It is a mechanism to > support round-robin usage of those cells. wrong, too. the drives firmware is responsible to round-robin usage of those cells anyway. it works even on (almost) full disks, too. with an OS that doesn't support TRIM, after a while the drive thinks that all sectors are in use as they have been written at least once. TRIM (capital letters) is a way for the OS to tell the drives firmware which sectors are no longer in use. round-robin usage is made easier if there is more free space available, but works even on completely full disks as the disk always reserves some space for internal use that is not visible on the outside. lookup overprovisioning.
