Review: Works, thogh read more - I just bought this a weak ago, and it has lived up to its ads on what it does. It has two independent usb 3.0 controllers, and both are connected to asmidia pci bridge(hint: it does get close to maximum bandwidth on both extenral ports.) This is an upgrade for me from an cheap 1x pcie febsmart 2 port black model I bought in 2019. That model is now unused, and it also was great. I am giving this product 5 stars, only downside is more then 3 times the price that pcie x1 low profile 2 port card was. So far febsmart products have yet to fail me, and this card due to dual controllers can handle two vga adapters at once. There is another model that has 4 controllers and 4 external ports and 2 usb 3.0 heaaders, but I am warry of that interference with my case due to several reviews saying it blocks the input of usb 3.0 cables due to zero clearence and whatnot. This product the 2 controller does not have that issue, and I installed the low profile bracket and as advertised it does not require power. In the future my plan is to buy a dock and connect to this. When I get it, I will edit this review and report of any problems. EDIT: It works! Wavlink dock usb 3.0 docking station. Using one of the 2 indipendentant controllers, this allows 4 montiors on my desktop with two coming from pc and two from dock.
Review: Works with two 5 bay USB 3.0 desktop attached storage devices. - I have two 5 bay USB storage devices attached to my computer. Each one has 5 12 tb drives and the other has 5 10 tb drives. The USB off of my mother board would only see 5 of the drives, and even then it would constantly lose connection. I then bought a cheaper USB card (around $20) and it also had similar problems. I read somewhere about this product and decided to try once more before giving up. This card worked perfectly. My Plex server has been running just fine on the storage devices for the past two weeks. It shows that sometimes it is worth paying more for something that just works. Very happy with the product. I am buying another one for my gaming PC with a Valve Index.
