Looks very interesting but clearly not for the faint of heart.

Some RAID controllers and drives do this automatically now.  RAID controllers will have an SSD for
cache; “hybrid” drives have some flash with a spinning disk.

I used a hybrid drive in my laptop for a while.  As you might expect, it was definitely faster than a 
spinning disk but it didn’t “feel” as fast as a plain SSD.
