6.6/10verdict: good, not the best

The Lexar EQ790 is a PCIe Gen4x4 M.2 2280 drive for buyers who want a long warranty and high endurance ratings at the 2TB size. It suits desktop builds and homelab machines where airflow is decent or a heatsink is fitted. It is less suited to anyone who needs steady writes over very large transfers or a laptop with tight cooling.
