The Samsung 9100 Pro 2TB is the objective winner of this comparison, securing more individual specification victories than its competitor. While the Lexar NM1090 Pro 2TB holds a significant advantage in endurance, offering 100% more total bytes written, the Samsung 9100 Pro 2TB maintains the overall lead by providing a 5% faster sequential read speed. These two drives offer distinct technical profiles that prioritize different operational strengths for potential users.

Choose the Samsung 9100 Pro 2TB if your primary requirement is maximizing sequential read performance for faster data access. Conversely, select the Lexar NM1090 Pro 2TB if you prioritize drive longevity and write-heavy workloads, as its superior endurance rating provides double the capacity for data writes over the lifespan of the hardware. Your decision should depend on whether you value raw read speed or long-term write durability for your specific storage needs.
