WDC vs NOK Comparison

Western Digital is a leading vertically integrated supplier of data storage solutions, spanning both hard disk drives and solid-state drives. In the HDD market it forms a practical duopoly with Seagate, and it is the largest global producer of NAND flash chips for SSDs in a joint venture with competitor Kioxia.

Nokia provides telecom equipment and services that are used to build wireless and fixed-line networks. It operates in four segments. The mobile networks segment, which sells equipment and services to telecom carriers to power public wireless networks, is the largest, followed closely by network infrastructure. Network infrastructure focuses on fixed networks, including infrastructure, solutions, and components for IP networks, optical networks, and submarine networks. Cloud and network services is a nascent segment catering to enterprises with as-a-service platforms. Nokia also has a sizable research division and patent business, where it licenses technology used by handset providers, consumer electronics firms, and other firms making electronic and Internet of Things products.
