Abstract: “This paper describes trends in the storage technologies associated with Linear Tape Open (LTO) Tape cartridges, hard disk drives (HDD), and NAND Flash based storage devices including solid-state drives (SSD). This technology discussion centers on the relationship between cost/bit and bit density and, specifically on how the Moore’s Law perception that areal density doubling and cost/bit halving every two years is no longer being achieved for storage based components. This observation and a Moore’s Law Discussion are demonstrated with data from nine-year storage technology trends, assembled from publically available industry reporting sources.“
