Alan Somers - BFFFS: a novel SMR-native file system written in Rust

SMR (shingled magnetic recording) hard drives have higher densities than traditional hard drives, but impose a purely-sequential write order constraint on their users. This is an imposing barrier to adapting existing file systems; few can use SMR hard drives. This talk presents BFFFS, a novel file system built from scratch to be SMR-compatible. It's a copy-on-write file system, with all the usual features like snapshots and transactional integrity. And it's written in Rust.

Recorded at Colorado Gold Rust 2019 in Denver, Colorado.
