The endurance seems to be high enough to handle about 1 drive write per day which is much better than most SSD products. Leveraging RAM in a server reduces storage activity in a multi-user setup.

Many modern NAS boxes now have M.2 slots for a SSD. The WD Red is an ideal choice given its high endurance. A busy NAS server is better off with maximum RAM to reduce the wear and tear on hardware generally. RAM has almost unlimited endurance.
