The Samsung 9100 Pro 4TB is the objective winner, securing victories in four out of six measured categories. Its most significant advantage is its sequential read speed, which outperforms the Samsung 870 EVO 2TB by 2543%. While the Samsung 870 EVO 2TB maintains a lead in MSRP with a 73% better value, the Samsung 9100 Pro 4TB dominates in overall technical specifications, establishing itself as the superior hardware choice for performance-focused applications.

Users prioritizing raw speed and maximum storage capacity should select the Samsung 9100 Pro 4TB to leverage its massive sequential read advantage. Conversely, the Samsung 870 EVO 2TB is the appropriate choice for budget-conscious buyers who prioritize the 73% better MSRP over high-end performance metrics. Choosing between these two drives depends entirely on whether your primary requirement is the significant speed increase offered by the former or the cost efficiency provided by the latter.
