Nothing Last Forever But Blu-Ray Discs May Last 100 Years

by Aubra Salt - The Oregon Herald Friday December 11, 2015    6:47 PM
Flash (USB) Drives will last a few months or a year or so, or less. They begin to breakdown quickly so using them for backup is not at all wise.

Standard hard drives, IDE, SATA, last longer but they also begin to break down in 4 to 7 years.

The new Solid State drives are great but they don't last too long, perhaps less than SATA drives.

DVD storage may last a few years if you're lucky. TAPE backup, as we use to use is a good choice but it can be clumsy and awkward to store and retrieve.

This is sad news for Hollywood film producers who want to safe their digital films costing a few hundred million dollars each. The won't late forever. Yes, then can be backuped and repeatedly onto new media and kept in cold storage, but who has that kind of money?

Blu-Ray: Advantages and Disadvantages

Blu-ray is an optical disc format that was developed to enable recording, playback, and rewriting of high-definition video. Its main uses are for storing high-definition video, PlayStation 3 video games, and other data. Advantages and disadvantages of Blu-ray are listed below. Please comment based on your experience with Blu-ray.

Advantages:
  • Large Storage Capacity
  • Digital Rights Management (DRM)- like Itunes Blu-ray will only let a disc be copied a certain number of times to help prevent piracy
  • Universality, meaning major corporations already are or are planning to support Blu-ray compatability in recent and future technology
  • Inclusion in gaming consoles (one device multiple benefits)
  • Backwards compatability
Disadvantages:
  • Very Expensive Technology
  • High Definition capacity is not a substantial amount even though storage space is great
  • There is a slim selection of enticing movies titles that are blu-ray, should increase in the future but currently the daunting price for blu-ray without a large selection of films leaves the technology at a disadvantage
  • Due to increasing popularity of High Definition DVD players, blu-ray may be nullified because consumers will settle for the less expensive competitor
  • Not only is the technology expensive but Blu-ray discs have a higher price tag as well

From Wikipedia.com
Another option for archival backup is LTO cartridges from Quantum Corp. The process uses inexpensive media; ubiquitous hardware but they are expensive and most use SCSI drives.


Sony's Archival Disc are designed to hold 300 gigabytes of data in their first release, then a second version of the discs will hold up to 500 gigabytes, and eventually a third version of the discs will be able to store up to one terabyte of data, based on the roadmap plans of both companies.

The Archival Disc standard jointly developed by Sony and Panasonic will utilise signal processing technologies such as narrow track pitch crosstalk cancellation, high linear density inter-symbol interference cancellation and multi-level recording. The disc structure will feature dual sides, with three layers on each side, and a land and groove format. The track pitch is 0.225 µm, the data bit length is 79.5 nm, and the standard will utilise the method of Reed-Solomon Code error detection.

Sony expects the new standard to see usage in the film industry (such as storage of 4K resolution audiovisual data), archival services, and cloud data centres handling big data. The disc format is not intended as a consumer storage medium as of 2014, but is intended by the two companies as a solution for professional-level data archival. In order to reach a larger capacity whilst ensuring higher playback signal quality, the standard will employ crosstalk cancellation and partial response maximum likelihood (PRML) signal processing.[1] Both companies will market the optical format under their respective brands.
