The 4-Port USB 3.1 Gen 1 Type-A PCIe Adapter Card from StarTech lets you add four dedicated 5 Gb/s USB 3.1 Gen 1 ports to your PCIe x4-enabled PC. This independent port architecture improves USB 3.1 Gen 1 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 3.1 Gen 1 cards share maximum bandwidth between all ports. By employing four host controller chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5 Gb/s to each USB port reduces performance bottlenecks and effectively quadruples your total available bandwidth to 20 Gb/s.
The controller card is compliant with USB 3.1 Gen 1 standards while offering backward compatibility with existing USB 2.0 / 1.1 devices. For added versatility, the USB 3.1 Gen 1 PCIe card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form factor computers.
UASP Support
Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.1 Gen 1 controller performs up to 70% faster than conventional USB 3.1 Gen 1 when paired with an External Drive Enclosures (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multiple commands to be processed simultaneously, significantly increasing transfer speeds for less wait time on data transfers.
