A Mh is, lessee, 100 years? So one failure per hundred systems per
year? Or if it is truly due to wear, perhaps it is zero failures per
hundred systems for 50 years, then an increasing failure rate out to
If it is wear, however, lifetimes may depend on usage, and using it as a
root fs and/or home directory may significantly shorten lifetime.
