Infinite Loop: A ZFS developer’s analysis of the good and bad in Apple’s new APFS file system

Two hours or so of WWDC keynoting and Tim Cook didn’t mention a new file system once? (credit: Andrew Cunningham)

This article was originally published on Adam Leventhal’s blog in multiple parts.

Apple announced a new file system that will make its way into all of its OS variants (macOS, tvOS, iOS, watchOS) in the coming years. Media coverage to this point has been mostly breathless elongations of Apple’s developer documentation. With a dearth of detail I decided to attend the presentation and Q&A with the APFS team at WWDC. Dominic Giampaolo and Eric Tamura, two members of the APFS team, gave an overview to a packed room; along with other members of the team, they patiently answered questions later in the day. With those data points and some first-hand usage I wanted to provide an overview and analysis both as a user of Apple-ecosystem products and as a long-time operating system and file system developer.

The overview is divided into several sections. I’d encourage you to jump around to topics of interest or skip right to the conclusion (or to the tweet summary). Highest praise goes to encryption; ire to data integrity.
