Both models are designed for desktop PCs and laptops, with the former coming as a value drive while the latter is designed for high-performance users. In addition to the WD Red NAS drives that the company previously admitted used SMR tech, WD is also shipping the tech into its 2.5"and 3.5" WD Blue and 2.5" WD Black lineups.
