I also think Intel Smart Response is an interesting technology, to use an SSD as a cache for a larger HDD.
The idea of hot files on SSD and cold files on HDD, isn't new. It's integrated into ZFS as L2ARC, and has also been discussed on the Btrfs devel list. And even drive manufacturers are integrating the two in some drives, although they seem to have pretty small SSD capacities thus far.
I'd really rather not have to fsck around with some of my crap on a dinky ass SSD, I'd rather the file system or disk figure out what's hot and cold, even portions of libraries could be on SSD and HDD simply because some parts are often used and other parts aren't. Same for help files.
