[OpenIndiana-discuss] Low low end server

[Robbie Crash]

For a home job, is there really any reason to use ECC RAM?

Like, real world I mean. Not "Realistically all servers should use ECC RAM
to protect the sanctity of the harmonious existence of all data from
interloping cosmic radiation" or whatever, but real world justification?

With ZFS checksumming, isn't the likelihood of data corruption due to
flipped RAM bits small enough to offset the cost difference for /home/ use?
ZFS was built to handle RAM errors, wasn't it?

I'm running an i3 21020T, 32GB of normal non-ECC RAM, 4WD Green 2TBs and 4
WD Black 1TBs each in RAIDZ, with a pool that I've filled and emptied twice
in the last few years, and aside from when a hdd froze last winter I've had
zero reported errors in my data and the only performance bottleneck is my
network speed.
