2 Port ExpressCard SuperSpeed USB 3.0 Card Adapter with UASP Support

Add two USB 3.0 ports to your laptop through an ExpressCard slot

Product ID: ECUSB3S2

2,5 stars (2 reviews) |
  • Fully compliant with USB 3.0 rev 1.0 specifications and Intel xHCI rev 0.96 specifications, with transfer rates up to 5Gbps
  • UASP support for more efficient data transfer
  • Backward compatible with USB 2.0 and 1.1/1.0 devices

The ECUSB3S2 ExpressCard USB 3.0 Adapter lets you add two USB 3.0 ports to your laptop through a 34mm 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 External Drive Enclosures (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.

Featuring a native NEC host controller chipset, the USB 3.0 ExpressCard 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.

Backed by a StarTech.com lifetime warranty and free lifetime technical support.

Improved Performance with UASP

UASP is supported in Windows® 8, Server 2012 and Linux kernel 2.6.3 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.

5VDC Power Supply Required

By: KC89 - 03/14/2014
The card requires a 5VDC external power supply which should be offered with the unit as an option. Most devices plugged into this unit require this.

works ok, but finicky functionally

By: alex - 02/27/2016
the main limitation is one of the expresscard port. it is very hard to plug\unplug one drive at a time due to the catch of the card being less strong than the catch of the usb ports. since expressport also has the press to popout feature I tend to pop the card out accidently while pushing in the usb cord. as noted by another this will not supply power to smaller drives without an external 5v power supply. a bit annoying that it doesn't have one, but since two of my usb3 drives are self powered not a deal killer for me
