I'd assert that it could make a better prediction for the majority of the files stored on your drive. For example, even if it was technically feasable to do with separate drives, do you know which files in the global assembly cache should go on SSD versus HD? Which pieces of your registry hive files? Which bits of your browser cache?

I don't use Windows so I don't have GAC or registry files. Browser cache always goes on the SSD because it's highly latency sensitive.

You say browser cache always goes on the SSD (I do that too, whenever there's no configuration to put it into RAM, which I prefer). Aren't you concerned about wear? If you stream high resolution video files from, say, youtube or twitch, you write gigabyte after gigabyte into that SSD.

Modern SSDs will survive hundreds of TBs of writes, sometimes even PBs. Techreport did a long endurance test with multiple drives:

I expect to upgrade for increased capacity long before I reach that.
