StarTech.com - PEXUSB3S4V - Add 4 external USB 3.0 ports to a low profile or standard computer through PCI Express - Compatible with Lenovo ThinkCentre M93p / Dell OptiPlex 3010 - 4 Port PCI Express SuperSpeed USB 3.0 Card Adapter with UASP / 4 Port USB 3.0 Controller Card - USB 3 PCIe Card / PCIe USB 3.0 Card - SATA Powered USB 3.0 PCI Express Card / PCI Express USB 3.0 Expansion Card w/ UASP - Desktop PCIe USB 3 Expansion Card / Add USB 3.0 Ports to a Desktop - USB 3.0 UASP Card includes a Low Profile/half-height bracket - Manufacturer Limited 2 Year Warranty.
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 UASP supported enclosure (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. See our UASP test results below for further details.
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.
