Obligatory text:
The reason TRIM exists is because filesystems tend to have the idea that they are ran on a normal HD, which among other thing means that the SSD always gets incorrect flags on files(apparently a issue related to deleting files and where to allocate files).
Another problem is that the garbage collection now takes a back seat from trim, even if the garbage collection is several magnitudes more importantan than TRIM.

But back on the issue: I heard whispers about btrfs planning some SSD flags, but does there currently exist any project that just forks a filesystem, and adapts it for SSD use?
