I have read that you should not store /tmp on a SSD, because the frequent writes will shorten the lifetime of the SSD.  But what about /var/tmp?Is it reasonable for /var/tmp to be stored on a SSD?  Or should we avoid having /var/tmp stored on a SSD, to avoid killing the SSD prematurely?
Is it OK to store /var/tmp on a SSD?
directory structure;ssd;tmp
While it is true that all flash based storage devices have a limited number of writes before the transistor insulation breaks down, it's not as bad as it was when SSDs were first introduced years ago.Basically due to the fact that most modern SSD's employ wear leveling and are based on NandFlash, burning through a drive is not a problem like it used to be. You shouldn't need to worry about it. A SSD with constant writes will still outlast any rotary hard drive.
