why do you waste time and not just store *anything* on the fast storage? that's *really* not a mysql / maridadb question

my doubt is... today i have myisam, aria, innodb and sometimes tokudb and spider at same server
how could i easily select what table should be stored at ssd or hdd array?
there's a "table space" to select if i want to use ssd or hdd instead of create table, and create symbolic links, or create table with data directory/index directory? i was thinking about something more easily understood like tablespace, but used by all engines something like
create table blabla table space ssd create table blabla table space hdd
what i'm doing today... i have many tables that i use normally and don't drop, these tables i can symbolic link to ssd or hdd, but all new tables i use hdd (they normally are temporary tables), i'm using innodb per file, tokudb i'm not using too much but i don't care about where it's today
anyone with experience to help or ideas?
