The 4-Port SuperSpeed USB 3.0 PCIe Card with SATA Power Connector & UASP from StarTech adds 4 external USB 3.0 ports to any PCIe-enabled computer system with support for data rates up to 5 Gb/s. The card uses a "stacked" port layout that places the ports one on top of the other, enabling all four USB 3.0 ports to be external facing, while still allowing the card to fit into a small form factor/low-profile computer system using the included low-profile bracket.Additionally, with a built-in SATA power connector, each USB port can provide up to 900mA of power to devices that draw power from a host bus connection (500mA for USB 2.0) by connecting to your computer's power supply. 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. Using a more efficient protocol than the traditional USB BOT (Bulk-Only Transport), UASP technology optimizes transfers by allowing multi
