What have you researched so far? What is your target machine and how will you be using it?

HOAS - HeadOnAStick has several good posts about it on BunsenLabs forum and also on Debian Forum.
I am under the impression that trim is pretty well integrated into the kernel these days.
The only thing I have said for awhile in these sorts of posts at #!, etc. is that if all you have is an ssd (as in my old eee901) - then if you need (or desire) a /swap, use a cheap SDHC for it. /tmp and /var can go there too, but I didn't and still do not. For the attached fstab sdb is a SDHC. /swap is on sdb1and is for an Asus eee netbox,
Here is my fstab I am not saying that this is the way to go.
## /dev/sda1
UUID=33e3701e-b81c-4bfe-82a8-c7950596b6cc / ext4 defaults,noatime,discard 0 1
## /dev/sda2
UUID=f0ffc849-9176-41b1-a573-fe96cf13bd68 /home ext4 defaults,noatime,discard 0 2
## /dev/sdb1 blue sdhc
#UUID=d1aa9137-4d35-4d6c-bfb9-ce2df60e3e85 none swap defaults
## /dev/sdb2 swap
#UUID=3143684f-1f95-4fc2-b9bd-72872789f2b4 /media/SDHC ext4 defaults, noatime,discard 0 2
I am thick-skinned, feel free to crituque.
