Power

Product Description

Add 4 USB (Universal Serial Bus) 3.0 ports to your desktop computer through a PCI Express expansion slot. The PEXUSB3S4 4-Port PCI Express Super Speed USB (Universal Serial Bus) 3.0 Card (with SATA Power) adds 3 external USB (Universal Serial Bus) 3.0 ports & an internal USB (Universal Serial Bus) 3.0 port to any PCI Express-enabled computer system. With Super Speed USB (Universal Serial Bus) 3.0, you can reach data transfer speeds up to 5 Gbps, while still being backward compatible with existing USB (Universal Serial Bus) 2.0 devices at 480 Mbps. Enhanced with UASP support (USB Attached SCSI Protocol), this USB (Universal Serial Bus) 3.0 controller performs up to 70% faster than conventional USB (Universal Serial Bus) 3.0 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating system). Using a more efficient protocol than the traditional USB (Universal Serial Bus) 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 (Universal Serial Bus) port can provide up to 900m A of power to USB (Universal Serial Bus) 3.0 devices (500m A for USB (Universal Serial Bus) 2.0) by connecting to your computer power supply. For added versatility, the controller card is equipped with a standard profile bracket &

Includes:: a low-profile/half-height bracket for installation in small form-factor computers. UASP is supported in Windows 8, Server 2012 & 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 (Universal Serial Bus) 3.0 at peak performance. At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources. Test results were obtained using an Intel Ivy Bridge system, Star Tech.com add-on USB (Universal Serial Bus) 3.0 cards, a UASP-enabled Star Tech.com enclosure, & a SATA III solid state drive.
