Samsung builds new Linux file system for flash storage

Samsung has a developed new file system. The f2fs-filesystem can be intigrated in the Linux kernel and should be optimized for reading and writing data to flash memory.

According to Samsung, who released the source code of the f2fs file-system, the new file-system should remove the shortcomings of the known file-systems as ext4 and exFAT regarding flash memory. F2fs, an abbreviation for flash-friendly file system, contains a log structure with various optimizations that would perform better in reading and writing data  for example to SD cards, SSD and flash modules. Also cleaning algorithms are included in this file-system.

F2fs can be included in the Linux kernel, according to Samsung it is to implement or adapt in practice. Furthermore the f2fs the tool is now available on SourceForge, which is intended to f2fs-partitions and mount it.

Samsung’s new file-system should be able to be used in Android devices that usually run from a flash storage. Whether the f2fs will be a success, must be awaited; Samsung tried previously to introduce it’s robust filesystem  and to implement that on the Galaxy S smartphone’s, but the performance of rfs proved to be substandard. With the introduction of the Samsung Galaxy S II samsung chose for the ext-4 filesystem.
