This article covers TERRAMASTER F4-425 Plus NASストレージ.

Overview

The TERRAMASTER F4-425 Plus is a 4-bay NAS designed for home users and small offices. It packs an Intel N95 quad-core processor (up to 3.6GHz) and 8GB of DDR4 memory, offering a solid balance of performance and power efficiency. The unit supports up to 144TB of raw storage and features three M.2 NVMe slots for caching or dedicated storage pools. Dual 5GbE LAN ports are the standout connectivity feature. With link aggregation or SMB multichannel, you can achieve sequential read/write speeds of up to 1020MB/s. This makes the F4-425 Plus a strong candidate for video editing workflows, large file sharing, and backup tasks. The chassis is built from aluminum alloy with tool-less, push-lock HDD trays. It ships as a diskless model, so you choose your own drives based on your capacity and budget needs.

Connectivity & Compatibility

Network: 2× 5GbE RJ-45 ports supporting 802.3ad link aggregation and SMB multichannel. Storage Bays: 4× 3.5-inch SATA HDD/SSD (hot-swappable, up to 144TB total). M.2 Slots: 3× M.2 NVMe SSD slots (can be used as cache or independent storage pool). USB: 2× USB 3.2 Gen 2 Type-A ports for external drives or backup devices. OS Support: Windows, macOS, Linux. Remote access via TNAS mobile app. File Systems: EXT4, Btrfs. Supports TRAID (TerraMaster's proprietary RAID management).

Product Info

The F4-425 Plus launched in late 2024 and sits in the mid-range NAS segment. The Intel N95 CPU and 8GB RAM keep costs down while delivering enough horsepower for file serving, media streaming, and light virtualization. Price: Approximately ¥110,000 (diskless). Warranty: 2 years (manufacturer standard). Accessories: Power adapter, Cat.6 LAN cable, quick install guide, screws. Availability: and major online retailers.

Best Use Cases

Home file sharing & media server: Share photos, videos, and documents across family devices. The TNAS mobile app provides remote access, and Plex/Emby/Jellyfin run smoothly for media streaming. Small office / creative team: Dual 5GbE networking enables fast concurrent access for multiple users. Ideal for sharing video editing project files or acting as a centralized backup target. Docker & VM experimentation: The Intel N95 supports virtualization extensions (VT-x, VT-d), allowing you to run Docker containers, Portainer, or lightweight virtual machines. Great for learning server administration. Who should skip: If you rely heavily on real-time 4K HDR transcoding, the N95's integrated GPU may struggle. Consider a higher-tier model like the F5-425 with a more powerful CPU for transcoding-heavy workloads. ## Alternatives
Key competitors in the same price bracket include the QNAP TS-464 (Intel Celeron N5095, dual 2.5GbE, HDMI output) and the Synology DS423+ (Intel Celeron J4125, mature DSM ecosystem). The F4-425 Plus stands out with its dual 5GbE ports and three M.2 slots. If you need fast caching or a dedicated NVMe storage pool, it offers more flexibility than either QNAP or Synology at this price. However, users invested in the Synology or QNAP app ecosystems may find TOS 6 less polished.

Things to Consider

Diskless model: You must purchase HDDs/SSDs separately. Factor that into your total budget. Transcoding performance: The Intel N95's iGPU is entry-level. Real-time 4K HDR transcoding may not be smooth. OS learning curve: TOS 6 is intuitive, but users coming from Synology DSM or QNAP QTS may need time to adapt to the interface and app layout. Noise and heat: With four HDDs fully populated, fan and drive noise can become noticeable. Place the unit in a study or utility room rather than a living area.
