ReiserFS is the standard FileSystem type designed by Hans Reiser. Future Technologies choose ReiserFS in 2000 as the first step in the FTOSX project because it is journalized, faster and the best space efficient FileSystem ever made. When you create a new file on DOS or VFAT (MS Windows) filesystem, after months would be necessary to 'defrag' your filesystem, with programs like SpeedDisk from Norton Utilities or others. If you use 'ext2', the normal choice for common Linux Distro, you may lose your data after a power fail. In you are using a classical UNIX, is logical to suppose that the classical 'lost+found' criteria is used (like in ext2), and your files are in danger if serious electric power fails frequently. ReiserFS solves all these problems ... in a definitive mode, because any new file created is automatically append in the filesystem, in use and the inodes belong to DB. There are more ...

With ReiserFS you don't need to check your filesystem.   For example, 4 Hard Disk with 60GB each one may take about one hour for a complete check ... after a powerfail or a periodic checking like happens for ext2. There are more .... Your entire system offers more performance on the same hardware, because ReiserFS is a filesystem using a plug-in based object oriented variant on classical balanced tree algorithms. No other FileSystem offers these feature and performance. With FTOSX and ReiserFS, your data is safe as never before. For additional info about ReiserFS please visit Namesys.com
