The Samsung 9100 Pro 4TB is the objective winner of this comparison, securing five out of seven total specification victories. Its most significant advantage over the competition is its storage capacity, which is 300% better than that of the Sabrent Rocket 4 Plus 1TB. While the latter holds a lead in one category, the former dominates the majority of the measured technical specifications, establishing it as the superior option for users prioritizing high-density data storage.

Users who require maximum space for large libraries or extensive file collections should choose the Samsung 9100 Pro 4TB to leverage its superior capacity. Conversely, the Sabrent Rocket 4 Plus 1TB is the better choice for budget-conscious buyers, as it offers a 79% advantage in MSRP. Selecting between these two drives depends entirely on whether your primary requirement is the expansive storage volume of the Samsung or the cost-efficiency provided by the Sabrent.
