Why don't you hold all of your most precious data on that single S-ATA

Repeat experiment until you get up to something like google scale or the
other papers on failures in national labs in the US and then we can have
an informed discussion.
I'm not interested in discussing statistics with you. I'd rather discuss
fsync() and storage design issues.
ext3 is designed to work on single SATA disks, and it is not designed
to work on flash cards/degraded MD RAID5s, as Ted acknowledged.
You are simply incorrect, Ted did not say that ext3 does not work
with MD raid5.

I will let Ted clarify his text on his own, but the quoted text says "... have
potential...".
Why not ask Neil if he designed MD to not work properly with ext3?
