TerraMaster F4-213 4-bay NAS Server

TerraMaster F4-213 4-bay NAS Server

The TerraMaster F4-213 is a 4-bay NAS server for centralised storage, backup and file sharing at home or in a small office. It features an 8-core Rockchip RK3576 processor, 4 GB LPDDR5 memory, a 2.5 GbE network port and the TOS 7 operating system with built-in AI features. The four SATA bays support 3.5-inch and 2.5-inch HDDs and 2.5-inch SSDs, with up to 128 TB of raw capacity. Other features include hardware-accelerated 4K video decoding, RAID support, remote file access and multi-layer data protection.

Processor and network connectivity

The 8-core Rockchip RK3576 processor is manufactured using an 8 nm process and handles files, applications and multiple tasks efficiently. Its 4 GB of LPDDR5 memory supports smooth system and application performance. A built-in NPU provides 6 TOPS of AI processing performance. The 2.5 GbE Ethernet port enables fast transfers over a local network, including for backups and multimedia tasks. Connectivity also includes two 5 Gb/s USB-A ports, one 5 Gb/s USB-C port and a microSD card reader.

Flexible storage and RAID

The four drive bays support 3.5-inch SATA HDDs and 2.5-inch SATA HDDs and SSDs. With drives of up to 32 TB each, the NAS provides up to 128 TB of raw storage; usable capacity depends on the selected array configuration. Supported configurations include Single, JBOD, RAID 0, 1, 5, 6 and 10, as well as TerraMaster TRAID and TRAID+. TRAID configurations support online capacity expansion without migrating data. Hot-swap drive replacement simplifies maintenance. Drives containing existing data can also be connected and accessed without formatting.

Photo management and file access

TOS 7 includes AI features and supports natural-language commands for controlling server functions. The Terra Photos app recognises faces, animals, objects and scenes to help organise large photo collections. Analysis takes place locally, so photos do not need to be uploaded to an external cloud service. The NAS supports backups from Windows and Mac computers, smartphones, portable drives and cloud services. TNAS Mobile provides file access and automatic smartphone photo synchronisation, while TNAS PC can mount the NAS as a local drive. TerraSync synchronises selected folders and can restore previous file versions from up to 32 saved historical versions.

Media streaming and remote access

Hardware-accelerated video decoding supports resolutions up to 4K at 60 frames per second and the H.265, H.264, VP9 and AV1 formats. DLNA/UPnP compatibility and Plex and Emby apps enable media streaming to TVs, computers and mobile devices. The TNAS.online service provides remote file access without requiring a public IP address. CloudSync can synchronise data with services including Google Drive, OneDrive and Dropbox.

Data protection and security

Redundant RAID arrays can maintain file access if drives fail, depending on the selected configuration. File-system snapshots and backups help restore data after accidental deletion or a ransomware attack. HyperLock-WORM (Write Once, Read Many) protects selected data from modification. Additional security features include AES encryption, one-time password (OTP) two-factor authentication, a firewall, IP blocking and DoS protection. Separate user accounts and folder permissions support controlled sharing with family members or colleagues.

Compact design and additional applications

The 155 × 155 × 222 mm enclosure fits on a desk or shelf. A speed-controlled 120 mm fan cools the installed drives. The noise level is 21.9 dB(A) in disk standby mode, measured at a distance of 1 m with four disks installed. Docker, Docker Compose and Portainer support additional applications and services, while Surveillance Manager can be used to build a monitoring system with IP cameras. The F4-213 can serve as network storage, a media server, a collaboration space or a surveillance recorder.
