While I agree with Brent, I think this is something that should be stressed in 
the ZFS documentation.  Those of us with long term experience of ZFS know that 
it's really designed to work with hardware meeting quite specific requirements.

Unfortunately, that isn't documented anywhere, and more and more people are 
being bitten by quite severe dataloss by virtue of the fact that ZFS is far 
less forgiving than other filesystems when data hasn't been properly written to 
disk.

As far as I can see, the ZFS Administrator Guide is sorely lacking in any 
warning that you are risking data loss if you run on consumer grade hardware.  
In fact, the requirements section states nothing more than:

"ZFS Hardware and Software Requirements and Recommendations

Make sure you review the following hardware and software requirements and 
recommendations before attempting to use the ZFS software:

    * A SPARCĀ® or x86 system that is running the or the Solaris 10 6/06 release 
or later release.
    * The minimum disk size is 128 Mbytes. The minimum amount of disk space 
required for a storage pool is approximately 64 Mbytes.
    * Currently, the minimum amount of memory recommended to install a Solaris 
system is 768 Mbytes. However, for good ZFS performance, at least one Gbyte or 
more of memory is recommended.
    * If you create a mirrored disk configuration, multiple controllers are 
recommended."
