There's no FUD here. The problem is that you didn't say that you've
designed this for only a few nines.

Right. 6 or 7.

If you delete fsck from your
rationale, simply saying that you rely on UPS to give you time to flush
buffers, you have a much better story. Certainly, once you've flushed
buffers and degraded to write-through mode, you're obviously as reliable
as ext2/3.

Fsck was never a part of my rationale. Only reliability of components
was and is. Then people jumped in saying Linux is too unreliable to
use in a, hmm, storage system. Or transaction processing system. Or
whatever.

Balderdash, I say.

Your idea seems predicated on throwing large amounts of RAM at the
problem. What I want to know is this: Is it really 25 times faster than
ext3 with an equally huge buffer cache?

Yes.
