This is a myth.

This is true, but there is nothing that makes ZFS more dangerous
than another filesystem using non-ECC memory.

Generally a good idea.

Also a good idea.

Not stated strongly enough. Nobody should turn on dedup; people
who think they are experimenting should definitely not turn on
dedup; only people who have a completely sacrificial system and
a good knowledge of the data to be stored should consider dedup.

A Raspberry Pi with two disks *is* a NAS or an entry-level

It's not an awesome one, but it is certainly a cheap one and
useful for many purposes.
