Samsung has developed a file system optimized for NAND Flash storage. F2FS (“Flash-Friendly File-System”) is based on a log-structured method, but could be used on rotating media, i.e. spinning hard discs. Samsung isn’t patenting this development, in fact they have sent it to the Linux community for inclusion in the Linux kernel meaning it could be built into Android sometime in the future – Phoronix
