The Samsung 9100 Pro 4TB is the objective winner of this comparison, securing victory in four out of six measured specifications. Its most significant advantage is its sequential read speed, which outperforms the Samsung 870 EVO 1TB by 2543%. While the latter remains competitive in terms of its MSRP, which is 85% better than the former, the superior performance capabilities of the 9100 Pro 4TB establish it as the more powerful storage solution overall.

Users prioritizing raw speed and high-capacity storage should choose the Samsung 9100 Pro 4TB to take advantage of its massive sequential read gains. Conversely, the Samsung 870 EVO 1TB is the better choice for budget-conscious buyers who value a significantly lower MSRP over the high-performance metrics found in the alternative. Selecting between these two depends entirely on whether your primary requirement is maximizing data throughput or minimizing your initial financial investment.
