The Western Digital WD Black SN8100 4TB is the objective winner of this comparison, securing five out of seven total specifications. The most impactful advantage for this drive is its sequential write performance, which is 175% better than the alternative. While the Samsung 980 Pro 2TB maintains a 64% advantage in MSRP, the superior write capabilities and higher capacity of the Western Digital drive establish it as the more capable hardware option across the majority of measured categories.

Users who prioritize maximum storage capacity and high-speed sequential write operations should choose the Western Digital WD Black SN8100 4TB for their system. Conversely, the Samsung 980 Pro 2TB is the appropriate selection for buyers who are primarily focused on the MSRP advantage. By weighing the importance of write speed and total capacity against the cost-efficiency of the smaller drive, users can align their purchase with their specific performance or budgetary requirements.
