My two cents on XFS

The XFS Filesystem was developed by Silicon Graphics some time ago. 1994, to be correct. I loved it because of its speed and reliability. Its B+Tree structures made it extremly fast with directories and the maximum filesize is amazing as we are talking about Exbibytes, which is more than 9 million Terrabyte!! As a bonus it is even non blocking. In other words, great work SGI guys.

But XFS also got its issues. One of them is its delayed writing of file data - if it crashes, you’re pretty fucked. In theory, it should not crash, but you know. Metadata is written first, then follows data. So it is possible that you will find zeros in the middle of your data if it crashes. The file is broken.
