Is RAID still needed? (programming.dev)

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?

Unlike hdd, I never experienced graceful disk failures on ssd. Instead, they just randomly decided to die at the most inconvenient time. Raid 1 saved my hide a couple times now from those ssd failures.

Yep. While it has been decades since I had a home SSD failure. But I have had 2 SSD failures in the last 10 years in server hardware. In the first case it was RAID striped and I needed to restore from backup. In the second case it was part of a raid 1 array and I just requested a replacement and got on with my day.

In my house, I have non raid SSDs on my own PC. But important stuff is on my NAS made up of 4xHDD drives in raid 5 (that also has the important folders backed up to an encrypted cloud).

RAID still has a place in an overall data security solution. Especially for servers that you want to keep up.
