And here is Matt Ahrens, a ZFS co-founder saying the same ("there's nothing special about ZFS that requires/encourages the use of ECC RAM more so than any other filesystem"):

You are getting the same benefits using any filesystem while running with ECC.
Also the "myth" that wrong checksum calculations due to a bitflip will degrade a ZFS filesystem even faster is not valid.
There are some articles/newsgroups around explaining this in much more detail.
So: Using ZFS on non ECC is not inherently unsafer than other filesystems on non ECC.
