Independent failures?
The statement "probability of data loss to 1 in over 2 million years when properly monitored and maintained" sounds rather fishy to me. What are the chances that they've taken "failure rate for a single disk" and just multiplied that up N times, assuming that all failures are independent? Even if you declare lightning strikes and earthquakes as outside the calculation, disks that are hosted in the same environment, and which were probably all made in the same production run, don't have independent failure rates.
