You may use ext4 or btrfs as they both support TRIM. Be sure to add the
"discard" mount option to your /etc/fstab as it will not be automatic
because there is fear by some kernel developers that some drives have
bad TRIM performance. I have not seen this on consumer drives though and
you will not have a problem with your brand new SSD.
There is one catch. LUKS encrypted partitions do not support TRIM; even
if they are ext4 or btrfs underneath. I would also say LVM and RAID do
not support TRIM either, but as of 2.6.37, they both do.
