Somebody please explain about F2FS

[mehrshad.shafaghi]

Hi, I've been reading that many of the new roms are supporting F2FS. Can somebody please give a brief explanation about it? What is the difference between F2FS and ext4? Which one is better? How to change the file system? Thanks in advance.

well actually f2fs is an improvement but not an absolute solution
pros :
-improved write rates
- very improved random 4k read/writing ( ext4=7000 iops read 4000 write ; f2fs: 10000read/8000write)
- excellent filesystem for small files reading
-SQLite operation rate improved (ext4: 2000-2500 op/s ; f2fs: 2500-3500 op/s)

cons :
- slightly decreased sequential read (big files);
- #only on this device , noticed higher latency on opening apps (opening 10 apps on disco mark ; ext4: 4-6seconds ; f2fs: 7-8seconds)
- need modification in the rom's ramdisk to allow mounting f2fs partitions
-need f2fs compatible kernel
these are the results of my observation and benchmarking during a few months on f2fs , I finally came back to ext4 because of the latencies )

Hi @aaz03,
Could you explain what modification we need in the rom's ramdisk to allow mounting f2fs partitions
