How many passes will my Imation 4mm Data Cartridge media sustain?
The metal particle media used in Imation 4mm cartridges will last in excess of 1500 physical passes in a drive under optimum laboratory conditions. The complex motions of writing the directory, then data, then rewinding and updating the directory, all in start/stop mode actually accumulates six to twelve physical tape passes each time the tape is used for a backup, restore or verify operation. You can expect about 250 backup, restore or verify operations under optimum conditions.
