On 6 april, FreeBSD developer and comitter Pawel Jakub Dawidek made a lot of people happy by announcing that the Zettabyte File System (ZFS) has been imported into the FreeBSD development tree. This means the brand new filesystem developed by Sun Microsystems is now part of FreeBSD-CURRENT and will be incorporated in the next major release version, FreeBSD 7.0.
ZFS is a modern filesystem that adds many long awaited features to the realm of filesystems, such as a pool-based storage architecture, software RAID systems (levels 0,1,5,6,10), per-directory compression, integrity checksums, snapshots and many more. The 128-bit filesystem was already available in Solaris 10, the UNIX-release of Sun Microsystems. It has been released under an Open Source license allowing FreeBSD to port it to their own source tree.
Linux users will probably have to wait longer for ZFS, since because of the restrictive GPL-license importing ZFS is not an easy task. The FUSE-project is formed to import ZFS as a userland-feature. This has several disadvantages when compared to an in-kernel implementation, performance being an obvious issue.
Users of FreeBSD are reminded that ZFS is currently an experimental feature and bugs are still being fixed. But the road to a stable ZFS is a promising one.

So when ZFS is ported to Linux, FreeBSD's ZFS is still better?

Yes, because FreeBSD's ZFS will be in kernel space and Linux' ZFS will be in user-space (FUSE, File system in User SpacE), resulting in severely degraded performance.

ZFS will change lots of things in FS world, but right now its not bootable which means it can never be a 'default' FS. This will hinder its market penetration im afraid.
Though adding ZFS boot support *is* possible.

ZFS is slow last time i tested it. Features were nice though.
execution time: 58 msec, queries: 13
