would negatively effect the life of a disk and performance of the

This is a potentially broad topic, and the correct answer probably
ultimately depends on how you decide to redo that process.
Is it polling for something (e.g. existence of a file or some state
change?). Polling is something you really ought to try to avoid.
Maybe some kind of notification would work better.
Could you change that process to just reuse it's memory (instead of
allocating and releasing space) between each run? If it's hitting
disk each time it's run, are you unnecessarily allocating a lot of
memory?
You'd probably get a much more thorough & better answer from the list
if you elaborated on what the ultimate goal of that repeating process
is.
