Compatibility and buying checks

Sequential speeds are manufacturer maxima, not measured game load times. Check your PCIe generation, M.2 dimensions and cooling clearance. The lower of the time or endurance limit normally governs a limited SSD warranty.
Compare new and renewed offers separately. The manufacturer specification does not guarantee the warranty or return policy of a marketplace seller.
