Add four USB 3.0 ports with four independent channels, LP/SATA power, and charging support to your PC through a PCI Express slot. The PEXUSB3S44V 4-Port PCI Express USB 3.0 Card lets you add four, dedicated 5 Gbps USB 3.0 ports to your PCIe x4-enabled PC. This independent port architecture improves USB 3.0 performance by transferring data on four individual channels to your computer, giving you faster file transfers.

When multiple devices are connected, traditional single bus USB 3.0 cards share your maximum bandwidth between all ports. By employing four host controller chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5 Gbps to each USB port reduces performance bottlenecks, and effectively quadruples your total available to bandwidth to 20 Gbps.

Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating sy

Rated 5 out of 5 by from Great card but StarTech needs to update driversI have purchased 2 of these now. They work awesome BUT after a system upgrade to Ryzen 7 CPU and a ASRock mobo that has PCIE 3.0 and 2.0 ports the card will only function on the 3.0 slot. my last PC 2.0 slot was not an issue. The drivers have not been updated since 2012 and Windows default driver is no good... it sees the card but says it cant start... HELP!

Rated 5 out of 5 by from To big for teh backplate!Great card in terfms of specs, however, I've found that having the USB ports verticle rather than horizontal makes it impossible to actually plus a USB device in. The back plate of my PC is too narrow. Now I'm guessing the gap is industry standard so I have no idea how Startech managed to get this product out there. In order to make this work I'm going to need to physically file the back port to make the gap wider.

Rated 5 out of 5 by from Great card, wrong port orientationI bought this to allow additional peripherals. While the card is the best I found in terms of quality and speed, the USB port placement is terrible and it is impossible to plug anything into them unless I cut my case. An horizontal place would have been way more appropriate.
