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.
