ZFS is one of the most advanced file systems available and it outshines any other file system in terms of speed, overall performance and reliability. The speed at which data is processed on a server using ZFS is a lot higher, so not simply shall any websites hosted on the server be read and executed faster, but also backups can be generated a lot quicker and more frequently without affecting the overall performance. Moreover, ZFS uses checksums - digital algorithms which are employed to identify broken files. Anytime the file system identifies that there's a problem with a specific file, it fixes it by using a good copy from another hard drive within the RAID. Both the checks and the repairs are done in real time, so the information located on ZFS-based machines shall be safe at all times due to the fact that it practically cannot get corrupted. A different advantage of ZFS over other file systems is that there is no limit for the amount of files that may be saved within a single account or on the hosting server as a whole.
