My Nitro 5 Mid level gaming laptop, that I use for MSFS, came with one 500GB M.2 drive installed, and a slot for a 2nd one, as well as a bay for a 2.5" Drive.
I fitted a 2nd 1T M.2 and it is more than adequate for MSFS GA flying on and bigger HDMI1080P monitor.
I am guessing, by the time MSFS gets to a point where it can take advantage of a PC with more resources than an X-Box X, the cost of PC parts will have come back down to a sensible level, as well as being more advanced than today’s Hardware.
