IdeaPad 330s-15ARR SSD location


I’m thinking about buying this laptop but it isn’t very clear wheter the ssd is an m.2 or full sized, so I know what to buy to upgrade. Does anyone know what type of SSD this laptop uses


This is the item model number, according to Amazon:


Lenovo Ideapad 320 15IKB Machine number 80XL033MIN, 8GB RAM but only 4 GB detecting.



I have Lenovo Ideapad 320 15IKB with Machine number 80XL033MIN, 8GB RAM (4GB Removable + 4GB Non-Removable), 1TB HDD, Windows 10 Home.  Two months ago my 4GB RAM (Removable)  stopped detecting and working. So I complained in customer care about replacement. 

But after replacement and after 2 months, I am facing the same problem again.  So I complained again. But I think engeneer will replace RAM again and I can face the same problem again in the future. This is not a permanent solution.  What should I do now? 


Can there be a motherboard problem? Because in diagnosis results there is no problem in the motherboard and without detection of problem engineer is not going to replace the motherboard. What should I do?


Thank You.
