Hi everybody,
I am considering moving my data pool from a two disk (10krpm) mirror
layout to a three disk raidz-1. This is just a single user workstation
environment, where I mostly perform compile jobs. From past experiences
with raid5 I am a little bit reluctant to do so, as software raid5 has
from a two disk (10krpm) mirror layout to a three disk raidz-1.
wrights will be unnoticeably slower for raidz1 because of parity calculation
and latency of a third spindle. but reads will be 1/2 the speed
of the mirror because it can split the reads between two disks.
another way to say the
