[OpenIndiana-discuss] Low low end server

[alka]

For me my data at home are as valuable like my data at work
and undetected RAM problems are the most probable way to loose 
or change data without a warning from ZFS. 

But ZFS without ECC  can detect much more problems without ECC
than filesystems without integrated checksums but with ECC.

Main argument for ECC is the minimal premium.
Why do you want to avoid ECC?
