The Samsung 990 EVO Plus 2TB wins in 4 out of 6 comparable specs. Its biggest advantage is Sequential Read (1195% better).
870 EVO 500GB wins in 2 specs (DRAM Cache: 100% better).
Recommendation
Choose 990 EVO Plus 2TB if you want the best overall performance — especially sequential read.
Choose 870 EVO 500GB if dram cache matters more to you.
AI Versus Verdict
The Samsung 990 EVO Plus 2TB is the objective winner of this comparison, securing victories in four out of six evaluated specifications. Its most impactful advantage is a sequential read speed that is 1195% better than the alternative. While the Samsung 870 EVO 500GB maintains a significant lead in memory architecture with a DRAM cache that is 100% better, it cannot overcome the substantial performance gap in data transfer rates established by the winning drive.
Users prioritizing raw data throughput and maximum storage capacity should choose the Samsung 990 EVO Plus 2TB for their system. Conversely, the Samsung 870 EVO 500GB remains the appropriate selection for those who specifically require the benefits of a DRAM cache for their storage operations. Selecting between these two drives depends entirely on whether your primary requirement is the superior sequential read capability of the newer model or the specific memory architecture provided by the older unit.
