AJA Video Systems has launched the Io Xpand, a Thunderbolt 5-enabled expansion chassis designed to integrate KONA and Corvid PCIe I/O cards into modern desktop and laptop workflows. The device provides a bridge for professionals requiring high-performance video connectivity on workstations that lack sufficient internal PCIe slots, according to official specifications released by AJA.
How the Io Xpand Bridges PCIe and Thunderbolt
The Io Xpand functions as an external enclosure that houses a single PCIe card, allowing users to utilize AJA’s KONA or Corvid series cards via a Thunderbolt 5 connection. By providing this external bridge, the unit enables high-bandwidth data transfer required for uncompressed video I/O, 12G-SDI workflows, and multi-channel audio processing. According to AJA, the chassis maintains the technical performance of a direct PCIe slot connection while offering the mobility and modularity of a Thunderbolt-based peripheral.
Why Thunderbolt 5 Matters for Video Professionals
The transition to Thunderbolt 5 represents a significant jump in bandwidth compared to previous iterations. While Thunderbolt 4 provides 40Gbps of bidirectional bandwidth, Thunderbolt 5 offers up to 80Gbps, with the ability to boost up to 120Gbps for specific display needs. For video editors and colorists, this increase ensures that high-resolution, high-frame-rate video signals remain stable without the latency issues often associated with external hardware expansion. This development follows industry trends toward more flexible, decentralized hardware setups where powerful I/O capabilities are no longer tethered to large, fixed-chassis workstations.
Technical Compatibility and Integration
The Io Xpand is designed specifically to support AJA’s range of KONA and Corvid cards. This compatibility is critical for broadcast engineers and post-production facilities that rely on these specific cards for tasks such as:
- KONA cards: Used for desktop video production, including editing, visual effects, and graphics workflows.
- Corvid cards: Often deployed in OEM-integrated solutions and high-density broadcast servers.
By moving these cards into an external chassis, studios can upgrade their computing hardware—such as moving to the latest Mac Studio or high-end PC towers—without needing to replace their existing, specialized I/O cards.
Comparison of Connectivity Standards
The following table outlines the bandwidth capabilities relevant to current professional video workflows:
| Connection Type | Maximum Bandwidth | Application |
| :— | :— | :— |
| Thunderbolt 3 | 40Gbps | Standard 4K workflows |
| Thunderbolt 4 | 40Gbps | Standard 4K workflows + improved stability |
| Thunderbolt 5 | 80Gbps | High-frame-rate 8K, uncompressed I/O |
Future Outlook for Modular I/O
The introduction of the Io Xpand signals a shift in how AJA approaches hardware longevity. As workstation lifecycles shorten, the ability to decouple expensive, specialized PCIe I/O hardware from the computer itself protects capital investments. Future updates to this technology will likely focus on further reducing the footprint of these chassis while maintaining the thermal management necessary for the intensive processing demands of modern 8K and HDR broadcast standards.
