This is how you can have fast machine boot and fast linux command execution, AND some important big sized partitions and logical volumes in your rotating disks transparently cached to the SSD to improve performance. This setup uses a Linux module called Flashcache.
You should not use such caches with programs that bypass cache (some KVMs with settings “no-cache” and similar stuff). You understand why. :-)
