[QUOTE="ForgottenSeer 97327, post: 1062869"] SSD's have a limited write cycle (depending on type and quality of the ssd this can vary). When (just an example) the write cycle of your SSD cell's is say 100.000. It means that you can write 100.000 times to that cell before it starts to provide faults. When you bleach deleted files they are overwritten with a value (e.g. low values or all binary zeroes). This bleach also counts as a write. So bleaching could shorten the life time of a SSD depending how often you bleach deleted files (overwrite them with low values). Also bleaching should not be nessecary because SSD's erases deleted cells automatically to speed up disk writes, This process is called garbage collection. [SPOILER="What SSD garbage collection really is :) "] Despite its name, SSD garbage collection has nothing to do with discarding files that are no longer needed.
