Also the "cells" only have a certain maximum of write cycles: demanding a need for "wear leveling" over all cells on the SSD: Again, defragmenting shortens the lifetime because the cells adjacent to each other are repeatedly stressed more than the free unused cells.Ī deletion of a file does not result in freeing up cells, contrary of magnetic disks. Defragmenting causes loss of efficiency and speed. Writing takes longer and longer: writing causes a block of 64k to be freed before writing even when you only need to write a small file.
