I would imagine that a silo with multiple robots to place disks in many readers would be significantly better than tape in most ways, and would retain the low power advantage that tape enjoys over powered systems.
- welterde 13y agoThe time to read the complete tape might be longer than the time to read a blu-ray, but in terms of data rates modern tapes are still about a factor of 3 ahead of optical disks (160MB/s for Ultrium 6 vs 54MB/s for Blu-ray 12x).
