Choose 870 EVO 500GB if dram cache matters more to you.
AI Versus Verdict
The Silicon Power UD90 1TB is the objective winner of this comparison, securing victories in four out of six evaluated specifications. Its most significant advantage is a 757% higher sequential read speed compared to the alternative. While the Samsung 870 EVO 500GB maintains a notable lead in its inclusion of a DRAM cache, which is 100% better than the competition, the overall performance profile favors the Silicon Power UD90 1TB across the majority of measured categories.
Users prioritizing raw data transfer speeds should select the Silicon Power UD90 1TB for its superior sequential read capabilities. Conversely, the Samsung 870 EVO 500GB remains the appropriate choice for those who specifically require the benefits of a DRAM cache for their storage operations. Choosing between these two drives depends on whether your primary workflow demands the high-speed throughput of the Silicon Power model or the specific architectural advantage provided by the Samsung drive.
