Update = User reported that the SSD is installed in the Inspiron 16 7610 and everything is good.
I just purchased an Inspiron 16 7610 Plus.  Main considerations were screen size (very nice) the PC Magazine Editors Choice award, and the review that said adding a second drive would be easy as the laptop has 2 m2 slots.  It also said the slot was PCI 4 which will accept up to 2 TB SSD drives (a definite plus) I have been trying to determine what SSD to buy and called Dell.  The rep said that the maximum size supported was 1 TB, not 2 and offered to sell me a TB PCI 3 SSD for only slightly more than a raft of 2TB PCIe 4 drives (so not too interested). This leaves me back at the start. Who is right on the capacity - Dell sales or the editors choice review? And which company is the best balance of price and performance.  I'm not gaming so I don't need the fastest on earth, but a reliable drive that doesn't cost a mint and has reasonable speed that fits would be nice. Any help out there?
Inspiron 16 7610, 2nd hard drive?
