Correct name of the laptop inner port / bay

Question

what is the correct description for this inner port of my laptop? What is it for?

Thanks!

Answer 1

A quick google of the model number suggests its a thinkpad edge E330, and looking at the service manual, it suggests its slot that could either be for a PCI Express half mini card or a msata port.

Looking at the red book, and the potato quality images - most of the models of this SKU seem to have optional second PCIe port so that's certain.

I suspect it would work for msata too, but there's no clear indication that it will certainly work, but there's a few reports of successful upgrades
