Ext3 and RAID: silent data killers?

I don't know what 'high end storage servers' you are talking about, the even the multi-million dollar arrays from EMC and IBM do not have the characteristics that you are claiming.
Now that you mention it, I do remember that earlier IBM Sharks had nonvolatile storage based on a battery. Current ones don't, though. The battery's only job is to allow the machine to dump critical memory contents to disk drives after a loss of external power. I think that's the trend, but I haven't kept up on what EMC, Hitachi, etc. are doing. IBM's other high end storage server, the former XIV Nextra, is the same.
