The BeOS file system, an OS geek retrospective
By Thom Holwerda on 2018-07-06 19:09:38

It's a bit of a slow news week in technology this week due the US celebrating Independence Day this past 4 July, so Ars decided to repost this article about BFS, and I'm nothing if not a sucker for BeOS content, so here it goes.

The Be operating system file system, known simply as BFS, is the file system for the Haiku, BeOS, and SkyOS operating systems. When it was created in the late '90s as part of the ill-fated BeOS project, BFS's ahead-of-its-time feature set immediately struck the fancy OS geeks. That feature set includes:

  • A 64-bit address space
  • Use of journaling
  • Highly multithreaded reading
  • Support of database-like extended file attributes
  • Optimization for streaming file access

A dozen years later, the legendary BFS still merits exploration - so we're diving in today, starting with some filesystem basics and moving on to a discussion of the above features. We also chatted with two people intimately familiar with the OS: the person who developed BFS for Be and the developer behind the open-source version of BFS.

A good read.
