look into mount options for SSD's (discard option) and "fstrim" for 
maintenance. (read up on trimmimg - doing a manual trim before the drive 
reaches full allocation (they delete files, but do not erase them 
because erasing is time consuming so its an OS controlled operation) or 
auto trimming (which can cause serious pauses at awkward times) can 
prevent serious performance degradation as it has to erase before 
writing.  I am not sure of the current status but in the early days of 
SSD's, this was serious concern.
