If you have any experience with how SSD work/behave on FreeBSD, please write it here. Specifically I'm interested in how it works with different filesystems. I know popular way is to use SSD as a cache device for ZFS, but how would it perform if it actually hold ZFS pool; Does ZFS support TRIM? Or just UFS? Is ahci all that's needed for TRIM support? Is there any write degradation over time using it on UFS filesystem? I've heard lots of speculations about write limits, but would be curios to hear actual anecdotes from people who had run into these problems. I was planing to use SSD drive for pretty much everything except /home and something extra that comes under ZFS pool. Would it be wise to run swap, swap-mounted/tmp, /var on SSD? What about constantly building stuff from sources? How would that all affect SSD lifespan? So please, if you have any experience with these cool devices, let us know!
