Researchers: SSDs have bleak future

While the density of SSDs grows and the cost per gigabyte shrinks, "everything else about them is poised to get worse," Grupp said.

"This makes the future of SSDs cloudy: While the growing capacity of SSDs and high IOP rates will make them attractive for many applications, the reduction in performance that is necessary to increase capacity while keeping costs in check may make it difficult for SSDs to scale as a viable technology for some applications," Grupp, lead author of the study, wrote in a research paper.
