The Samsung 870 EVO 1TB is the objective winner of this comparison, securing more category victories than its counterpart. Its most significant advantage is its capacity, which is 100% better than the smaller model. This doubling of storage space provides a substantial benefit for users who need to house larger libraries of files or applications on a single drive, making it the superior choice for those prioritizing maximum data volume.

The Samsung 870 EVO 500GB is the better option for budget-conscious buyers, as it holds a 43% advantage in MSRP. Users who require a reliable drive but have a lower total storage requirement should select this model to take advantage of the lower cost. Conversely, those who need the expanded capacity should choose the 1TB version to benefit from the increased space, as it remains the more capable drive overall.
