As we tech enthusiasts endlessly obsess over CPU cores, GPU teraflops, RAM speeds and other sexy PC specs, it‘s easy to overlook one humbler yet equally critical component – storage drives!
While that snazzy NVMe SSD gets your Windows booting in seconds flat, it‘s actually humble HDDs and SSDs that shoulder the vital task of preserving our precious data and digital memories for decades to come.
In my almost 15 years of building gaming rigs and upgrading office workstations, few brands garner such universal praise for balancing performance, quality engineering and value as Western Digital (aka WD).
But open any PC parts store page and you‘ll likely get overwhelmed by the dozen variations of WD‘s drives portfolio spanning different form factors, interfaces, capacities and purposes.
Well don‘t fret my friend! In this guide I‘ll equip you to parse through the retail mess by decoding what each WD color variant actually represents. My goal is to help match you to your ideal drive without either overspending or leaving too much untapped potential.
Let‘s start with a quick flyby overview before diving into nitty gritty details…
