The Lexar NM1090 Pro 2TB is the objective winner of this comparison, securing victories in five out of seven evaluated specifications. Its most significant advantage is its sequential read speed, which outperforms the alternative by 237 percent. This substantial lead in data transfer capability establishes it as the superior choice for users prioritizing raw performance and high-speed throughput in their storage solutions.

Users who require maximum speed for demanding tasks should select the Lexar NM1090 Pro 2TB to leverage its dominant sequential read performance. Conversely, the Western Digital WD Blue SN580 2TB is the appropriate choice for budget-conscious buyers, as it holds a 65 percent advantage in MSRP. Choosing between these two drives depends entirely on whether the user prioritizes the significant speed gains of the Lexar or the cost efficiency offered by the Western Digital.
