The Samsung 9100 Pro 1TB is the objective winner of this comparison, securing victories in four out of six measured categories. Its most significant advantage is its sequential read speed, which outperforms the Samsung 870 EVO 500GB by 2525%. While the 870 EVO 500GB maintains a lead in MSRP, offering a 75% better value in that specific metric, the 9100 Pro 1TB dominates the technical performance landscape across the majority of the evaluated specifications.

Users prioritizing raw performance and high-speed data access should select the Samsung 9100 Pro 1TB to leverage its massive sequential read advantage. Conversely, the Samsung 870 EVO 500GB is the logical choice for budget-conscious buyers who prioritize the 75% better MSRP over the performance gains offered by the alternative. Your decision should rest on whether your primary requirement is maximizing data transfer speeds or minimizing the initial cost of your storage solution.
