Hi, I've bought an OCZ Vertex2 E (120 GB SSD) and installed FreeBSD i386 stable/8 on it, using UFS (UFS2, to be exact). I've made sure that the partitions are aligned properly, and used newfs with 4k fragsize and 32k blocksize. It works very well so far. Now, the only thing missing would be TRIM support for UFS. I did some research and found the following patch: http://people.freebsd.org/~pjd/patches/ufsdel.patch Apparently that patch is supposed to make UFS use TRIM, among other things. However, the patch seems to be rather old (time stamp says 2007-02-03), and nothing has been comitted to current or stable so far (I've grepped through the past 12 months of SVN logs, after TRIM support was added to ada(4) by mav@). So, my question is, are there plans to add TRIM support to UFS? Is anyone working on it? Or is it already there and I just overlooked it? Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
