Hi!I'm planning to buy a DELL INSPIRON 14 5415(5500U, 8GB, 256GB) laptop, but I would like to know, exactly what kind of SSDs does it support. More specifically, does it only accept NVMe M.2 drives, or also SATA M.2 drives?Is it M keyed?  I'm also planning to upgrade the memory when I get it, what memory brand is the most likely to work with it?Thanks for the answers in advance!
