A question I just asked here regarding HDD hard drive thrashing has prompted me to give pause and think about SSD thrashing. IMO, thrashing (ie, rapid and excessive reads and/or writes) is never good and should never be tolerated. With HDDs, you know you're being thrashed because you can hear it, but what about silent SSDs with no moveable parts?
I can't help but wonder what sneaky tricks developers will hide in their applications once SSDs become more common (after the prices go down, for instance). Applications will be able to access your drive virtually all they want because you'll never know it's happening.
Therefore, it only seems plausible that some sort of drive access monitoring tool would exist to let you know when you're being thrashed. It could even prompt you and ask you to allow hard drive read/write permission whenever a particular process attempts to access your drive. Does something like this already exist?
