That depends on definitions.

E.g. Aircraft structures are subjected to many short 'test flights' in
the lab to pressurise and depressusrise tham way faster than they are in
service so that they *can* give lifetimes in years *of normal use* by
subjecting then to months *of abnormal use*.

coimpared with standrad disks and extrapoloated...uing real disk failure
rates as the initial value
