UEFI came up with the "reliable" wording (as a more generic term ...
as Andrew said
it could cover differences in ECC modes, or some alternate memory
technology that
has lower error rates).

But I personally like "mirror" more ... it matches current
implementation. Of course
I'll look silly if some future system does something other than mirror.
