How often do you trim?

[sprout2287]

I am just curious as to the frequency of your ssd trims. I know I used to defrag once a week or so, but with no decrease in hdd life.

I'd imagine everyone's using wiper to do this. That's the only application I've seen as of yet.

IIRC this action (trimming) increases your performance, yet decreases the life of the drive (since there are a limited number of writes over the drive's life).

So the question stands, how frequently should I trim my drive? Should I wait to notice a decreased performance state?

Also, anybody have any reasons why I shouldn't run ccleaner regularly? Is it helping my system now that I have an ssd?
