As someone else said, it’s similar to btrfs. bcachefs has a lot of functional overlap with btrfs, which is great. There have also been a few benchmarks showing that bcachesfs is faster for some situations (cold-cache warming, IIRC). One of the big advantages over btrfs is that bcachefs’s RAID is more robust - several of btrfs’s RAID levels have been marked as experimental and prone to data loss, for years. There’s been improvement in btrfs RAID lately; the skeptic in me believes this is directly a result of pressure from bcachefs, which is in a position to become a favored fs in Linux.
