In the mid-late 1980s we compiled and tested Amiga software on the Amiga entirely from RAM drives using rather expensive 2 MB RAM add ons, and then stored the updated source code on 3.5" floppy disks that had to be rotated out regularly because they regularly went bad.
Only towards the end of the 1980s were hard drives inexpensive enough to become commonplace. My first 65 MB drive cost $949 (ca 1989), and that is why we were using floppies and RAM drives instead. The RAM drives did survive reboots and crashes most of the time, which helped quite a bit as you may imagine.
