HDD vs. SSD: The Battle for PC Storage Supremacy Continues
HDDs remain dominant but continue to slide; SSDs rack up major gains despite being a much smaller segment
Fang Zhang

Hard disk drives (HDD) for PCs will continue to face declining shipments this year while rival solid state drives (SSD) in computers exert pressure on their much bigger competitors with outsized triple-digit growth, according to an IHS iSuppli Storage market tracker report from information and analytics provider IHS.

PC HDD shipments in 2013 are forecast to decline to 436.9 million units, down 8 percent from 475.4 million last year. In comparison, SSD shipments in PCs will jump to 68.9 million units, up a resounding 122 percent from 31.1 million. The inimical decline vs. growth pattern between the two segments will continue next year and in the years ahead. From 2012 to 2017, the compound annual growth rate for PC HDD shipments will be in negative territory at
-2.9 percent, while that for PC SSDs comes out to an enviable 48.0 percent.
