Any modern ssd uses all unwritten space for wear
leveling.  If your ssd needs room to breath (not all
do, see the new Intel DC S3700), simply do not
allocate all the space from the drive to partitions,
leaving free cells.

And most modern ssds and OSs can use trim
(for sata, unmap for sas), to release any "free"
space back to the drive for wear leveling and
reallocation purposes.  The filesystem discard
option needs to be set appropriately (or defaulted
to).
