the more i use this laptop the more impressed i am.2 slots for ram, max 2x32gb.  2 x m.2 nvme drives and one 2.5inch sata port.  i did a lot of research on the nvme so let me save you time.  the max bus from both of the m.2 slots is x4, so you will NOT gain performance with raid0.Anyways, overall for the dollar this is packed with all the important bells and whistles.  it also has the best cooling out of all the laptops of ita class.  this will help you in the long run so you dont have to worry about throttling and the circuits burning themselves out.  this will give you overall performance no matter what you throw at it.only downside i have to put up with is the noise.  the airflow is extremely useful, but very loud.if you are on the fence, i can tell you this is the laptop to get.  unless you dont mind throwing in another grand, then get this with the  RTX 2080 and 4k display.but if you are looking for the best bang for your buck, well you found it here.
