I presume the MTBF you are talking about is the manufacturer's spec in each
case. If so, remember that in one case (CDC) you are talking about a
number that is a theoretical calculation. On the other hand, the Eagle's
reputation for reliability derives from experience in the field, not
the manufacturer's MTBF spec, which may be much more conservative. For
reference, a year is 8766 hours. If you plan on running 24-hours a day,
a 10,000-hour MTBF is pretty poor.
