yep, a modern [2017/18 ] machine small main drive big storage drive,it was replaced by another one with Windows 10.
to fit on your main drive I would be looking at Anti-x, Lubuntu, Alpine or Bodhi with a first choice Lubuntu, then anti-x [personal preference]
you have another option and that is to multiboot, leaving windows on the small ssd and installing Mint LMDE or 22 [LMDE is lighter and slightly faster] to the 1TB drive.
