StarTech.com 2 Port ExpressCard SuperSpeed USB 3.0 Card Adapter with UASP Support

The StarTech.com 2 Port ExpressCard SuperSpeed USB 3.0 Card Adapter is a compact, high‑performance expansion solution designed for laptops and notebooks that feature an ExpressCard/34 slot but lack modern USB 3.x connectivity. By inserting this adapter into the ExpressCard bay, users gain two full‑size USB 3.0 Type‑A ports, each capable of delivering up to 5 Gb/s (SuperSpeed). The inclusion of UASP (USB Attached SCSI Protocol) support further enhances data transfer efficiency, especially when working with external hard drives or SSDs that can leverage the protocol for faster read/write operations.

Key Technical Specifications

• Interface: ExpressCard/34 (34 mm width)
• USB Ports: 2 × USB 3.0 Type‑A female connectors
• Data Transfer Rate: Up to 5 Gb/s per port
• Protocol Support: UASP (USB Attached SCSI Protocol)
• Chipset: NEC uPD720200, a proven controller for high‑speed USB 3.0 applications
• Power Delivery: Supports up to 900 mA per port (standard USB 3.0 power limits)
• Dimensions: 34 mm width, designed to fit standard ExpressCard slots without modification
• Operating Temperature: −20 °C to +50 °C
• Material: Durable ABS plastic housing with reinforced metal contacts for reliable electrical connection

Design and Build Quality

The adapter features a sleek, black ABS chassis that matches most laptop aesthetics. The front panel is flush‑mounted to the ExpressCard slot, ensuring no protrusion that could interfere with docking stations or other peripherals. Each USB 3.0 port is equipped with a reinforced metal shield around the connector to protect against accidental damage and to maintain signal integrity during high‑speed data transfer.

Performance Highlights

Thanks to the NEC uPD720200 controller, the adapter delivers full USB 3.0 bandwidth, allowing users to stream high‑definition video, transfer large media libraries, or run external SSDs with minimal latency. The UASP feature is particularly beneficial for storage devices that support the protocol; it reduces CPU overhead and improves throughput by enabling command queuing and parallel data streams.

Compatibility

The adapter is universally compatible with any laptop or notebook that includes an ExpressCard/34 slot, regardless of operating system. It works seamlessly with Windows 10/11, macOS (via third‑party drivers if necessary), and Linux distributions that support USB 3.0 and UASP. No additional software installation is required on most platforms; the device presents itself as a standard USB hub.

Installation Guide

1. Power off your laptop and disconnect all cables.
2. Locate the ExpressCard/34 slot, typically found on the side of the machine.
3. Insert the adapter into the slot until it clicks into place. The connector should sit flush against the chassis.
4. Power on your laptop; the operating system will automatically detect two new USB 3.0 ports.
5. Connect your peripherals (USB flash drives, external hard drives, SSDs, etc.) to the newly available ports.

Use Cases and Applications

• Data Backup: Connect an external HDD or SSD for rapid backup of large datasets.
• Media Production: Transfer high‑resolution video files between laptops and storage devices without bottlenecks.
• Gaming: Plug in USB 3.0 gaming peripherals such as controllers, headsets, or external GPUs (via compatible adapters).
• Business Mobility: Expand connectivity on thin clients or ultraportable laptops that lack modern ports.

Why Choose This Adapter?

The combination of a robust ExpressCard/34 form factor, dual USB 3.0 ports, and UASP support makes this adapter an ideal upgrade for legacy laptops that still rely on older expansion slots. It offers a plug‑and‑play solution without the need for external power supplies or complex driver installations. The high data throughput ensures that even demanding tasks—such as 4K video editing or large database transfers—are handled efficiently.

Conclusion

The StarTech.com 2 Port ExpressCard SuperSpeed USB 3.0 Card Adapter with UASP Support delivers a powerful, reliable expansion path for laptops that need modern USB connectivity but lack built‑in ports. Its compact design, high data rates, and support for advanced protocols make it a versatile tool for professionals, creatives, and everyday users alike.
