This does not appear to be a consumer-oriented format like CDs and DVDs, but rather a niche product. Meaning that it will probably be not cheap. How is it supposed to be competitive with tape? 1TB is not that much.
- jackgavigan 13y agoTape is less reliable than optical disks.
- stonith 13y agoIt's also so slow to retrieve the content that as a DR strategy it's not very good, since you could be waiting months to recover all your data. 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).
- kalleboo 13y agoI wonder what happened to the idea of multiple optical read heads. When CD-ROM drives were trying to maintain 52x read rates, I think Pioneer or someone made a drive that read at twice the rate using 2 separate optical assemblies.

- sp332 13y agoBD-R's are metal-based, not dye-based. They may be more fragile than DVDs, but they are very light- and heat-resistant.

- aw3c2 13y agoThanks! I was more wondering about the lifespan of a resting medium though.
- sp332 13y agoYeah, I'm having trouble finding numbers for tape (my google-fu is weak).
