ZFS is one of the most sophisticated file systems available and it outclasses any other file system when it comes to speed, efficiency and stability. The speed at which info is processed on a server employing ZFS is much greater, so not simply will any sites hosted on the machine be read and executed much faster, but also backups could be produced more quickly and more frequently without affecting the efficiency. Moreover, ZFS uses checksums - digital algorithms which are employed to discover corrupted files. Anytime the file system finds that there's a problem with a particular file, it fixes it by using a good copy from another disk drive within the RAID. Both the checks and the repairs are carried out right away, so the data stored on ZFS-based machines will be safe at all times as it practically cannot get corrupted. Another advantage of ZFS over other file systems is that there's no limit for the total amount of files that could be saved inside a single account or on the server as a whole.
