I wrote a long comparative article on filesystem design, but with a strong BSD spine running through it.

The piece covers FFS/FFS2, ZFS, BFS, NTFS, ext4 and APFS, with particular attention to:

- cylinder groups

- soft updates and crash consistency

- journaling vs CoW

- integrity models

- snapshots, clones and space sharing

- why APFS matters from an Apple/BSD lineage perspective

The APFS section is the destination, but I wanted the broader context first so the comparison would actually mean something.

Interested in where FreeBSD people think I was fair or unfair, especially on FFS/UFS and ZFS.

I wrote a long-form comparative piece on filesystem design, with ext4 as one of the central reference points but not the only one.

The article walks through FFS/FFS2, BFS, NTFS, ext4, ZFS and APFS, focusing on the design tradeoffs that actually matter in practice:

- journaling vs soft updates vs CoW

- snapshots and clones

- checksums and integrity models

- encryption as bolt-on vs built-in

- space sharing vs old partition thinking

It is not a benchmark post and not a distro-war piece. The point is architectural tradeoffs, and why some filesystems feel boring but dependable while others aim for stronger guarantees or tighter OS integration.

Curious to hear where Linux people disagree, especially on ext4 vs ZFS vs the APFS comparison.

I wrote a long post on filesystem design with one main goal: explain why APFS matters beyond “it’s the filesystem macOS uses”.

To get there, I compare APFS with FFS, BFS, NTFS, ext4 and ZFS, then look at:

- APFS containers and shared space

- copy-on-write

- snapshots and clones

- encryption by design

- crash consistency

- why APFS is tightly tied to Apple’s broader security model

The article is technical, but still high-level enough to be readable if you are curious about what sits underneath modern macOS.

I wrote a long-form comparative piece on filesystem design, but the real target is APFS and the role it plays in Apple’s platform security model.

The article walks through FFS/FFS2, BFS, NTFS, ext4 and ZFS first, then uses that background to explain why APFS is not just “Apple’s default filesystem”, but part of how modern macOS thinks about crash consistency, snapshots, encryption, space sharing and system integrity.

It is not a buyer’s guide and not a generic “top filesystems” post. The point is to look at the underlying design choices and why they matter.

I’ll follow up with the APFS/macOS hardening part.
