I am not sure but I thought it defrag automatically in newer versions of windows, correct ? I assume that so, or do not defraged anyway completely. Correct ? I see it that way and yes I need to replace HDD at last and I plan to do it asap really.
There is no point defragging a ssd as there is no head to move, zero seek time, doing so just uses up limited write cycles.
