Msi ge72 apache 235 ssd type?

Hello! I am going to be purchasing this laptop here in about a week:
https://www.amazon.com/gp/aw/d/B00SVLJS7G/ref=ox_sc_act_image_1?ie=UTF8&psc=1&smid=A2TC87EJKQMY9O
Now they don't have the actual model number listed but what I gather from the specs is that this is the MSI GE72 apache 23, But it could be one of the other 2 models of the 5th gen. GE72 Apache as listed on the msi website. So my question is what type of ssd's does this model take? I've watched some videos of the 2QE ,2QD etc but not this specific model. Those have 3 m.2 slots and I'm wondering if this has the same. This model is upgraded with a ssd already but I'd like to purchase another but not sure what kind it takes and haven't found a compatibilitylist anywhere. I need to know exactly what type ssd this takes. Are they SATA III, or pci express 3.0, type 2280 or what? Thanks for any help!
