Does anyone know what the story with file systems and SSD's is?
Google did made it clear that some tuning makes sense for SSD's, but did not make it clear whether the various file systems are more or less suited to SSD's.

Samsung is working on a log-structured file system designed with SSDs in mind called F2FS[3]. There is also NILFS (also log-structured) which has been around for awhile[4].
I would stick with Ext4+TRIM for now on a personal laptop.

These types of filesystems are intended for when the kernel has access to the raw addressing of the flash chips themselves, such as on some cellphones and embedded devices. They handle stuff like wear leveling, and deleting blocks.
