StarTech 4-Port SuperSpeed USB 3.0 PCIe Card with SATA Power Connector & UASP

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 multiple commands to be processed simultaneously, significantly increasing transfer speeds with less wait time on data transfers. UASP is supported in Windows 8, Server 2012, and Linux kernel 2.6.3 or later.

Note:

_UASP require a compatible operating system._
