I simply read stuff like http://www.anandtech.com/storage/showdoc.aspx?i=3531 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. > All I know is that two days ago I flashed my 160GB G2 with the > finally-no-longer-bricking-Windows and TRIM-enabling firmware, and that it > "just works". Fine. Does ext4 send TRIM already? AFAI understand the needed changes in libata are up to come with 2.6.33, correct? > You could also try btrfs with 2.6.32, if you're adventurous enough :) > (works fine here too) 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 ;-) Stefan
