Of course there has been improvement in absolute terms, but our current state is much more than just that, which skews the results when thinking about where we are. The opinion is definitely not popular on hackernews, but I still want to throw it out there.

Cheap SSDs can tank below 70MB/s after cache, which is less than a gigabit connection, so it can totally affect your performance even in the smallest local networks.

You don't have to sustain writes for long at all to start seeing the compromises hidden in cheap SSDs, especially if they're using their TLC as SLC cache, in which case you run out faster and faster.
