StarTech 2-Port ExpressCard 54mm USB 3.0 Card Adapter with UASP

The 2-Port ExpressCard 54mm USB 3.0 Card Adapter with UASP from StarTech allows you to add two USB 3.0 ports to your ExpressCard-enabled laptop. This SuperSpeed USB 3.0 card supports data transfer rates of up to 5 Gb/s. It is backwards compatible with USB 2.0 and USB 1.1/1.0 with data transfer rates up to 480 Mb/s and 12/1.5 Mb/s, respectively. This USB 3.0 card has a flush-mount design that allows it to sit flush in a standard 54mm laptop ExpressCard slot, creating a seamless add-on that can be left installed even while you are on the move, preventing damage to either the card or the ExpressCard slot.

Enhanced with UASP (USB attached SCSI protocol) support, this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure. 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.
