Laptop disk drives are all 2 1/2 inch.  The larger ones are only for desktops and towers.

Hi, @Yrys7 


Most likely since your notebook came with a 256 GB M.2 SSD, none of the parts are there to add a 2.5" drive.

So, before running out and buying a 2.5" drive, make sure the required parts to add it are there, or that you can find a place to buy them.  Many times the parts are impossible to find.


Below is the link to the service manual.


Chapter 3, page 19 has the parts needed to add a 2.5" drive.

(2) Hard drive brackets not available as spare part
(3) Hard drive connector/cable            L72698-001


It would be a whole lot easier and would also save battery power to just replace the 256 GB SSD with one having a larger storage capacity.
