Linux Magazine has a pretty nice little article about Btrfs, a new enterprise level file system developed by Oracle which recently entered the Linux kernel.
The article has a comparison with ZFS, Sun’s (well, now Oracle’s) file system which is not Linux compatible, as well as some benchmarks. It’s an interesting, short read. The Btrfs file system does look very, very promising.
Don’t forget this is still pre-alpha (though it’s still yet to eat my data on my laptop’s SSD drive) !
