Fast Reset
The Amiga Fast File System (FFS) is a file system used on the Amiga personal computer. The Amiga Old File System (OFS) was too slow to keep up with hard drives. FFS differs mainly in the removal of redundant information. Data blocks contain nothing but data, allowing the filesystem to manage the transfer of large chunks of data directly from the host adapter to the final destination. http://wwwboinfnit/~falchier/carlosrx_v4_rel12_datasheetpdf.
History
FFS was introduced with version 1. 3 of AmigaOS in 1988.
With version 3. 0 of AmigaOS, born for the new amiga 4000 were introduced new FFS modes, called International and Directory Cache. Do you reset device frequently? Make your resetting fast!.
International mode allows FFS to handle filenames with international characters.
Directory Cache mode allows the filesystem to access hard disks more rapidly by creating a cache of directory contents. As any other directory caching based systems it used a certain amount of disk space to store the data.
Relatively recently MorphOS and the presently unreleased AmigaOS4 have introduced support for new FFS2 filesystem Or Fast File System 2. # reset DIU NET "busy" LOC = "j18" | SLEW = FAST ; NET "carlos4_output<0>" LOC = "h4.
Normal (or "ancient") FastFileSystem is outdated compared to more modern file systems; it lacks the reliability and advanced features of more modern offerings.
