And what, exactly, was the point of the initial inane statement, "Anyone
who is serious about protecting their data buys a hardware RAID
controller. Software RAID is a hack." That was the statement I
addressed. You were the one who made wild, sweeping, unsupported claims
about the efficacy of an entire class of storage solution, not I.

I'm not "caught up with" such an architecture. The context of that
statement was a (short) list of reasons why SW raid might be better than
cheap HW raid, specifically a a reason why SW raid might be more
"serious" about protecting data in some situations than HW raid.

So your point had nothing to do with your derogatory statements about
the SW raid implementation?

I've used md raid as a matter of course on all sorts of machines for
years now. I've had far fewer problems with these than with the
drivers for the various cheap raid cards.
