Backward compatible with USB 2.0, USB 1.1, Supports Low-speed 1.

USB 3.0 ports supports data transfer speed up to 5 Gbps.

VIA VL805 chipset for best performance and widest compatibility.

Transfer videos, photos, music and data files at blazing fast speeds. Test results were obtained using an Intel® Ivy Bridge system, add-on USB 3.0 cards, a UASP-enabled enclosure, and a SATA III solid state drive.The QuantumZERO USB 3.0 4-Port PCIE Card upgrades your desktop computer or server to USB 3.0 SuperSpeed ports, boasting data transfer rates of up to 5Gbps. In testing UASP performed with up to a 70% faster read / 40% faster write speed over traditional USB 3.0 at peak performance.Īt the same peak in testing, UASP also showed up to an 80% reduction in required processor resources. UASP is supported in Windows® 8 andServer 2012. Do those numbers give enough info to locate drivers My Computer iko22 Posts : 2,924 Windows 7 圆4, Vista 圆4, 8. It is installed in a HP a6400f with dual core e2200 CPU. The only markings on the card are DW-VL805-T4B and TX29. Plus, 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 power supply.īacked by a 2-year warranty and free lifetime technical support. 4 port usb3.0 card I think I need drivers for usb card, but I dont remember who I purchased it from. 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. See our UASP test results below for further details. 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. The PEXUSB3S4V PCI Express USB 3.0 Card (with SATA Power) adds 4 external USB 3.0 ports to any PCI Express-enabled computer system with support for data rates up to 5 Gbps, while remaining backward compatible with USB 2.0 / 1.x devices.Įnhanced 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).
