It’s going to confuse everyday users
Call me a conspiracy theorist, but I believe this is the intention. I think big companies deliberately put in confusing and bad design to “test the waters” and see if people will still buy their products. It’s the same with the apple mouse charging on the bottom, or why companies keep making their logos uglier with each iteration. It’s a psy-op to condition the masses into accepting worse products without complaining.
A lot of “hardware raid” is just a separate controller doing software raid. I thought I lost access to a bunch of data when my raid controller died, before I realized that I could just plug the disks directly into the computer and mount them with mdadm. But yes, hardware raid seems a bit pointless nowadays.
