f2fs-tools - Tools for Flash-Friendly File System (F2FS)
- Description:
NAND flash memory-based storage devices, such as SSD, and SD cards,
have been widely being used for ranging from mobile to server systems.
Since they are known to have different characteristics from the
conventional rotational disks,a file system, an upper layer to the
storage device, should adapt to the changes from the sketch.
F2FS is a new file system carefully designed for the NAND flash
memory-based storage devices. We chose a log structure file system
approach, but we tried to adapt it to the new form of storage. Also we
remedy some known issues of the very old log structured file system,
such as snowball effect of wandering tree and high cleaning overhead.
Because a NAND-based storage device shows different characteristics
according to its internal geometry or flash memory management
scheme aka FTL, we add various parameters not only for configuring
on-disk layout, but also for selecting allocation and cleaning
algorithms.
