January 23, 201511 yr Hello, I've been using this for a little while , so figured I could package it up for others to use. This is the Linux kernel module and utilities for Samsung's F2FS (Flash-Friendly File System) that I built for installation on Unraid 5.0.5 This is a NAND flash optimized filesystem, more information here: http://en.wikipedia.org/wiki/F2FS http://lkml.iu.edu/hypermail/linux/kernel/1210.0/03173.html I've made two packages, one is the kernel module, and the other a slackware package of the latest F2FS-progs (v1.4.0). They can be downloaded from my dropbox: https://www.dropbox.com/sh/8jwlykfup902h2p/AACiIuxR0CVtaRgV4fuF9jbUa?dl=0 You will need to untar the kernel module from the root directory, and it'll install in the proper path. The utilities package you can install with installpkg . You can either modprobe -a after installation so the module registers, or specify the filesystem type in the mount command (-t f2fs) for the module to load. You could always autoload the module as well.. I've been using it for a while on SSD drive that aren't cache nor array and are mounted separately to host some applications I run on the server. One advantage of this FS on NAND/SSD/Flash is its ability to do HOT/COLD data separation which can reduce WAF (Write Amplification Factor) up to 74% to make the SSD faster. ( see ) The default filesystem format (mkfs.f2fs) enables the default cold list which is filename extension based and contains all the popular media file extensions (including mkv) see line 27: https://android.googlesource.com/platform/external/f2fs-tools/+/e1a8e74e66682503dfdc497ccbb5900eede0ccaf/mkfs/f2fs_format.c
