The Samsung 870 EVO 2TB and the Samsung 990 EVO Plus 2TB result in an objective tie across the evaluated specifications. While both drives offer distinct technical strengths, the most impactful advantage for the former is its DRAM cache, which is 100% better than the alternative. Conversely, the latter provides a significant performance lead in sequential read speeds, which are 1195% better than those found on the 870 EVO.

Users who prioritize the presence of a DRAM cache should select the Samsung 870 EVO 2TB for their storage needs. Alternatively, those who require the highest possible sequential read speeds should choose the Samsung 990 EVO Plus 2TB. Each drive serves a different functional priority, so the decision depends entirely on whether your specific workload benefits more from the cache architecture or the superior sequential read capabilities provided by these components.
