Anandtech reports that demand for hard drive storage continues to be strong, with Seagate, Toshiba and Western Digital shipping 240 exabytes worth of hard drives in the third quarter of 2019.
Market observers are attributing the significant rise in shipping HDD capacity to increasing shipments of enterprise-class nearline 14 TB, 15 TB, and 16 TB hard drives, which by now have been qualified by a substantial number of companies. For example, the average capacity of Seagate’s enterprise HDD (mission critical + nearline drives) was 6.3 TB in Q3 2019, up from 5.2 TB in the same period last year. By contrast, the average capacity of Seagate’s client hard drives was at 1.2 TB (unchanged from Q3 2018), as the bulk of such drives are intended for notebooks and their capacities range from 500 GB to 1 TB. In terms of units shipped, client and consumer electronics HDDs by far outsell enterprise and nearline drives, so, the average capacity of a Seagate HDD is 2.9 TB, up from 2.5 TB a year ago.
