FWIW, I like ZFS a lot so far - I'm pretty thrilled with the wide array of options for handling data and how easy it is to access them (I started here
for info used in actual implementation, as opposed to just reading about it), and the performance is pretty impressive so far - for my applications, it doesn't look as performant as Linux filesystems so far, but it certainly doesn't look shabby. And the data protection features are definitely worth performing a little slower than "the fastest thing available".
I just really wish there was some chance of resolving the CDDL/GPL licensing incompaitibility issues in order to make ZFS available on the Linux side. I am a FreeBSD guy from way back, but I've been migrating more to Linux lately (Ubuntu specifically) in favor of better package management... and better disk performance.
