Are you inferring that NICs are as prone to failure as power supplies?
 There must be some extenuating circumstances as to what you've
experienced in the past year.  Saying NICs are as prone to failure as
power supplies would be hard to back up by sampling MTBF data, even
with power supply companies grossly inflating their numbers.

One could limit sample data to their experience... In your case 100%
of NICs have failed out of the 2 sampled, in less than 10 years!

Sounds like bonding is a better solution for your scenario.
