The Lexar NM1090 Pro 2TB is the objective winner of this comparison, securing a lead in four out of seven evaluated specifications. Its most significant advantage is its endurance, as the drive offers a 100% improvement in total bytes written compared to the alternative. This superior durability rating makes it the more robust option for long-term data storage and heavy write operations, effectively doubling the lifespan capacity provided by the Samsung 990 Pro 2TB.

Users who prioritize hardware longevity and frequent data writing should choose the Lexar NM1090 Pro 2TB for its substantial endurance advantage. Conversely, the Samsung 990 Pro 2TB is the better selection for budget-conscious buyers, as it holds a 35% advantage in MSRP. Selecting between these two drives depends entirely on whether the user values the doubled endurance capacity of the Lexar model or the lower initial cost offered by the Samsung drive.
