Storing even 5 TB of data onto bluray disks requires 100 disks of 50 GB dual layer capacity. That's a lot of disks.

- webmobdev 6y agoYeah. And that too if you are willing to ignore the really slow speed to write them all!
- Karunamon 6y agoIf you're doing archival storage, does the write speed really matter? If you have enough volume of incoming data where the write speed does matter, you've already eliminated most archival storage methods anyways.
- webmobdev 6y agoTrue. But slow transfer speed is still a negative when we are comparing it to other archival methods (in this case, the tape drives). And that is why the demand for tape drives for consumers.
- Karunamon 6y agoI'm having a very difficult time understanding why they are a negative at all for most use cases. It's not like running a backup monopolizes the machine you're running it on. Again, tapes are for archival storage. Not nearline, not live, archival. As in, you write the data and likely don't come back to it for months to years.
- dsego 6y agoThere might be a benefit to it. If 1 disc corrupts you only loose 50GB. If your hard drive fails, you loose all 5TB at once.
