So I have boot on the SSD and swap on the HDD then the rest of the SSD is lcmcache pool. And the spinner is my main drive as a single partition. So far this has worked nicely but there are time when you do some big writes you feel the fact there is a spinner under the hood. I could likely resolve this by playing with write cache settings. But the way I am using this its not usually an issue. Definitely see a big change on commonly used files vs infrequently used files.
