With a NAS with M.2 SSD slots, you can create a very fast cache memory. When you work with your NAS a lot, you have a number of files and programs that you use several times a day. An M.2 SSD cache processes this up to 2 times faster, like when you move many large files internally. With an M.2 SSD NAS, you can work more efficiently, finish large tasks faster, and you're less bothered by delays when you use the NAS with several colleagues.
