Western Digital vs. Seagate Technologies: Which Computer Hardware Stock is a Better Buy?

Organizations’ continuing adoption of hybrid working models and an ongoing digital transformation have fostered rising demand for computer hardware to utilize advanced technologies. As a result, popular computer hardware stocks Western Digital (WDC) and Seagate (STX) should benefit from growing investor optimism about this space. But let’s find out which of these two stocks is a better buy now.

Western Digital Corporation (WDC) in San Jose, Calif., and Dublin, Ireland-based Seagate Technology Holdings plc (STX) are two prominent players in the computer hardware industry. WDC develops, manufactures, and sells data storage devices and solutions, mainly hard-disk drives (HDDs) and solid-state drives (SDDs), and serves original equipment manufacturers (OEMs), distributors, resellers, and retailers worldwide. In comparison, STX develops, produces, and distributes data storage products and electronic data storage solutions. It also provides storage subsystems and mass capacity-optimized private cloud storage solutions for enterprises, cloud service providers, and scale-out storage servers and OEMs.

Because remote working is expected to continue with the impact of the now rampant COVID-19 Delta variant, organizations are increasingly adopting hybrid working models as a long-term solution. So, the need for efficient computing devices should drive massive demand for computer hardware, especially hard disk drives (HDDs) and solid-state drives (SDDs). The continuing digital transformation is also driving the demand for computer hardware. In fact, the global computer hardware market is expected to grow at 6% CAGR to  $1.18 billion by 2025. Consequently, both WDC and STX should see soaring demand for their products in the coming months.

But while WDC's share price declined  9.2% over the past month, STX has declined only marginally. In terms of the past six months’ performance, STX is a clear winner with 33% gains versus WDC’s 23.5%. But, which of these stocks is a better pick now? Let’s find out. 

Latest Movements 

On June 22, 2021, WDC announced its second-generation UFS 3.1 storage solution for smartphones, named Western Digital iNAND MC EU551, that delivers high-performance storage for consumers while using ultra-high-resolution cameras, AR/VR, gaming, and 8K video and other applications. As networks continue to expand available bandwidth and offer lower latency to enable new user experiences, WDC’s iNAND solutions are expected to see good demand in the coming months.

WDC announced the availability of its new high-performance Ultrastar Edge server family on June 15. The product  brings computers closer to where data is generated for faster processing, lower latency, and real-time decision making, even when disconnected. Amid the growing adoption of 5G, IoT, and the cloud, the need for secure and easy transport, deployment, and data analysis at the edge, is likely to generate high demand in the coming months.

On June 23, 2021, STX launched its newest PC gaming SSD, the FireCuda 530, at its inaugural virtual gaming event, SG21. This new drive offers gamers the latest PCIe Gen4 NVMe SSD technology and the fastest performance from STX’s line of PC gaming storage products, thus bringing speed, endurance, and high capacity to the peak of PC performance. STX expects to witness good demand for this drive in the coming months.

On June 22, STX launched the new Exos CORVAULT high-density storage system, a uniquely intelligent category of mass-capacity storage designed to streamline data management and reduce human intervention for macro edge and data center environments. STX’s new VelosCT chip powers the system’s dual storage controllers, driving superior performance, while STX’s Advanced Distributed Autonomic Protection Technology (ADAPT) offers advanced data protection and fast rebuilds without sacrificing performance. As a result, STX expects to gain widespread recognition of this storage system across the industry.
