The Samsung 9100 Pro 4TB is the objective winner of this comparison, securing victories in five out of seven measured specifications. Its most significant advantage is its storage capacity, which is 300% greater than that of the alternative. While both drives offer distinct benefits, the Samsung 9100 Pro 4TB provides a substantial lead in total space, making it the superior choice for users prioritizing high-volume data storage over other considerations.

Users who require extensive room for large files or massive game libraries should choose the Samsung 9100 Pro 4TB for its superior capacity.
