Advanced Storage Techniques Using Scalable Media

Data storage is still one of the major bottlenecks in today's post-production workflows. Improving the data-throughput by combining some disks in a certain RAID-configuration makes the system faster but more expensive. In contrast, scalable compression techniques can also be used to significantly increase the overall throughput of storage devices. This work gives an overview of the development of storage techniques especially designed for scalable media files such as JPEG 2000 and H.264 SVC. This paper introduces two techniques: (1) a data-relocation algorithm exploiting foreseeable access pattern to the media content. This technique, in combination with scalable media achieves an singnificant increase in I/O performance of HDDs by a factor of three and (2) a novel RAID configuration especially designed for scalable media allowing for guaranteed real-time performance of attached storage devices.
