A Conversation with Chris Mason on BTRfs
Chris: Linux has grown a rich infrastructure for filesystems, making it very easy to experiment and innovate with different storage technologies. So, it isn’t surprising that many different filesystem projects have found their way into the kernel. One of the reasons we are able to sustain these projects is because Linux is used with so many different workloads and types of storage.

The Ext4 Linux file system
Ext3, the default Linux file system for many years, is definitely starting to show its age. Modern mass storage devices are approaching its limits and block-based data management is no longer adequate for modern file sizes. High time for an update!

Testing Out The SSD Mode In Btrfs
One month ago we provided benchmarks of the Btrfs file-system and found that while it contained many features to make it a next-generation Linux file-system, its disk performance was rather displeasing. We had found the EXT4 file-system ran faster in a number of the tests and even EXT3 and XFS had their own advantages. Besides offering features like snapshots and online defragmentation, Btrfs has a mode that is optimized for solid-state drives. Will the Btrfs SSD mode cause this new Oracle-sponsored file-system to be the best for non-rotating media? We have benchmarks in this article, but the results may not be what one would expect. [...] The Btrfs SSD mode ended out our last test still being slower than not using the SSD mount option.

Btrfs Benchmarks: Btrfs Is Not Yet The Performance King
With the release this week of Fedora 11 Preview, which incorporates install-time support for the Btrfs file-system into Red Hat's Anaconda installer, we have now delivered our first set of benchmark results for this next-generation Linux file-system. Through a horde of disk tests we have looked at the Btrfs file-system performance and compared it to that of EXT3, EXT4, and XFS. While Btrfs does perform well in some areas, it is not yet the performance king for Linux file-systems. As our results show, in some tests it even has a hard time competing with the incremental EXT4 file-system.

Linux Don't Need No Stinkin' ZFS: BTRFS Intro & Benchmarks
ZFS may be locked into the Solaris operating system but “Butter FS” is on the horizon and it’s boasting more features and better performance.

Btrfs Merged Into Mainline Linux Kernel
Btrfs, the next-generation Linux file-system conceived by Oracle and designed to compete with some of the features found in Sun's ZFS file-system, has just been merged for the Linux 2.6.29 kernel.

The Evolution Of An GNU Project
First lets be honest GnoMenu is a fork of another project the "Gnome Vista Start Menu" by Chris Hughes. Most hard core Linux users looked at the menu Chris did as a cheap Vista look alike. In some ways it was but Chris also stated that other menu designs were possible yet no one really bothered to pay attention. Well almost nobody. Enter Helder Fraga who took Chris' work and forked it into GnoMenu.

Appeal for BtrFS Inclusion in Kernel
