Was doing a little checking of the smart values of my disks in my ZFS arrays , a have a 12TB iron wolf mirror array for backups and slow media where I don't need the fast IO , How I think ZFS works is it should read and write to both drives at the same time , but looking at the smart value I'm a little confused .
Why does two drives in a mirror have different "Hour on time" ? and why does one drive have twice the "head flying hours" ? .
