If you ask for my opinion as a tech journalist, I would say having a NAS is a necessity. TerraMaster today launches their flagship F2-425 Plus and F4-425 Plus NAS devices. The new 425 series is engineered to deliver professional-grade performance and storage flexibility for modern homes, creative professionals, and small offices.
With a full transition to a robust Intel N150 processor, the F2-425 Plus and F4-425 Plus represents a comprehensive upgrade over its predecessors (the F4-423 and F4-424). Compared to ARM-based alternatives, it achieves up to a 40% performance boost compared to ARM-based alternatives.
Boasting hybrid storage capacity, AI-enhanced multimedia capabilities, and an intelligent software ecosystem, the new devices set a new benchmark for smart home and business data management.
Powered by an Intel quad-core processor with a burst frequency of up to 3.6 GHz, Terramaster’s latest devices combine efficiency and speed to deliver seamless multitasking and accelerated workloads. It is equipped with fast DDR5 memory (expandable to 32 GB) to ensure responsive performance across demanding applications.
Engineered for hybrid storage flexibility, the F2-425 Plus and F4-425 Plus support multiple disk slots for 3.5″ and 2.5″ SATA HDDs or SSDs and integrates three M.2 2280 NVMe slots (PCIe 3.0 x1). This innovative design allows a total storage capacity of up to 144 TB (30TB x4 + 8TB x3) for the F4-425 Plus. The triple NVMe slots can serve as cache accelerators or be incorporated into storage pools, optimising performance and cost-efficiency while supporting TerraMaster’s TRAID and TRAID+ array configurations for enhanced read/write speed and data security.
For speed enthusiasts, Terramaster’s latest devices provide dual 5GbE network ports, achieving transfer rates up to 1010 MB/s, doubling the throughput of previous models. Its hardware encryption engine with AES-NI technology safeguards data integrity without compromising performance. The hardware transcoding engine supports H.264, H.265, MPEG-4, and VC-1 formats with up to 4K (4096 x 2160) resolution at 60 FPS, enabling smooth video streaming and real-time transcoding for media professionals.
The NAS delivers comprehensive backup and data protection capabilities through the Business Backup Suite (BBS), including Duple Backup, Centralised Backup, TerraSync multi-device synchronisation, CloudSync recovery, and Snapshot ransomware protection. Businesses benefit from role-based permissions, shared folders, and TNAS online remote access, simplifying collaboration and workflow efficiency.
Security remains a cornerstone of the design, incorporating 256-bit TLS transmission, OTP two-factor authentication, SPC app protection, and HyperLock-WORM tamper-proof technology to ensure robust defense against data breaches and unauthorised changes.
A standout feature of the F2-425 Plus and F4-425 Plus is its AI-powered photo management system, utilising local algorithms to recognise faces, pets, objects, and scenes for automatic album creation. This privacy-first design operates entirely offline, guaranteeing that personal data never leaves the device.
The new models also excel in virtualisation and multimedia performance, supporting Docker and VirtualBox for efficient container and VM management. The models also have integrated Intel graphics and are capable of handling 8K video decoding and fully compatible with Plex, Emby, and Jellyfin, transforming it into a premium home entertainment hub.
Surpassing its predecessors, the F4-423 and F4-424, TerraMaster’s new models introduce dual 5GbE connectivity and a triple M.2 SSD slot architecture, marking a new era in hybrid NAS performance. From tech enthusiasts exploring AI organisation and virtualisation to small businesses seeking secure collaboration, and home users building multimedia centers, the F4-425 Plus and F4-425 Plus redefine the benchmark for next-generation network storage.
