The Crucial T705 4TB is the objective winner of this comparison, securing victories in five out of seven measured specifications. Its most impactful advantage is its storage capacity, which is 100% greater than that of its competitor. By offering double the space, this drive provides a significant hardware lead that outweighs the performance of the alternative in terms of total volume.

Users requiring maximum storage space for large libraries or extensive data sets should choose the Crucial T705 4TB for its superior capacity. Conversely, those prioritizing a lower MSRP should opt for the Samsung 990 Pro 2TB, which holds a 73% advantage in that specific category. Selecting between these two components depends entirely on whether your primary requirement is the expanded room provided by the former or the cost-efficiency offered by the latter.
