and under identical circumstances in Windows 10, or MacBook Pro running Big Sur with HD ON. I can operate the camera in Low Resolution mode, or choose HD mode when plugging into one of the USBC ports on the card. Still trying to find out whether this is 30fps or 60fps. I raised tickets also with Zoom and Logitech over this issue, and no-one has a clue so far.

Have this on my PC for almost a year now. Transfer speeds are very high. Gigabytes of data moved in seconds!

After installing the card on a PCI express x 4 slot (PCI express Gen 3). The PC refused to boot. Removing the card and PC boots normally. Tried several x4 and x8 slots with same result. Also tried on a different PC, same result. Returning the card for a refund.

Easy to install and enjoy this 3.2 gen2 card. It's fast and will work on a Mac & PC. Quality product and worth buying.

This is working fine in terms of specified power output and data rate. Also, worked out of the box with Ubuntu Linux. However, when I use to drive a usb dac, there is significant electrical noise on the DAC sound when compared to plugging directly in to my motherboard usb ports. The noise is mostly from the PCI-E bus power as gets a lot worse when the graphics card is working hard.

I was looking for some additional USB 3 and USB C sockets for my PC, as I have a lot of external hard disks, controllers and other peripherals. I did not want the hassle of additional internal power connectors, and this was one of the few reasonably priced cards that gave what I was after. Packaging was small and basic but perfectly good enough. Installation was simply a matter of plugging in to a spare PCI slot - windows 10 sorted out the drivers automatically. It just worked. Plugged in devices functioned without any fuss. Not tested the bandwidth or throughput claims yet - but note the the top four sockets (I think) share the same controller and bandwidth (only an issue if you are using multiple data hungry devices at the exact same time). The bottom one should be full speed. Overall, very happy with this card.

The card works perfectly in Linux Mint 20.3 (kernel 5.13.0.40). Plug and play. Just Installed it and it is also compatible with AMD IOMMU. I was using a crappy VL805 USB3 PCIe to USB card. The problem with that card was that it was not compatible with AMD IOMMU and I had to disable that setting in BIOS resulting in lower performance. The second problem was that I was getting nowhere near USB 3 (5 gbps) speeds. Now, with Red Comet U21 I get full (10gbps) speeds (tested with an external SSD) and there is no problem with AMD IOMMU. Also, I've installed it on a PCIex 2.0 x4 and it still achieves full SATA3 speed (~ 600 MB/s)! If you have a external nvme (greater than 600 MB/s speed) then you need to connect the card on a PCIex 3.0 x4 slot to get speeds greater than 600 MB/s (SATA3). So, unless you need to connect an external nvme, no worries if your motherboard does not have a PCIec 3.0 slot. Make sure that you have a x4 slot. GREAT PRODUCT!!!! I have no usb-c devices to test, but it is a very nice addition for my motherboard which I intend to use for many years.

va igual de bien en un macbook pro 5.1 de 2010 que en un PC gaming de última generación.

I had been reluctant to add PCI-E Cards to my big I9 computer for fear of 'restricting' its pure grunt. But this new PCI-E Card has more than trebled our data transmission speeds and it was so easy to install. Great result and no problems with Driver Updates either . . . Totally recommended and a great price.

Perfect for a mac Pro 4,1 / 5,1

I use an older MacBook Pro (mid-2012), which has a total of two whole USB3 ports on the side. When at home, I use Thunderbolt to dock to an external PCIe expansion chassis, which I have populated with one of these cards. Inateck has thought about almost everything. Data throughput is amazing: the speed is just {chef's kiss}, and ease of installation is a breeze. It's even bus-powered, so you don't need to worry about about finding a free SATA power cable (if you're in a desktop machine) or try to rig up some Frankenstein-esque power adapter for the Thunderbolt box. The thing just works -- no drivers required -- PC, Mac, and Linux, and has been a lifesaver for me because I've got a metric tonne of USB devices that I need to have plugged in at once, and I don't want to bog down my notebook's internal USB bus with bunch of daisy-chained hubs. I've even gone so far as to get a second card for my gaming PC, and a second Thunderbolt expansion chassis, just so I can add another one of these to my laptop (yes, I have that many USB devices -- see included images). Also, because this card is a USB3.2 gen 2, it offers an upgrade over the built-in, vanilla USB 3.0 ports that my MacBook Pro clings to, which is also nice. If you're using a mid-2011 MacBook Pro, which only has USB 2.0, the upgrade is even more bombastic. The inclusion of two USB-C ports is also a great selling point, even if there are only two. They perform their duties with gusto and grace, and I cannot conjure any complaints at all about this product. All this for forty bucks, mind you, when similar items with far fewer ports can go for twice as much, at least. I definitely recommend this product to anyone that needs more USB ports, be it on your gaming rig, bidness computer, or notebook computer's Thunderbolt box. You cannot beat this for expandability and ease-of-use for the price.
