- Spinup cycles
Spinup Cycles (also called CSS, "on/off cycles" or "power cycles") is a value that
harddisk manufacturers give for the average times a harddrive canspin up before it fails.Usually server harddisks are specified for less spinup cycles than desktop harddisks, because servers are only very rarely
rebooted . On the other hand server harddisks have much higherMTBF .
