ECUSB3S254F, Startech 2 Port Express Card USB 3.0 Card

ECUSB3S254F ExpressCard 54 to USB 3.0 Adapter

The ECUSB3S254F 2-Port Flush Mount USB 3.0 ExpressCard Adapter lets you add two USB 3.0 ports to your ExpressCard-enabled laptop.

The USB 3.0 card uses a unique 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 on the move, without having to worry about impact damage to either the card or the ExpressCard slot.

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 SuperSpeed USB 3.0 Card supports data transfer rates of up to 5Gbps, and is backward compatible with USB 2.0 (at up to 480Mbps), or USB 1.1/1.0 at up to 1.5/1.2 Mbps respectively - the perfect laptop accessory for users to connect USB devices, both new and old.

Improved Performance with UASP

UASP is supported in Windows® 8 and Server 2012. 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.
