Partner organization:

As SSD are becoming more affordable they are also becoming more widespread on
laptop and desktop computer. Modern SSD supports the TRIM functionality. This
functionality delays costly erase operation to speed up performance ; these
erase operations are then executed by batch (this is SSD equivalent to
defragmentation). SSD can only run at their full potential if this
functionality is also supported by kernel and/or userland on the OS. Sadly TRIM
support by kernel is not optimal yet. Erase operation are not launched
automaticaly and this impacts overall SSD performance.

A cron script written at setup phase could launch fstrim program each night;
this program performs the erase operation needed not to struggle the SSD.
