Tough. At large capacity, HDDs are still quite cheaper than other storage devices, and still plenty of use cases where the "read speed" is plenty. For me though, I don't use a HDD anymore. I can do with some storage capacity, such as for having "several" modern games installed. But with fibre-optics availability increasing, with which there is a data transfer rata around the same as HDD "read speed", not a point for me to have a HDD, from which transferring 100 GB to the game drive would take some 15 minutes - which is not that much, but with a newer SATA SSD, that would be 3 minutes, or for a number of games the SATA SSD is still plenty good to run a game from directly.
Shouldn't be too bad for these companies though, as they are selling SSDs too, and the size of software isn't really decreasing.
