Interface: LNM790X008T-RNNNU lists PCIe 4.0 x4 / NVMe; MZ-VAP8T0 lists PCIe 5.0 x4 / NVMe 2.0.
Sequential read (up to MB/s): LNM790X008T-RNNNU lists 7000; MZ-VAP8T0 lists 14800.
Manufacturer limited warranty: LNM790X008T-RNNNU lists 5 years, subject to manufacturer terms; MZ-VAP8T0 lists 5 years or TBW limit, whichever comes first.
Sequential write (up to MB/s): LNM790X008T-RNNNU lists 6200; MZ-VAP8T0 lists 13400.

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.
