Ok, after converting to MTBF the numbers make more sense: An AFR of 0.9% means a MTBF of 968947 hours (111 years). An AFR of 3.2% means a MTBF of 269346 hours (31 years).

I guess an MTBF of 31 years is plenty for your needs. Thanks again for sharing the data.

I think the failure rate will go up in old age. I just don't see those drives still working in 100 years.
