The Samsung 9100 Pro 4TB is the objective winner of this comparison, securing more total spec victories than its counterpart. While both drives share identical performance in two categories, the 4TB model provides the most significant advantage by offering 300% more capacity than the smaller version. This substantial increase in storage space makes it the superior choice for users requiring extensive room for files, games, or media libraries compared to the alternative.

The Samsung 9100 Pro 1TB is the ideal selection for budget-conscious users, as it holds a 67% advantage in MSRP. Those who do not require the massive storage footprint of the larger drive can benefit from this significant cost efficiency. Conversely, the 4TB model is the better investment for power users or professionals who prioritize maximum capacity and need the expanded storage space for demanding workloads that exceed the 1TB limit.
