Linux "F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead."

From the KML, it seems some of the kernel devs are confused as well...

It seems that it does not do wear leveling and is designed to work with an FTL, but its as clear as mud to me.

I guess it will all shake out eventually. It does look interesting though:

FTL handles wear leveling, but introduces unusual performance characteristics: in-place updates become very expensive. In many cases this can be helped by file system doing copy-on-write instead of in-place update. I guess this is the idea.

That said, I thought Samsung has enough resources to proof read the documentation before submitting (at least use a spell checker). Comparison to similar file systems and some benchmark results would also help.
