LNM790X002T-RNNNU vs MZ-77Q2T0
SSD head-to-head - specs, value and live price side by side.
Verdict
For a NAS cache or write-heavy pool, the LNM790X002T-RNNNU is the safer pick - the MZ-77Q2T0 uses QLC NAND, which wears out faster and slows badly under sustained writes (light, read-mostly use only).
