The specs list up to a 2 TB M.2 SSD. There is no restriction on the placement of the drives. That should work fine.
Hi, I have recently purchased an Alienware m17 R4 with only 1TB SSD. I am planning to upgrade and buy an additional SSD for the 2nd slot. My question is can I add a 2TB SSD on to the 2nd slot with my first slot staying at 1 B?   Much appreciated. Thanks.
