New optical technology will allow storage of one Petabyte on a single DVD.

New technology that will revolutionize data storage has been developed. This allows the storage of one Petabyte or 1,000 Terabytes of data on one DVD disk. This is far more than the 50 GiB that a standard dual-layer Blueray disk can fit. This would mean that you could put an 8K resolution movie on a single DVD and have video storage quality far above the current standard. This is good for anyone that wants to backup their entire RAID array onto a single disk. I hope that this technology results in higher quality games for consoles though. There must be a reason that the PS3 has far inferior graphical quality than a PC with moderately priced hardware. But the ability to store this much data on a DVD will result in burn times being very long indeed. But backing up your computer is very important. This can only be a good thing, in terms of storing massive amounts of user data. We can only hope that the reliability of the disks is up to scratch. it would suck if you burned all of your data to a disk and then could not recover it due to a scratch on the disk. Archival quality disks are good to use though. Just make sure that you store them somewhere safe to protect your sensitive data. How much will we be storing in the future? One Zettabyte on a disk? That would be incredible? Although there would be a limit to the size of individual pits on the disk that would necessitate the invention of another storage medium altogether. Maybe we will use a block of crystal and store data holographically. We possibly could store thousands of Petabytes that way. The future is looking very bright for data archival.
