HN gets all bent out of shape about minor differences between btrfs and zfs. Like how zfs supports raid5/6 but btrfs raid5/6 support is immature. Meanwhile NTFS doesn't even support checksumming, multiple block devices, copy on write, the performance on SSDs is garbage, etc etc.
The whole of the NT kernel was essentially a futurized implementation of VAX-VMS.
Both VMS and NT had the same manager, in the person of Dave Cutler. Microsoft hired a large team away from DEC to build NT (which became the subject of litigation from DEC).
I have read that NTFS shares common architecture with Files-11/ODS-2&5 (native VMS filesystems). Aspects were also lifted from OS/2.
ZFS was developed a decade after NTFS. Most UNIX was still on FFS when NTFS was born.
