CT4000P3PSSD8 vs CT4000T705SSD3
SSD head-to-head - specs, value and live price side by side.
Verdict
For a NAS cache or write-heavy pool, the CT4000T705SSD3 is the safer pick - the CT4000P3PSSD8 uses QLC NAND, which wears out faster and slows badly under sustained writes (light, read-mostly use only).
