I think it had its uses in the past, specifically if it had the memory backup to prevent full array rebuilds and cached data loss on power failure.
Also at the height of raid controller use (I would say 90s and 2000s) there probably was some compute savings by shifting the work to a dedicated controller.
In modern day, completely agree.
Yeah, it’s not really new. In the movie Falling Down from 1993 (weird, I thought it was late 80s) has the whole scene where he’s complaining about the difference between the advert and what you’re served in a fast food place (well also that they wouldn’t serve breakfast because it was like a couple of minutes late and almost certainly had some still hot breakfast around, but that’s another story).
It’s been this way for a long time, all over the world. I’d be amazed if this turned into a world changing case after all this time.
