Samsung developed a new file-system that's optimized for storage devices with multiple NAND flash memory chips. Called "Flash-Friendly File-System" or F2FS, Samsung's newest creation has been submitted to the group governing the Linux kernel, and an implementation of it on derivatives such as Android is possible in the near future. F2FS is designed to take into account the "internal geometry" of NAND flash storage devices, using a log structure approach that overcomes shortcomings of file-systems designed for older spinning-disc physical media (such as floppy, hard drives, and optical discs). There's also promise for F2FS, particularly in future high-density servers using enterprise SSDs.
