The issue is that the speed -characteristics- are so very different between HDDs and SSDs. Not just the raw speed. Decent performance of anything with IO on an HDD requires that the IO is specifically structured to minimize seeks and maximize sequential access. That takes time and skill. If very few modern machines don’t have an SSD then it is understandable to simply skip this difficulty. That time and effort is often better spent elsewhere, and this is a valid tradeoff to make.
