I noticed that the tag sdd (7 questions) is for solid-state drives, according to the questions. However, the tag ssd (1,775 questions) is the actual tag for that concept. The tags should be merged into a new tag, solid-state-drive. Why a new tag? Because we don't want other users to accidentally create the sdd tag again, so that both tags go to a longer, easier-to-understand form.

I created a synonym from sdd → ssd and retagged the existing questions.
I can see how solid-state-drive would be nice to have, but people usually call these "SSDs". I'm not sure a complete retag from ssd to solid-state-drive makes sense though—only if there is a synonym that automatically leads to the longer form.
