The Samsung 9100 Pro 8TB is the objective winner of this comparison, securing victory in four out of six measured specifications. Its most significant technical advantage is its sequential read speed, which outperforms the Samsung 870 EVO 2TB by 2543%. While the 870 EVO maintains a lead in MSRP, offering an 85% better value in that specific category, the 9100 Pro dominates the overall performance metrics across the board.

Users prioritizing raw speed and maximum storage capacity should choose the Samsung 9100 Pro 8TB for their high-performance requirements. Conversely, the Samsung 870 EVO 2TB is the superior choice for budget-conscious buyers who prioritize a lower MSRP over the extreme sequential read capabilities found in the higher-capacity model. Selecting between these two drives depends entirely on whether your primary goal is minimizing initial costs or maximizing data throughput and total storage volume.
