I'd like to see the real prototype myself: those connectors on top of a PCB seem too thick to fit into an EC slot - but there have been SSDs made in that form factor.
Edit: nevermind, he found a thinner connector. I should've read the Indiegogo page before commenting :)
Other than that, this adapter would be great for any laptop with an ExpressCard slot. I can't believe no one's made one before. Kind of late now that new laptops don't have the port, though.
It was! I had to remove the entire ExpressCard cage on the X230 I was using for testing. However, as noted in your edit, I've since slimmed the drive down further. This is what it looks like now: https://i.imgur.com/A0XEkW5.png Perfectly fits the EC spec.
