The TerraMaster F4-422 is a small desktop NAS that is touted as a high-speed NAS. The high-speed handle comes from the device being loaded with a quad-core 1.5GHz Intel Celeron J355 CPU, an onboard 10 Gigabit LAN port, and up to 8GB of memory supported. This hardware (combined with the proper drives in the proper configuration) can lead to speeds as high as 670MB/s. Faster speeds can translate to more use cases such as video editing or transferring large volumes of data.
