I didn't follow this thread, but IIRC I read something about "not to
write to often to SSD"? So you take care regarding to noatime etc.?


"Reliability and lifetime 	SSDs have no moving parts to fail
mechanically. Each block of a flash-based SSD can only be erased (and
therefore written) a limited number of times before it fails. The
controllers manage this limitation so that drives can last for many
years under normal use.[79][80][81][82][83] SSDs based on DRAM do not
have a limited number of writes. Firmware bugs are currently a common
cause for data loss.[citation needed] 	HDDs have moving parts, and are
subject to potential mechanical failures from the resulting wear and
tear." - Wiki

You'll make your Linux less reliable by handling log files in a dirty
way, to get a longer lifetime for a SSD drive? Nobody really knows how
long they'll last, but it's said they have a longer lifetime than
mechanical drives?

Perhaps not a good idea.
