smartctl -x reports the wear on decent ones (read: you shouldn't consider
any that doesn't have this feature). When it gets close to 0, or you see a
lot of errors, it's time to replace it.

Apparently so! The last time I was looking at buying a significant amount

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.

Hi,
I just setup a Dell PowerEdge T20 using Smart OS and it works just
fine. It start at 2199kr (not including VAT) so it is a cheap server
too. I went for the Xeon E3 processor which is a bit more expensive but
you might be ok with the cheaper options.
Here's the link

I have an N40L configured w/ 4 x 2 TB disks and 8 GB of ECC DRAM. The disks
have two partitions each. A small one for a 4 way mirrored root pool and a
large one for data using double parity RAIDZ. It's a bit of extra work to
configure, but works very nicely giving 100+ MB/s disk I/O. (179 MB
I have an N40l that I built up to 16 gb ecc memory, 4 3tb red wd drives, and a

with Linux. It runs OI very well too other than I have not got
