general information

Great Versatility

The Mini PCIe USB 3.0 adapter card features two SuperSpeed USB 3.0 ports which deliver a blistering-fast data transfer speed of up to 5GBps while remaining backwards compatible with USB 2.0 and USB 1.0/1.1 specifications. It gives you an easy way to connect to your USB-enabled peripheral devices for quick backup or archiving.

Moreover, the each USB 3.0 port provides up to 900mA of power to quickly juice up your devices.

Improved Performance with UASP

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.

general information

At the same peak in testing, UASP also showed up to an 80% reduction in required processor resources.

general information

Note:* 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.

general information

Using the Mini PCI Express (Mini Card) form factor and offering compliance with PCI Express Gen 2, this adapter card is designed for use in the latest small form factor computer systems, such as Mini-ITX or custom embedded solutions where a standard PCIe card would not fit.
