So i bought a Synology Nas DS920+ with 3 12TB Hard drives. Just created a Raid 5 with the system and just ordered a 4th hard drive to add to it. Should i switch to Raid 10 or any better options or stick with the Raid 5? Kinda new to this but have been researching and reading up on everything. Also, built my plex server on it as well as of now has 2tb of movies and such on it. Any opinions would be appreciated on what to do here, thank you!
