Just for fun I asked ChatGPT-4 which was better, XFS or ZFS


Recommended Posts

This was the reply:


XFS and ZFS are both filesystems used in Unix and Unix-like systems, but they are designed for different use cases and have different feature sets. The choice between XFS and ZFS depends on your specific needs and circumstances. Here's a comparison of the two:


ZFS [ Zettabyte File System ]

    ZFS is a combined file system and logical volume manager designed by Sun Microsystems.
    It's known for its robustness, scalability, and data integrity features.
    ZFS supports features like drive pooling, data redundancy, automatic error correction, and snapshotting, which makes it excellent for data storage and servers.
    ZFS is more resource-intensive, particularly in terms of RAM. If you're running a system with limited resources, ZFS might not be the best choice.
    ZFS can be complex to set up and manage, and may be overkill for simple file storage use cases.




    XFS is a high-performance file system designed by Silicon Graphics for large amounts of data and was designed to be used on large hard drives.
    XFS supports metadata journaling, which aids in the prevention of corruption and accelerates recovery after a power failure.
    XFS does not offer built-in drive pooling or data redundancy features.
    XFS is less resource-intensive than ZFS, making it a better choice for systems with limited resources.
    XFS is easier to manage and setup than ZFS, but lacks some of the advanced data protection features of ZFS.


Overall, if you need a robust, highly reliable filesystem and have the resources to support it, ZFS might be the better choice. If you're looking for a high-performance, efficient filesystem and don't need the advanced features of ZFS, XFS could be a better option. Always consider your specific use case when choosing a filesystem.

Ouch.  ChatGPT misspelled set up.  It bothers me that setup is used as a verb when it's a noun.

XFS is easier to manage and setup set up than ZFS, but lacks some of the advanced data protection features of ZFS.


And while we're on the subject.  This is wrong too.  It should be "Shut down the system".

I don't know about you guys but all questions like this one, where you ask is this better than that, seem to be answered as a comparison and then "depends on your needs".  Has anyone ever got, "Oh yeah, you need to use this one for sure otherwise you're an idiot for choosing that other thing."


Waiting for AI to devolve into responses like "Only boomers use XFS."


FYI I'm sticking with XFS in my array, for now.
