Why is this weird? “Apple” used to be the generic word for fruit in many different languages, it wasn’t until recently that it took on the meaning of a specific type of fruit. I don’t think calling potatoes “fruit of the earth” is at all strange. The English equivalent to this is the word “pineapple” – a fruit that kind of looks like a pine cone.
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.
