StarTech.com 2 Port PCI Express (PCIe) SuperSpeed USB 3.0 Card Adapter with UASP - LP4 Power - Dual Port USB 3 PCIe Controller
Add 2 SuperSpeed USB 3.0 ports to your PCI Express-enabled PC
The PEXUSB3S25 2-Port PCI Express USB 3.0 Card lets you add two USB 3.0 ports to your PCI Express-enabled computer system, with an optional LP4 power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0).
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 is not supported by all operating systems). 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 PCIe USB 3.0 adapter is compliant with USB 3.0 standards for data transfer speeds up to 5 Gbps, while still offering backward compatibility with existing USB 2.0 / 1.1 devices. 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.
Backed by a StarTech 2-year warranty and free lifetime technical support.
Improved Performance with UASP
UASP is supported in Windows 8, 8.1, Server 2012 and Linux kernel 2.6.37 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 add-on USB 3.0 cards, a UASP-enabled StarTech enclosure, and a SATA III solid state drive.
The StarTech Advantage
- Increase efficiency of your USB 3.0 devices with up to 5 Gbps of bandwidth
- Fits into full or low-profile/small form factor (SFF) systems, with a dual profile design
- Power high-powered USB devices as necessary, with the optional LP4 power connector
