Review: Works well with Esxi and Server 12 - The FS-4C-U8S-Pro is a newish (2019), Pcie Gen 3, low profile, well designed (big heatsink), four channel USB 3.0 host bus adapter. The low-profile design dictates the horizontal port placement, which some reviewers have found problematic in aligning with case slot openings. My experience, with a Lian-Li server case, is the port connector fit is snug but perfectly serviceable (try plugging in the cables before tightening the retaining screw). In addition to the 4 external ports, there are two 19 pin headers for attaching another 4 ports (though those will share bandwidth with the externals). There is also a SATA power header to provide more amperage to the ports, should you be connecting USB powered disks or other power-hungry devices. The controller chip used is the Renesas uPD720202, one per channel. My environment is an Intel 8700K CPU running VMware Esxi 6.7 U3 Free as a host OS, with a Windows Server 2012R2 VM and a couple of low use Windows 10 VMs. Performance is what I expected for rotating hdds: 200/208 Mb/s single disk, 240/258 Mb/s Raid 5 measured with ATTO, and no degradation on simultaneous usage of all 4 ports. The heatsink does a good job of keeping the chip operating temperature at 95° F in a well-ventilated case. I perform two types of daily backup to four USB 3.0 raid enclosures attached to a Server 12 Esxi VM (about 3 - 5 Tb per day). The motherboard USB controllers were unreliable in heavy usage, regularly dropping connections during backups. I tested 3 quad channel (Pcie x4) adapters in my quest to obtain reliable USB 3.0 connections for my server. This was the only card that I could get to work. It works reasonably well with individual USB devices assigned through VM settings, occasionally (randomly) dropping a device, but it works great with PCI device passthrough configured. To get passthrough configured, I had to set the ‘VMkernel.Boot.disableACSCheck’ switch to True. I have been beating the heck out of this thing 24 hours per day for a week now, and no dropped devices or failed backups. UPDATE: 1 1/2 years later and everything is still good. 100% port reliability. No issues.
Review: Using this to power up my docking station - I bought this a over a year ago and still works. Like its 2 channel counterpart but tricky to install, my case is compatible with the device, albet barely. I am currently using 2 channels plus a third for internal flash drive from one of the usb 3.0 headers. I have no problem with the usb pcie x4 4 channel. My docking station uses 1 of the external usb 3.0 ports and has no bandwith starvation like it did when connected to central usb 3.0 ports. I have a lot of usb devices connected to my desktop, and this is the best solution I needed. I also connect usb hubs and what not, and they all work. This is a great docking PCIe x4 in my pc, which is low profile and only 1 pcie x 16 slot. At the moment the 2 channel is not being sold, but this one is. That one was good as well, but I wanted 4 channels in one pcie x 16 slot, and they made it compatable with 1 slot as well. The only real downside of this its a lot more expensive, but its worth it. It also uses 20 MSI, or 5 for each usb pcie chipset.

### ⭐⭐⭐⭐ Works good
*by S***. on November 5, 2022*

Works really good, has a good chipset on it. Speed is as expected all ports work. Doesnt look bad and small enough to not block airflow to gpu. Major pro. Last one i had messed with the file structure saying i had 3 of everything i plugged in. I got this one because i wanted speed and did not want a stupid file path system. This works good. Cons: Ive had only 1 or 2 bugs where my computer had to re-reconize/it would disappear for a microsecond but that issue went away after a few days of use. Price
