“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.

via SSDs have a ‘bleak’ future, researchers say – Computerworld.

Because SSDs have no moving parts, the time needed to write and read data is more than 100 times faster than that of hard disk drives that use read-write heads on actuator arms to find data on a spinning platter. But as NAND flash circuitry continues to shrink in size, the performance gap with hard disk drives will become more narrow, Grupp said.
