Ironically, "solid-state drive" was also misleading, because "solid-state" was an industry marketing term to differentiate anything using exclusively semiconductors from any older technologies, such as vacuum tubes. So a standard HDD, based entirely on semiconductors and not vacuum tubes, would indeed be "solid-state" by those standards, but I for one understood a "solid-state drive" to be differentiated by no moving parts. Vacuum tubes did not, per se, move a lot. Not like an HDD platter or head.

Also regarding child comment, how did we already get to slurs for those with developmental disabilities? Can we avoid those, please?
