Sonnet 2 Port SuperSpeed USB 3.0 PCI Express Card with UASP - SATA Power - PEXUSB3S22
The PEXUSB3S22 2-Port PCI Express SuperSpeed USB 3.0 Card (with SATA Power) lets you add 2 USB 3.0 ports to any PCI Express-enabled computer system. With SuperSpeed USB 3.0, you can reach data transfer speeds up to 5 Gbps, while still being backward compatible with existing USB 2.0 devices at 480Mbps.
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 system). UASP is supported in Windows 8, Server 2012 and Linux kernel 2.6.3 or later. In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance. 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.
With a built-in SATA power connector, each USB port can deliver up to 900mA of power to USB 3.0 devices (500mA for USB 2.0), by connecting to your computer power supply. For added versatility, the controller card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.
