Does anyone know how to get Linux to support TRIM? I just reformatted my SSD and would hate for it to become slower just because of deallocated blocks.

According to the linked wikipedia page on the TRIM command, Linux has supported it "since Feb 2010", so I would imagine that anything running the 2.6.32 kernel would correctly utilize that feature if your drive supports it. Please correct me if I'm wrong.

The article says that the "latest, greatest Linux kernels should beware", so I don't know what to think :/

Parse it once more: "Operating systems earlier than Windows 7 and the latest, greatest Linux kernel should beware"

Translation: latest, greatest Linux kernels support TRIM.

Ah, "earlier than (Win 7 and the latest kernel)", rather than "(earlier than Win 7) and the latest kernel". Thanks, looks like I'm covered, then.

EDIT: Apparently, Ubuntu is one version behind TRIM support.

Looks like you'd need the Linux 2.6.33 kernel:

It also requires filesystem support. ext4 was the first support it.

I believe btrfs, nilfs2, and xfs support it now as well.

This guy lists some good starting points: http://cptl.org/wp/index.php/2010/03/30/tuning-solid-state-d...
