The Seagate Barracuda 2TB and the Western Digital WD Blue SA510 2TB reach an objective tie across the evaluated specifications. While both drives offer distinct technical benefits, the most impactful advantage for the Seagate Barracuda 2TB is its DRAM cache, which is 100% better than the alternative. Conversely, the Western Digital WD Blue SA510 2TB provides a significant performance lead in sequential read speeds, which are 195% better than those found on the Seagate drive.

Users prioritizing sustained data handling and cache-dependent tasks should select the Seagate Barracuda 2TB for its superior DRAM capacity. Those who require faster data retrieval and prioritize high sequential read speeds for their storage needs should choose the Western Digital WD Blue SA510 2TB. Both components offer competitive advantages, so the final decision depends entirely on whether your specific workload benefits more from the increased cache or the faster sequential read performance.
