The Samsung 990 Pro 2TB is the objective winner of this comparison, securing five out of seven total specifications. The most impactful advantage offered by this drive is its sequential read speed, which outperforms the Samsung 970 EVO Plus 1TB by 113 percent. While the latter component holds a single victory in the category of MSRP, the former demonstrates a clear technical superiority across the majority of the measured performance metrics.

Users prioritizing raw speed and maximum throughput should select the Samsung 990 Pro 2TB to leverage its significant sequential read advantage. Conversely, the Samsung 970 EVO Plus 1TB is the logical choice for budget-conscious buyers who value the 59 percent better MSRP over the performance gains found in the higher-tier model. Choosing between these two drives depends entirely on whether your primary requirement is top-tier data transfer capability or a more accessible initial cost.
