Having been checksumming filesystem data during continuous replication for two years now on multiple machines, and having caught exactly zero blocks of bad data passed as good in that time,
If TUX3 is for small systems, Philipps is probably right. I don't know what "continuous replication" means or how much data he's talking about here, but I have a feeling that studies I've seen calling for file checksumming did maybe 10,000 times as much I/O as this.
