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."

But a bit more seriously though, this is a good thing. It's disappointing that when it comes to flash media, no suitable file system has gained popularity and we're still stuck with FAT. Well, ext2, too--


The thing here is that any block device filesystem will do for external media due to the hardware FTL (flash translation layer -- converts flash into a block device).

The post implies that this filesystem is to be used as a block device and not a mtd device. What confuses me is that they compare this to log structured filesystems, but those are usually used in mtd devices (which lack a FTL).

So what is the use case specifically for this FS?
