Why has the "hda" disk identifier been replaced by "sda"?
Wouldn't it be slightly wiser to keep hda for mechanical HDDs and sda for SSDs?

Re: Why has the "hda" disk identifier been replaced by "sda"?
Huh? This was never for hdd vs ssd. Historically the name was based on the controller, hd[a-z] was used for IDE, and sd[a-z] for SATA. There may potentially have been a correlation between IDE controllers being more common when HDDs were more common - thus a lot of HDDs getting hd[a-z] names, and as time went on more SSDs getting sd[a-z] names, but this is a coincidence, not a label of the type of drive.
