It's not 2x M2 ....... it is using the M2 Drive as a Cache (for the 2TB HDD drive) and C:\ Drive
using Intel's Smart Response Technology ,which uses 19GB-64GB for Caching , the rest is usable for the OS as C:\
I also use an old 60GB SSD for caching my 2TB Raid 0 Array on my X99 system.
I found a picture on ifixit that shows the M.2 installed and the placement of the Wifi card. Dell is copying off of Apple in pretty much making their version of the Macbook Air. The only question is if you can increase the M.2 to a larger size if you are not storing items on a NAS on your network or some other cloud service. This is the link to let you zoom in and see it better. https://d3nevzfk7ii3be.cloudfront.ne...ZNfTeLlh1.huge
