RAID redundancy means that your volume is protected from an ordinary drive failure. In normal situations, your data will remain fully available even if one disk fails. So it is part of the healthy status, and you don't need to replace a drive.
But by saying "ordinary drive failure" and "in normal situations" I am pointing out that you can't depend on RAID as a backup. There are several scenarios where the RAID redundancy won't protect your data. You need at least one copy on another device to do that.

- Oh ok great thank you. Sorry if it was a dumb question. I tried to Google it and searched this forum but nothing was coming up explaining what it meant so I went on standard definition of the word. Thanks for explaining it. Appreciate it.
