When did computer manufacturers start putting more drive space on the D drive and less on the C drive and why?

    It's to keep the computer efficient.  By using a smaller SSD for the C:\ drive you end up with less software/data on that drive and therefore better efficiency is inherent in doing that.  You keep all of your extraneous software on the D:\ drive which allows the C:\ drive to operate at it's full potential in it's seek, access, read, and display cycles.  You have to be the one to decide how much "stuff" goes on the C:\ and what specifically goes on the C:\ and D:\ drives.

    C: drive is smaller, faster SSD, storage is on bigger but cheaper and slower HDD (D:)

    Are you referring to the fact that modern systems often now have an SSD for a C drive and a conventional HDD for the D drive? 

    If this is what you are noticing, then the reason is, it's very beneficial (in terms of performance/speed) to put the operating system on an SSD. But SSD's are both a lot more expensive and have a finite number of reads (shorter lifespan the more it's used). So most of the rest of your personal data is better put on the HDD. As faster aquisition is either not necessary, or the benefits from it being stored on an SSD aren't worthwhile, or even nonexistent. 

    For this reason, a secondary, D drive, is typically >1TB. But only expensive machines tend to have an SSD >500GB. As it's just not necessary for normal use.
