Morningstar | Western Digital should continue to benefit from data proliferation; shares remain fairly valued.

Western Digital is the leader of the hard disk drive, or HDD, market. In recent years, the firm has sought to expand into solid-state drives, or SSDs, to broaden its data-storage offerings. SSDs are faster and more reliable than HDDs, and have been replacing HDDs across PCs and servers. Although HDDs continue to boast superior cost metrics and higher capacities, SSDs have been closing these gaps. In 2016, Western Digital acquired SanDisk, a major supplier of NAND flash memory used in SSDs. We view this move as shrewd, as it enabled Western Digital to vertically integrate with its own captive channel of NAND.Nevertheless, we see significant secular headwinds for Western Digital’s traditional HDD demand in PCs, stemming from an ongoing decline in annual PC unit sales and shift to SSDs. Also, the SSD space is considerably more competitive than the HDD market. Worth noting is that SanDisk was a no-moat business because of the highly cyclical nature of the memory space further hindered by high capital intensity. We remain skeptical that Western Digital will generate sustainable excess returns on invested capital, leading to our no-moat rating.HDDs remain prominent in data centers to fulfill the high-capacity storage needs of hyperscale cloud vendors and other enterprises generating large swaths of data. The acceleration of cloud deployments should benefit Western Digital, so long as it is able to keep driving capacities higher and costs lower. SSDs are also encroaching on HDD territory in servers, though, and thus will likely aid in Western Digital’s ability to curb overall HDD declines.Through the firm’s SanDisk acquisition, Western Digital has a joint venture (Flash Ventures) with Toshiba to collaborate in the development and manufacturing of NAND flash memory wafers. Due to financial troubles faced by Toshiba, it is in the process of selling its semiconductor unit to a consortium that does not include Western Digital. Although there have been some concerns regarding this arrangement, we do not anticipate any negative ramifications for Western Digital at this juncture.
