Error rate per system is a better metric as you say - your original post said 'error rate per
system administrator' which was a bit confusing.
A better btrfs

If a major cost of disk errors is a system administrator having to replace a disk, restore from backup, recreate data, etc., then you care how many times a year the system administrator has to do that. Consolidating data from two systems onto one doubles your error rate per system, but doesn't mean you have to increase your RAID redundancy and such because the error rate per system administrator is still the same. On the other hand, piling a terabyte of movies onto the systems managed by a system administrator increases that error rate and might require some new method of dealing with the errors.
