A write-focussed SLOG device can massively improve your write IOPS though, and is massively cheaper than having an "all-ssd" pool, while being able to approach it's normal use performance. If you have a sustained heavy I/O load, sure - going full SSD will be your best bet, but for most usecases, you only need peak IOPS performance in short bursts.
