The Seagate FireCuda 540 2TB is the objective winner of this comparison, securing more individual specification victories than its competitor. While the Samsung 990 Pro 2TB with Heatsink holds a 15% advantage in MSRP, the Seagate FireCuda 540 2TB provides a significantly more robust storage solution. Its most impactful advantage is a 67% higher endurance rating, measured in total bytes written, which establishes it as the superior option for long-term reliability and heavy write workloads.

Users who prioritize maximum drive longevity and frequent data writing should choose the Seagate FireCuda 540 2TB for its superior endurance capabilities. Conversely, the Samsung 990 Pro 2TB with Heatsink is the better selection for budget-conscious buyers who want to capitalize on its 15% MSRP advantage. Selecting between these two drives depends entirely on whether your primary requirement is the extended durability of the Seagate model or the initial cost savings offered by the Samsung unit.
