Ive been deep in to implementing macOS CI workers on AWS where that isn't an option (or rather, it is an option, but it is unsupported and Amazon only buys Macs with the smallest possible SSD for the given configuration). So your options are to pay an arm and a leg for fast EBS, or pay an arm and a leg for a pro or max instance with larger internal SSD.

But on Linux there are better options.
