The TerraMaster F4-425 Plus is a four-bay hybrid NAS that combines four SATA bays with three M.2 NVMe slots. TerraMaster's official specification identifies an Intel N150 quad-core processor, 16GB of DDR5 memory and support for up to 32GB. Dual 5GbE network ports are a major differentiator in this price and bay class, especially for multi-user transfers and creative workloads. TerraMaster also specifies hardware video transcoding and direct support for media-server applications including Plex, Emby and Jellyfin. TOS 7 provides TRAID and standard RAID options, snapshots, Docker tooling and VirtualBox support. Because TerraMaster's marketing page contains some inconsistent CPU wording, DiskBarn should retain the official specification sheet as the controlling source for the N150 configuration.
