Hello i’m starting a project i’m building a nas server this will be my first ever nas but im just confused about raids. After doing a bit of research if a drive fails and you have a extra drive in your nas your data is safe. But i also seen online if 2 drives fail and you have one extra drive your toast data lost?
Just need infomation how raids work and the best way to secure data if hard drives fails
