I was going to suggest 'relatime' instead of 'noatime' until I read this:
http://thunk.org/tytso/blog/2009/03/01/ssds-journaling-and-noatimerelatime/

See also:

* man mount
* http://en.wikipedia.org/wiki/Stat_%28Unix%29
	"... Reading a file changes its atime. File systems mounted with the 
noatime option do not update the atime on reads, and the relatime option 
provides for updates only if the previous atime is older than the mtime 
or ctime. ..."

I have an 16G SSD on my Mini9 with encrypted LVM and relatime and it 
works great.  I love the no-internal-moving-parts thing.

Later,

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
