But if an individual disk fails in a disk array, sooner than later you
would want to purchase a new fitting disk, walk/drive to the location
of the disk array, replace the broken disk in the array and activate
the new disk. Is this correct?
Thanks

... of individual disks, which is quite different from failure of a disk
array (in case there is one).
