Storage Technology Futures to 2015: Flash, Disk Drive, Holographic, and New Technology Road Maps and Applications RevealedProduct Type: Market Research ReportPublished by: IDC Published: June 2006 Product Code: R104-26972 Description
This IDC study compares and contrasts several nonvolatile memory technologies likely to be commercialized through 2015. The scope of the study includes magnetic, optical, semiconductor (cross-point array), and other types of future nonvolatile memory technologies. A primer for each nonvolatile memory technology within the scope of the study is provided, as are the pros and cons and obstacles to overcome for further scaling or successful commercialization of each technology. Roadmaps related to the timing for commercialization as well as projections for density and price per gigabyte are given, enabling the reader to compare between each of the storage technologies. The suitability for storage applications is considered as are the risks and benefits related to developing each of the storage technologies into successful commercial products. "To borrow a quote from Mark Twain: 'The reports of the hard disk drive's death have been greatly exaggerated,'" according to John Rydning, IDC's research manager for hard disk drives. "Mapping-out technology and usage roadmaps through 2015 reveal clear strengths for some storage technologies and potential battle grounds between others." Table of Contents
