With a blend of strong hardware, advanced networking, and flexible storage options, this NAS delivers a smooth experience for heavy workloads and daily use.
Performance and Hardware Power
At the heart of the F4-425 Plus is the Intel N150 Quad-Core processor, capable of reaching up to 3.6GHz. Paired with 16GB of fast DDR5 RAM, it ensures quick response times and effortless multitasking, even when running multiple services at once. TerraMaster also includes three M.2 SSD slots, which can be used for SSD caching or as separate storage pools. This combination makes it ideal for tasks like 4K editing, database hosting, and virtualization.
High-Speed Networking for Fast Access
To support heavy workloads, the NAS comes with dual 5GbE LAN ports. These ports support link aggregation and SMB Multichannel, allowing the system to reach speeds up to 1020 MB/s read and write. Whether you’re a video editor transferring large projects or a small office accessing centralized data, the F4-425 Plus ensures minimal waiting time and smooth file operations.
Flexible Storage with Strong Data Protection
The NAS supports up to 144TB of combined storage across HDDs and M.2 SSDs, giving users ample room for projects, media libraries, and backups. It includes TRAID, TerraMaster’s smart storage technology that balances capacity and data protection. Security is further strengthened with TFSS snapshots and HyperLock-WORM, protecting important data from accidental changes, corruption, or ransomware.
Versatile Use Cases for Professionals and Home Users
From Docker containers to virtual machines, the F4-425 Plus handles advanced workloads with ease. Businesses can rely on TerraMaster BBS for automated backups, while home users enjoy smooth streaming through Plex, Emby, or Jellyfin with support for 4K and even 8K content. The NAS also includes built-in apps like qBittorrent and Transmission for easy downloading, and the TNAS Mobile app enables remote access and monitoring anytime.
Smart Design and User Convenience
Designed for reliability, the device features a sturdy aluminum-alloy body and secure Push-Lock HDD trays. A standout feature is Direct Data Drive Mounting, which lets users install TOS 6 on a new drive and then hot-plug old drives without formatting. This prevents data loss and ensures immediate access, making upgrades and migrations effortless.

Ultra-Fast Performance for Heavy Workloads
The D1 SSD Plus delivers 40Gbps high-speed transfer performance, making it ideal for tasks that require instant access to large files. When paired with a high-end SSD like the 990 PRO 4TB, it achieves impressive speeds of up to 3853 MB/s read and 3707 MB/s write. This means even a 3GB file transfers in just one second, giving editors, designers, and data-heavy professionals a smoother, more efficient workflow. Whether you’re handling 4K video editing, massive backups, or frequent file migrations, this enclosure ensures lightning-fast performance every time.
Wide Compatibility Across Devices

This flexibility allows users to switch between computers, consoles, and workstations without losing speed or functionality.
Premium Design, Silent Cooling & Durability
The D1 features an elegant fanless all-aluminum body that keeps noise levels at zero during operation. Its triple-size heat dissipation design ensures stable temperatures even during high-speed transfers or extended workloads. Built to be rugged and compact, it’s perfect for travel, on-site shoots, or harsh environments where durability matters as much as speed.
Expandable Storage with NVMe SSD Support
Supporting M.2 NVMe 2280 SSDs up to 8TB, the D1 SSD Plus offers outstanding storage flexibility. It works excellently as an external expansion drive for Mac mini, giving users high-speed storage that feels like an internal drive. It can also function as a bootable macOS system drive, providing instant startup and smooth system performance.
Powerful Backup Features for Data Protection
The D1 SSD Plus goes beyond raw speed by offering multiple backup tools. With the TDAS Mobile App, users can easily back up photos and videos from iOS or Android smartphones. Windows users get access to TPC Backupper, which supports scheduled and automated backups. This makes the enclosure a practical all-in-one backup hub for work files, project data, and personal media.
