I have had an SSD for about two years now and have never bothered enabling the discard mount option.  I left some of the drive unpartitioned so that some blocks would never be written to and thus, the drive should never run out of erase blocks.  About 6 months ago I did a benchmark and noticed that it wasn't quite as fast as it was when it was new ( though still plenty fast ), so I migrated my data off and reset the drive with an hdparm security erase, then moved my data back.  This restored performance to tip top.
