Endurance (TBW): CT4000T500SSD3 lists 2400; LNM790X004T-RNNNU lists 3000.
Sequential read (up to MB/s): CT4000T500SSD3 lists 7000; LNM790X004T-RNNNU lists 7400.
Manufacturer limited warranty: CT4000T500SSD3 lists 5 years or TBW limit, whichever comes first; LNM790X004T-RNNNU lists 5 years, subject to manufacturer terms.
Sequential write (up to MB/s): CT4000T500SSD3 lists 6900; LNM790X004T-RNNNU lists 6500.

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.
