Would be nice to know what version of PCIe. Unfortunately, even the original blog post doesn't say.

I'm guessing 2.0 x1 lane, but I guess the SSD benchmarks don't rule out the possibility of only PCIe 1.0 x1. Maybe an enterprising person, such as an author of articles about such things, could actually look up the SoC specifications and check what it can support. That would be a really cool and journalistic thing to do, I'd say.

It'd be sweet if they socketed the USB2 controller, on higher-end versions of the board, specifically so that people could easily swap it out for this sort of mod.

Anyway, while this is a cool hack, it should be noted that some of the RK3399-based boards (such as the RockPro64) have a x4 slot built right in.
