GRAUGEAR 3.5 Inch Front Panel USB C Hub, SD/microSD Internal Card Reader, 20Gbps USB 3.2 Gen 2x2, USB3.2 Type-E Key-A 20-Pin Header & USB3.0 Header & 15-Pin SATA Power Connector Required [G-MP01CR]

I wanted some USB-C on my computer case. Being that this case is from the early 2010s, it lacked these USB-C ports. Not only that, the included ports attached to the case were connected with unshielded wire. My wireless trackball was having trouble sustaining a connection to my computer due to this. This Graugear expansion is a must-have. It’s convenient and really renews my case’s functionality. I appreciate the steel construction and that this thing is built to last. Slide it in, screw it tight, plug everything in, and you’re good to go. 11/10 would recommend.

This unit is heads and tails above all the other front panel USB hub & card readers I've owned over the years.First, it's far more solidly built with the front bezel being solid metal so no chance of breaking those awful plastic tabs that most other units come with, being a part of the case itself which is also very sturdy and well-made.Second, perhaps earlier versions of this required you to insert the MicroSD card upside down, but I must have a newer version where they're inserted facing up.Also and more importantly, the faster of the two USB-C ports on the one I got was USB 3.2 Gen 2x2 so it goes up to 20Gbs, not 10Gbs as in the product page description and datasheet. This of course depends on your motherboard's capabilities and what you insert into it.Finally, it's fast. Not quite as fast as my X570S motherboard built-in ports, but just a hair slower. For example using CrystalDiskMark my Samsung 256GB USB-C flash drive tested at 433/118Mbs read/write on the MB's rear USB-C 3.2 Gen 2x2 port, and 399/118 on the Graugear's 5Gbs USB-C 3.2 Gen 2 port and 403/119 on its 20Gbs USB-C 3.2 Gen 2x2 port. That's close enough for me.Installation took longer and was more difficult than I expected, but that was entirely because of the way that my PC is set up with cables, connections and such. But the device itself is very simple and easy to install if you know your way inside a PC.I can't attest to long-term regular use as I only got it a few weeks ago and haven't been using it much, but on build, performance and even looks, it's a winner. A bit more expensive than what I've usually paid for such devices in the past but justified by its much higher quality.

I installed in a computer I built 9 months ago. Followed instructions and it worked great. Once. After that, the computer would not boot. No BIOS screen, no POST beep, nothing. Disconnected and the computer booted fine. Reconnected and had the same problem. Returning for refund

The screw hole placement seems to match that of an internal drive holder, not something that will protrude through the front of a computer case. This meant I was only able to insert one screw per side. I also had to replace the cable (which includes the front USB-C port) for the 20 Gbps port with one that ended in a 90-degree Key-A Type-E plug because for some reason, most 20 Gbps PCIe internal connection adapter cards (stupidly) have the socket facing to the side, interfering with other cards and the case and pretty much everything. Otherwise, this device seems to work well. I've attached the results of benchmarks of a Crucial X10 Pro Drive on the 20 Gbps port (which is really just a direct connection to the PCIe adapter) and the 5 Gbps USB-C port which is controlled by the included USB hub that also supports the two USB-A ports and the SD and Micro SD Slots. There is also a benchmark of a Sandisk Extreme Pro U3 microSD XC card. I docked one star for not having enough screw holes in the correct locations.

Installed simply enough. I've tested it on Linux (and Windows) and it is working well. It is really nice having all of the USB connections near each other at the front of my case. As it is a 3.5" form factor I used a 5.25" tray adapter.This is important -- it REQUIRES a SATA power connection to power the USB-A, microSD, and SD card slots. This is a physically small device with the SATA power connector near the front so its power connector will likely be farther away from your P/S and from the position of the SATA power connectors for your other devices. I used a SATA power splitter (like https://www.amazon.com/dp/B0BZ8RYD59) and used a couple of them to provide plenty of cable length to reach the front of this device and still reach my other SATA devices.

Tight fit in case. The power connector could be further back to accomodate shorter cables. Testing showed all ports worked to spec. Cables were plenty long for my large case. I connected the Type B to motherboard header and the Type C to a PCI 4X header card.

This product added much needed front USB 3.0 connectivity to the front panel that I was lacking, also included two(2) USB-C ports, and SD-Card reader for SD-Card and Micro-SD. However, card portion of the device DOA. I returned the device for an exchange. The card reader portion of the device work three or four times then never worked again. While it was working Windows 10 & 11 could see the card reader in the device manager. Then for some reason the card reader device disappeared from device manager never to be found or seen again. I tried hooking the device to two other motherboards. Still no card read was found. I do not use the card reader very oten, so I just use a separate multimedia card reader adapter that I plug into this device instead.
