Manufacturer limited warranty: MZ-76E4T0 lists 5 years or TBW limit, whichever comes first; MZ-76Q4T0 lists 3 years or TBW limit, whichever comes first.

A larger cache, higher RPM or higher advertised sequential speed alone does not establish which drive is better for your workload.

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.
