Nitro 5 Spin (NP515-51-85CS) memory and SSD upgrades

ArtD

Hello,
My question is about Nitro 5 Spin (NP515-51-85CS) model. Can memory be upgraded in this model? What is the maximum memory supported?
Can HDD be replaces with SSD? If yes then which one? SATA only? No M2?
These are the most important questions for me. 
Less important - is there a reason they still use HDD in their models? Money or other reasons?
Why not to add this info to the item description? I think it is reasonable to want to know about max memory and such.
It's hard to get direct answers from the companies these days. They try to shift responsibility to the communities and such unfortunately...
Thank you, Art.
