I really think you're gilding the edges of those old memories. The software 20 years ago wasn't that great. I'd say it was on the whole a whole lot crappier than it is today.
It's just that we have much higher expectations, and our problem sizes have grown a _lot_ faster than rotating disk latencies have improved. People didn't worry about having a hundred megs of dirty data and doing an 'fsync' twenty years ago. Even on big hardware (if you _had_ a hundred megs of dirty data you didn't worry about latencies of a few seconds), never mind in the Linux world.
This particular problem really largely boils down to "average memory capacity has expanded a _lot_ more than harddisk speeds have gone up".
