I simply read stuff like

http://anandtech.com/storage/showdoc.aspx?i=3631

and especially

http://thunk.org/tytso/blog/2009/02/20/aligning-filesystems-to-an-ssds-erase-block-size/

It's a moving target here, sure ...

As I know myself I will simply fiddle around with the settings and
re-copy my root-fs several times before deciding for one particular setup.

I will do some dualboot-scenario, my current hdd-raid1-based root on one
hand and the new ssd-based root on the other, both included in my
regular backups, sure.

Fine. Does ext4 send TRIM already? AFAI understand the needed changes in
libata are up to come with 2.6.33, correct?

Hmm, dunno. That's quite bleeding-edge and beta ... this machine is my
main workhorse that helps me to earn money so I don't want to risk too
much there. Maybe on a third copy of root-fs ;-)
