The SK Hynix Platinum P51 2TB is the objective winner of this comparison, securing more individual specification victories than its competitor. While both drives share several identical performance metrics, the SK Hynix Platinum P51 2TB holds the most impactful advantage in sequential read speeds, which are 5% faster than those offered by the Lexar NM1090 Pro 2TB. This lead in raw data transfer capability establishes it as the superior option for users prioritizing peak read performance.

Users who frequently perform heavy write operations should choose the Lexar NM1090 Pro 2TB, as it provides a 100% advantage in endurance measured by total bytes written. Conversely, the SK Hynix Platinum P51 2TB is the better selection for those who prioritize faster sequential read speeds for their storage needs. Selecting between these two drives depends entirely on whether your specific workflow demands higher long-term write durability or a slight edge in read throughput.
