WD Red Plus NAS WD120EFBX 256MB 12TB

The main distinction between the WD Red Plus WD120EFBX and the WD Red Plus WD120EFGX lies in their cache memory, which can impact performance, especially under heavy NAS workloads. The WD120EFGX model offers significantly more cache at 512MB compared to the 256MB found in the WD120EFBX drive. Both drives share core specifications critical for NAS environments, including a 12TB capacity, 7200 RPM speed, 3.5-inch form factor, and CMR recording technology. Furthermore, the WD120EFBX variant explicitly lists Error Recovery Control (ERC) as a feature, which is standard for high-end NAS drives but worth noting. For users prioritizing maximum buffer space for multitasking and demanding data handling within their network storage, the WD120EFGX with its larger cache is generally the superior choice.
