ZFS - Training Video

ZFS is still not stable for production use (thats what i have read so far), i have played around a lot with it and i feel its indeed a file system for the future. I hope something similar would be available on other platforms as well. I know for sure that Mac OS would definitely have it in its next release. This ZFS CBT would be extremely useful for newbies:

I don't own the above links, so i am not sure when they will go dead.

After working with so many file systems over the years, i feel that there should be a universal file system for all storage devices. I am sure someone, somewhere is already working on this idea.
