We're excited to release a new specialized GitHub Actions runner optimized for I/O-bound workflows. This new runner is designed to handle workflows that are bottlenecked by disk I/O, such as those involving large file transfers, database operations, or other disk-intensive tasks.

The new I/O-optimized runner comes with fast local NVMe SSDs for higher IOPS and disk throughput than the traditional runners. They are configured with a local SSD as the write cache, and the reads are distributed between the EBS root volume and the local SSD.

They are available now in beta via the nee -io label for both Intel & Arm:
