Description: StarTech.com 4 Port PCI Express PCIe USB 3.0 Card w/ UASP - SATA Power - USB adapter - PCIe - USB 3.0 x 4 - for P/N: USB3S2ESATA3

Mfr Part #: PEXUSB3S4V

MSRP: $58.99

Add 4 external USB 3.0 ports to a low profile or standard computer, through PCI Express. 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.
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 (Note: UASP requires a compatible operating system). 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 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.
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.
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.
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, StarTech.com add-on USB 3.0 cards, a UASP-enabled StarTech.com enclosure, and a SATA III solid state drive.
Key Points
  • Dual profile (full-height and half-height) design fits into full or low profile/small form factor (SFF) systems
  • USB 3.0 PCI-E card has 4 external USB 3.0 ports using a space-saving stacked layout
  • Uses a SATA power connector for compatibility with newer systems that have limited or no LP4 power supply connections, to ensure maximum power for USB devices
