Although disc-based storage is not as widely used as it once was for digital evidence archiving, it remains a viable solution when properly implemented and managed. In fact, many of the world’s largest technology companies are using and/or exploring disc-based storage systems for long-term offline storage of petabytes of customer data (e.g. Facebook uses 10,000 Blu-ray discs to store 'cold' data). They do so, however, in a managed environment with a thorough understanding of the medium’s strengths and limitations.

Many in law enforcement use write-once disc-based media for MASTER evidence storage, as it continues to be recommended via various industry best practice documents. Unfortunately, not everyone involved in the evidence chain understands the limitations and best practices as they relate to the care and handling of disc-based media. Adhesive labels, permanent markers, and ballpoint pens have destroyed more evidence than I care to even think about.

1080 for sure, that's in the name.  They're all the same thing folks, and I'll be darned if I can find any formal video specification referencing any of them, so they share that too.  Is it all just marketing BS?  No, but surely the confusion has been leveraged by some DCCTV manufacturers, resellers, and the like to their benefit.
