WD Blue SN5000 WDS200T4B0E 2TB

When comparing the WD Blue SN5000 and the WD Green SN350, the most significant distinction lies in their underlying technology, specifically the PCIe interface standard. The SN5000 leverages the newer PCIe Gen4 x4 interface, offering substantially higher potential performance compared to the SN350's PCIe Gen3 x4 connection. Both drives come in a similar 2TB capacity, making storage size a non-differentiating factor here, and both utilize the convenient M.2 Type 2280 form factor. Consequently, the SN5000 is clearly positioned as the superior, higher-speed option, best suited for users requiring faster load times and data transfer rates, while the SN350 serves as a more budget-conscious entry into NVMe performance.
