Me and my friend were discussing this the other day about how he said RAID is no longer needed. He said it was due to how big SSDs have gotten and that apparently you can replace sectors within them if a problem occurs which is why having an array is not needed.

I replied with the fact that arrays allow for redundancy that create a faster uptime if there are issues and drive needs to be replaced. And depending on what you are doing, that is more valuable than just doing the new thing. Especially because RAID allows redundancy that can replicate lost data if needed depending on the configuration.

What do you all think?

Media failure isn't the only reason to back up. If you delete a file on a RAID array, it's gone on all disks. If you need to recover that deleted file, you can't recover from RAID. The same goes for formatting/damage of the file system, recovery from something wrong inside a database, etc.
