    Can you TRIM too much?


    I've set up my fstrim to trim daily(at least I hope it doing it) but I also do a sudo fstrim -v / and /home before I shut down my computer for the day. So, will this cause any problems or is it ok to trim more often with an SSD?

    From taking a quick look too much TRIM can lead to write amplification.

    I say looking to future the real answer is the drives controler managing the drive, some of the newer drives have onboard management. Like when I was dealt with SANs all the time the highend controllers had hot-spot management built end to move content from over highly used sectors around.
