Solid state drives (SSDs) are digital storage devices; they are emerging as preferred devices over hard disk drives (HDDs) and gaining traction in the market. Made from semiconductors, SSDs contain microchip-based flash memory and have no moving parts, unlike HDDs. The global solid state drive market is classified on the basis of end-users into enterprise SSDs and client SSDs segments. In 2014, the client SSDs segment dominated the global solid state drive market in terms of revenue. The growth in this segment is mainly driven by demand from OEMs across North America and Asia Pacific. However, the enterprise SSD market is gaining traction due to growing demand from data center applications. On the basis of capacity, the solid state drive market is segmented as 80 GB and below, 81 GB to 320 GB, 321 GB to 500 GB, 501 GB to 1 TB, and 1 TB and above. In 2014, solid state drives with capacities of 80 GB and below led the global solid state drive market in terms of revenue. SSDs in ultra-thin mobile devices with capacities below 80 GB are boosting the growth of this segment. On the basis of interface, solid state drive market is segmented as SATA, SAS, and PCI-E. In 2014, SATA SSDs accounted for a major share—72.4%—of the global solid state drive market's revenue, and 80.0% of the global SSD volume. The older PCs support only the SATA interface for upgrading to SSDs, which is expected to increase the demand of this segment over the forecast period as well. However, enterprises will drive the revenue of PCI-E and SAS SSDs, making them the fastest-growing and largest-revenue-contributing segments, respectively, in 2022.
