New BD-DSD – Up to 200GB on a single disc
The BDA finalizes new specifications for optical storage media for professional use and data centers in the world: up to 200 GB on a dual-layer disc. The Blu-ray Disc Association has announced the completion of the new specifications Blu-ray Disc Double Sided Disc (BD-DSD) which allows you to record up to 200GB of information on Blu-Ray double-sided for use or professional use.
The specifications have been developed with the intention of creating a storage media that works with large systems for the management of large volumes (petabytes) of data and provides reliable and cheaper storage systems or tape based on a hard disk present in the data center.
Kei Yamashita, President of DSD Task Force of the Blu-ray Disc Association, commented: ” With the explosion of social media services, the shift towards cloud computing services and the digitization of our working lives and private institutional requirements for the storage of information is simply overwhelming.
Specific New BD-DSD can offer a very cost-effective and reliable way to meet these needs, while offering manufacturers to BD-DSD’s ability to create solutions that can reduce the environmental impact data center. ”
Reliability, first of all for the absence of physical contact between the support and the head of read/write during the operations, which is the case with both the tape media both with the hard disk. But the advantages are even more: according to a series of evaluations conducted on a single-sided disc, the operating costs for a 100 terabyte storage class could be significantly reduced by using the new BD-DSD compared to current solutions in the market thanks to the reduction of energy consumption is closely operating both those for cooling, with a consequent lowering of the carbon dioxide emissions.
BD-DSD will be mostly implemented in cartridges of tens or hundreds of discs, allowing data centers to use more cartridges to create systems capable of managing petabytes of data in a single array. The cartridges can be placed in operation by a robotic arm and once mounted the access time of the disc are similar to those of a storage system based to due hard disk and considerably lower than those of a tape system.
