Any business anywhere running Windows file servers is running NTFS for server storage. Any business running a Hyper-V virtualisation, including large cluster, is running their virtual disks on NTFS. There's an irony here in Microsoft's next generation file system being "ReFS", with "resiliant" literally there in the name. And it has such a history of bugs and unimplemented features it's not safe for use outside of specific scenarios. Edit: the link phendrenad2 posted has a comment about a "server destroying bug" in ReFS.

That thread [1] is 4 years old. Is there recent credible evidence of ReFS being problematic? 1. https://www.reddit.com/r/DataHoarder/comments/67h28o/bit_rot_detection_and_correction_on_windows/ https://www.reddit.com/r/DataHoarder/comments/67h28o/bit_rot...

  Microsoft's documentation still refers to recommending NTFS "for general use" and then list specific places it's designed for. Also listed features still not available often make it a show stopper: https://docs.microsoft.com/en-us/windows-server/storage/refs/refs-overview https://docs.microsoft.com/en-us/windows-server/storage/refs... Most Hyper-V admins will be familiar with this thread which is still completely accurate. This is relevant as it's "by design" and won't change or be fixed. https://community.spiceworks.com/topic/2286588-please-do-not-use-refs-for-cluster-shared-volumes-provided-by-a-san https://community.spiceworks.com/topic/2286588-please-do-not...
