How to understand that a second disk can be inserted into a laptop?

Question

laptops

The question is probably childish and naive, but still. Can I somehow understand whether it is possible to insert a second disk into a laptop before buying? Googling like
"MSI Prestige A10SC insert second disc",
"MSI Prestige A10SC add second disc" is of
no use. Perhaps the manufacturer somehow indicates this, or are there directories by which this can be understood?
By second drive I mean HDD. So that the axis is on the SDD, and the working files are on the HDD

Answer 1

You cannot insert a second disk into your laptop. Because there is not even the first disk. It uses an SSD in the M2.
As for a general question. If the laptop has a CD drive, then it can be replaced with an hdd by purchasing such a holder.

Answer 2

The easiest thing is to look for reviews and photos of a laptop with the cover removed.
