Samsung has just introduced a new File-System called F2FS (Flash-Friendly File-System) which is specially developed and optimized for NAND storage. Samsung has also open-sourced their new File-System by contributing the code to the mainline Linux Kernel.

Samsung Electronics has been the world's-largest memory chip maker since 1993. In 2009 it started mass-producing 30 nm-class NAND flash memories. It succeeded in 2010 in mass-producing 30 nm-class DRAMs and 20 nm-class NAND flashes, both of which were the first time in the world.

You can read the full description given by Samsung on the new F2FS below.

“NAND flash memory-based storage devices, such as SSD, eMMC, and SD cards, have been widely being used for ranging from mobile to server systems. Since they are known to have different characteristics from the conventional rotational disks, a file system, an upper layer to the storage device, should adapt to the changes from the sketch.

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.

Because a NAND-based storage device shows different characteristics according to its internal geometry or flash memory management scheme aka FTL, we add various parameters not only for configuring on-disk layout, but also for selecting allocation and cleaning algorithms.”
