TOP 10 Reasons For Selecting Blu-ray Archiving Technology

Optical disk storage, like all forms of digital storage has a very important role in establishing and maintaining the accuracy, reliability and trustworthiness of electronic records. The main reasons for choosing optical blu-ray technology are:

1. Best  TCO
The total cost of ownership of Blu-ray storage for archival purposes is less than half the cost for alternatives like Hard Disk and tape, thanks to low energy consumption and cooling costs and no need for data migration and constant data back-up. More info>>>

2. Compliance

  • Blu-ray media offers a true WORM recording medium which can’t be altered with software hacks or viruses. This is essential considering  today’s requirements for multi-year data retention periods and growing regulatory  compliancy requirements for unalterable,non-erasable storage capabilities. Optical technology meets these requirements as part of its standard
  • Unlike media such as magnetic tape, the WORM (Write Once Read Many) BD-R physically prevents overwriting.
  • With its long-term storage ability, the BD-R eliminates security risks because data migration is unnecessary.
  • BDs have a serial number and an ID (recorded in the Burst Cutting Area (BCA) ), making it easy to verify the authenticity of the media itself.(*Special application software is required for reading the BCA.)

3. Capacity
Blu-ray Disc format is easily extendable (future-proof) as it includes support for multi-layer discs. This allows the storage capacity to increase the current 100-128GB/disc capacity to 200GB in the near future simply by adding more layers to the discs.

4. Compatibility
Optical media has industry standard formats; ISO 9660 and UDF (Universal Disk Format) which are supported on every operating system including Windows, Linux, UNIX and MAC OS X. This avoids the direct need for additional client software as data can still be read in a standard drive in a standard PC, yielding complete vendor Independence.
The Blu-ray Disc™ is the de facto standard for large-capacity optical discs, and is supported by about 170 major corporations, assuring long-term readability.







5. Access
Blu-ray technology offers random access to any file on Blu-ray Discs. Unlike with Hard Disk  storage, media is not spinning and less subject to physical damage, viruses, etc.  Tape drives  provide sequential access  and recovery times are  slow as the tape needs to spool to find the file.

6. Removability
Off-line management of very old information is not possible with magnetic hard disks as they can’t be safely removed and stored long-term outside of the archive. Tape can be removed and stored off-line, however, tape needs periodic re-tensing to prevent tape adhering together and is like hard disk vulnerable to (electro) magnetic radiation. Blu-ray Discs can be safely removed and stored off-line, offering unlimited archive storage capacity.

7. Innovation
While maintaining all benefits of a standardized format, Blu-ray technology is available as  a best-of- breed hybrid solution technology for organizations. Combining the removability and longevity of Blu-ray with direct access and speed of hard disk yields easy to deploy and maintain appliance type solutions.

8. Cloud & Blu-ray
Cloud storage has some advantages, but many companies choose for a mixed model to implement a secure, physical archive in place which is less susceptible to outages, network bandwidth and privacy breaches.

9. Green Technology
Blu-ray technology offers a sustainable archiving technology.  Blu-ray media consume zero power when not being accessed, reducing power consumption, air conditioning needs and CO2 emission.  As there is no need for frequent data migrations, less waste products will be generated by having to replace devices.







10. Long-Term /Longevity

  • Due to its advanced media lifetime of 50+ years , standardized format  and removability, Blu-ray technology offers the possibility to build long-term infinite off-line media archives.
  • Compared to magnetic tape and HDD, it is less likely to be affected by humidity, temperature and light, and resists changes over time.
  • Unlike magnetic tape and HDDs, there is no contact between the optical pickup (OPU) and the disc, so it maintains excellent durability even after repeated reading and writing.
  • Panasonic Blu-ray™ discs have an archival life of 50 or 100 years, in contrast to an HDD’s 5 to 10-year and magnetic tape’s 15-20-year archival life. This allows data to be stored for longer periods of time.
