I have M.2 SSD with PCIE adapter and Im quite satisfying with this one. I know that M.2 SSD is much faster than SATA 3 SSD but I dont see any benefits at all. All LR catalogs and files are located in HDD. The speed is extremely fast but I really really dont see any differences between M.2 and SATA3. Did I missing something or it's just meaningless to get faster one?
