Or Btrfs. It may not be ready for production now, but it could become a
serious alternative to ZFS in one year's time or so. (I have been using

I will much sooner pay for sol11 instead of use btrfs.  Stability&  speed&  
maturity greatly outweigh a few hundred dollars a year, if you run your business on it.

Well, a typical conversation about speed and stability usually boils down to 
this:

A: I've heard that XYZ is unstable and slow.
B: Are you sure? Have you tested XYZ? What are your benchmark results? Have you 
had any issues?
A: No. I *have* *not* *tested* XYZ. I think XYZ is so unstable and slow that 
it's not worth testing.

It is true that the userspace utilities for Btrfs are immature. But nobody says 
Btrfs is ready for business deployments *right* *now*. I merely said it could 
become a serious alternative to ZFS in one year's time.

As far as stability is concerned, I haven't had any issues so far. Neither with 
ZFS, nor with Btrfs.

As far as performance is concerned, some people probably own a crystal ball. This explains their 
ability to guess whether Btrfs will outperform ZFS or not, once the first "stable" 
release of Btrfs is out. Unfortunately, I'm not a prophet. ;-) So I'll have to make a decision 
based on benchmarks and thorough testing on some of my machines, as soon as the first 
"stable" release of Btrfs is out.
