ExpressCard 34mm USB 3.0 adapter

This adapter adds two USB 3.0 ports to a laptop or desktop that has a 34mm ExpressCard slot. It is aimed at users who need extra high-speed connections for external drives or peripherals on older hardware. The card fits the 34mm form factor and is not compatible with 25mm or 54mm slots. Apple laptops are not supported.

34mm ExpressCard slot required

The single deciding specification is the physical 34mm ExpressCard slot on the host machine. If the system only offers a 25mm or 54mm slot, the card will not fit and cannot function. Driver installation is mandatory on every supported Windows version before the ports become active.

Sustained transfer at 5Gbps

Under continuous load the adapter maintains the USB 3.0 SuperSpeed rate of 5Gbps, falling back to 480Mbps High-Speed and 12Mbps Full-Speed for legacy devices. The dual ports share the ExpressCard bandwidth, so simultaneous heavy transfers on both ports will divide the available throughput.

Questions about this item

What does the 5 Gbps transfer rate mean when I plug devices into the adapter?

The 5 Gbps figure is the Super-Speed ceiling of the USB 3.0 ports; real-world throughput will be lower and depends on the connected drive or peripheral.

Which ExpressCard slot width does this adapter fit?

It fits a 34 mm ExpressCard slot only; it will not work in 25 mm or 54 mm slots.

Does the card need any extra power or brackets to install?

No external power or mounting bracket is required; the card draws power from the slot and inserts directly.
