It's not about saving money, more about convenience and noise.
With large SSDs it seems alluring that one could have the majority of hot data on SSDs, essentially making the cold data even colder.
As you mention I could split my data in two, but that's a chore. If I need new data on the hot pool, I might have to first decide what got cold enough to move to the cold pool if there's not enough room left on the hot pool. That means I have to wait for that before I can save the new stuff on the hot pool. Searching for stuff means searching both places etc.
I forgot I stumbled over AutoTier[1] which could work, but it seems abandoned so again, not ideal for precious data. And it's FUSE based, so performance is likely not the best.
