I found my code, and it looks like I was using 128 MB. This was around 2005.

A study done [1] at Google based on 2.5 years of observations of their servers, first published in 2009, found error rates from 25000-70000 errors per billion device hours per Mb. That would put the time Google was doing the study in the right era for when I did my test.

Based on that I would expect to see about 1 error per 40 hours in a 128 MB buffer if the buffer was on a Google server. I suppose that supports the theory that the data center environment is a lot more error prone than my home environment was.
