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?

    And what about the RAID controller itself? Does it not add complexity and another point of failure to the whole system?

    This is why people prefers software raid these days instead of hardware raid.

      That does not address the point made. It doesn’t matter whether it’s a complex hardware or software component in the stack; they will both fail.

        Yes, I didn’t address the point made, just want to mention that people are increasingly avoiding hardware raid these days.
