piece with a somewhat misleading title that provides a good summary of the argument we've been making since at least early 2011 that the Kryder rate, the rate of annual decrease in the cost per byte of storage, had slowed dramatically. As we have shown, this slowing has huge implications for the cost of long-term storage.
similar summary of Preeti Gupta et al's MASCOTS paper, An Economic Perspective of Disk vs. Flash Media in Archival Storage. This paper reports on some more sophisticated economic modelling that supports the argument of DAWN: a Durable Array of Wimpy Nodes. This 2011 technical report showed that, using a similar fabric to Carnegie-Mellon's 2009 FAWN: a Fast Array of Wimpy Nodes for long-term storage instead of computation, the
running costs would be low enough to overcome the much higher cost of
the flash media as compared to disk
