Most of the file systems in use today were designed in an era when rotating discs ruled the world. Well, as things have shifted more toward NAND flash-based storage in mobile devices the problems with older file systems have been more visible. Samsung has just tackled the problem by designing a new file system called F2FS that's geared toward flash storage specifically. What's better, it is open source and has been submitted to the Linux kernel. This makes it perfect for implementation in Android.
This isn't the first time Samsung tried to deploy a new file system. RFS was used on the original Galaxy S phones with catastrophic results.
