Terramaster F4 SSD NAS Review – Design and Storage

The TerraMaster F4 SSD adopts a compact, minimalist design that is clearly optimized for silent, flash-only operation. Measuring just 138mm x 60mm x 140mm and weighing 0.6 kg, it is one of the smallest 4-bay NAS chassis on the market, aided by its exclusive use of M.2 NVMe SSDs instead of traditional 3.5-inch hard drives. This all-flash design allows the chassis to maintain a reduced footprint while still offering significant internal capacity—up to 32TB using four 8TB drives. The unit features a clean, industrial aesthetic with smooth surfaces and subtle branding, aligning with TerraMaster’s recent design choices in their SSD NAS series. Importantly, the internal layout supports top-to-bottom convection airflow, with side ventilation and smart fan controls designed to balance cooling and acoustics.

Installation is clearly a design priority here. The F4 SSD uses a toolless construction held together by a single thumbscrew, allowing the user to remove the outer casing in seconds. Internally, SSDs are inserted via a pull-out drawer mechanism with dedicated mounting trays, and there’s ample clearance around each M.2 slot for installing large passive heatsinks.

Notably, the SSD slots are laid out in such a way that their orientation lines up directly with the two 50mm rear fans. These fans are positioned to channel airflow across both the SSDs and the large passive heatsink mounted over the Intel N95 CPU, ensuring that even under sustained workloads the thermals remain controlled without relying on noisy active cooling systems.

The internal storage configuration is somewhat mixed in terms of interface speed. Of the four M.2 slots, two operate over PCIe 3.0 x2 lanes, and two are limited to PCIe 3.0 x1. This introduces a disparity in potential transfer speeds—approximately 1.6GB/s per drive for the faster pair, and around 700-900MB/s for the slower ones.

While this approach is a practical trade-off due to CPU lane limitations, it may pose bottlenecks in RAID scenarios where all four drives are used in a single pool. However, for users willing to configure their SSDs into two independent volumes, or who rely on TerraMaster’s TRAID system with mixed-capacity drives, the system can still make efficient use of available bandwidth.

The F4 SSD supports a range of RAID configurations including TRAID, TRAID+, RAID 0, 1, 5, 6, and 10, as well as JBOD and single-drive modes. TRAID, TerraMaster’s hybrid RAID system, is especially notable here as it supports storage expansion using drives of different sizes—an advantage for users who plan to incrementally upgrade their SSDs over time. This flexibility is rare in entry-level NAS units, and helps avoid the traditional pitfalls of having to replace all drives at once in standard RAID arrays. The software layer automatically calculates parity and adjusts volume size without requiring complete data migration or reconfiguration.

From a practical perspective, the move to SSD-only architecture enables faster access times, reduced power usage, and significantly lower noise. TerraMaster reports a typical power draw of just 32W under full load with four SSDs, around 11-13W with all 4 SSD in a ‘read state’ with the CPU at sub 5%, and only 8W in complete hibernation. The fan noise sits below 19dB during idle operation, placing it among the quietest NAS units available. For environments such as living rooms or bedrooms where noise sensitivity is key, this silent thermal design makes the F4 SSD particularly well-suited for home multimedia centers and always-on photo backup servers.

Terramaster F4 SSD NAS Review – Internal Hardware

At the heart of the TerraMaster F4 SSD is the Intel N95 processor, a quad-core, four-thread CPU based on the Alder Lake-N architecture. Clocked at a base frequency of 1.7GHz with a boost up to 3.4GHz, it offers efficient processing power with a low 15W TDP, which contributes to the unit’s low thermal output and power consumption. While not designed for heavy computational workloads, the N95 supports Intel Quick Sync for hardware-accelerated video transcoding and includes integrated UHD graphics capable of handling 4K@60Hz decoding.

This makes the F4 SSD suitable for multimedia servers like Plex or Jellyfin, which are supported out of the box by TerraMaster’s TOS operating system. The CPU also provides nine PCIe Gen3 lanes for connecting NVMe drives, network interfaces, and USB ports—something that TerraMaster appears to have carefully balanced across components.

The system is equipped with 8GB of DDR5 memory pre-installed in a single SODIMM slot, with support for up to 32GB. The memory is non-ECC, which is expected for this price bracket and CPU class, though some users may view this as a drawback in data-critical environments. DDR5 support is a notable inclusion, offering higher bandwidth and lower power consumption than DDR4.

Because there is only a single memory slot, upgrades require replacing the pre-installed module entirely, but access is straightforward thanks to the removable chassis design. Combined with the N95 CPU and SSD storage, the memory allows for lightweight virtualization, Docker container deployment, and simultaneous access by multiple users—within the limitations of the CPU’s architecture.

Internally, the F4 SSD supports four M.2 2280 NVMe drives: two connected via PCIe 3.0 x2, and two via PCIe 3.0 x1. This setup is a direct consequence of the limited PCIe lane count on the N95 CPU, and reflects a compromise between cost and performance. While this layout means that users may encounter performance bottlenecks if building a single RAID array across all four slots, TerraMaster’s OS allows for flexible configuration, including the creation of separate volumes. The system also includes a substantial heatsink on the CPU and aligns airflow directly over both the CPU and storage bays. Together, these components form a power-efficient, quiet, and competent NAS platform optimized for SSD workloads.

Terramaster F4 SSD NAS Review – Ports and Connections

The TerraMaster F4 SSD is equipped with a practical selection of ports that reflect its mid-tier positioning. The standout feature is a single RJ-45 5GbE Ethernet port, offering five times the bandwidth of standard Gigabit connections and double that of 2.5GbE. This enables significantly faster file transfers when paired with compatible switches or direct-to-PC connections, making it a viable solution for photo and video editing over the network. However, the inclusion of only one network port—without redundancy or support for link aggregation—limits failover options and prevents more advanced networking setups, a drawback that may be felt in business or multi-user deployments. Users seeking dual LAN ports for redundancy or trunking will need to resort to USB-to-Ethernet adapters, which are supported via the system’s high-speed USB 3.2 ports.

In addition to its network interface, the F4 SSD features three USB 3.2 Gen 2 ports rated at 10Gbps each—two Type-A and one Type-C. These ports support a variety of functions, including attaching external storage for backups, connecting USB-based 2.5GbE/5GbE adapters, or even interfacing with uninterruptible power supplies (UPS). This level of connectivity is somewhat uncommon in compact SSD NAS systems and adds useful flexibility, particularly for users operating the unit as a personal cloud or remote access point. Notably absent, however, are legacy USB 2.0 ports or additional network expansion slots (such as PCIe or SFP+), which would have extended the F4 SSD’s upgradeability for more advanced users.

On the display side, the NAS includes a single HDMI 2.0b port, allowing for direct output of its graphical interface or multimedia playback, though this feature is seldom used in headless NAS operation. Still, its presence supports limited desktop use cases or direct-attached displays for VM consoles and Docker GUIs. Internally, the Intel N95 CPU provides up to three display outputs, but only one is exposed in this system. The absence of a VGA port, PCIe expansion slots, or front-facing ports keeps the design clean but does reduce options for advanced customization. Ultimately, the F4 SSD provides just enough I/O for mainstream home or small office use, while intentionally leaving out more enterprise-grade connectivity.

Terramaster F4 SSD NAS Review – TOS Software and Services

The TerraMaster F4 SSD ships with TOS 6, the company’s latest revision of its NAS operating system. TOS 6 has matured significantly compared to earlier versions, now offering a more stable and responsive interface with support for modern NAS functionality. The OS features a multi-window desktop-like environment accessible via browser, along with mobile and desktop clients for streamlined access.

The interface, though less polished than Synology’s DSM, has seen improvements in usability, with clearer organization of applications, settings, and user tools. Key system features include centralized backup, file indexing, user/group controls, and integrated snapshot functionality for shared folders and iSCSI volumes. For home users and prosumers, these updates represent a notable step forward, especially when paired with the low latency benefits of SSD storage.

Among TOS 6’s more prominent features is TRAID (TerraMaster RAID), a hybrid RAID system designed to offer flexible storage expansion and mixed-capacity drive support. Similar in principle to Synology’s SHR, TRAID allows users to start with a small number of SSDs and expand later with larger ones without reconfiguring the entire array.

This flexibility is especially useful in all-flash systems where high-capacity SSDs can be cost-prohibitive to install all at once. In addition to TRAID and TRAID+, the system also supports traditional RAID levels (0, 1, 5, 6, 10), JBOD, and single-drive configurations. Volume expansion, RAID migration, SSD TRIM, and S.M.A.R.T. monitoring are supported natively, along with scheduled snapshots and USB-based backups.

TOS 6 includes a growing suite of first- and third-party applications that address multimedia, surveillance, and cloud connectivity. The F4 SSD supports Plex Media Server, Jellyfin, Emby, and TerraMaster’s own Multimedia Server for DLNA/UPnP streaming. Users can also deploy Docker containers, virtual machines, and network services such as iSCSI, FTP, WebDAV, and VPN servers.

Multimedia support is further bolstered by hardware-accelerated 4K video decoding via the Intel UHD iGPU, making the NAS suitable as a home media hub. AI photo indexing is also integrated into Terra Photos, allowing automated categorization of people, pets, and scenes. For mobile users, the TNAS app offers automatic photo/video uploads and remote file access, enhancing backup automation and content management.

Enterprise and security features are present but modest. TOS 6 includes AES-encrypted folders, SSL certificate import, two-factor authentication, and alerting via email or desktop notifications. Integration with AD domains and LDAP clients is supported, but ECC memory is not, reflecting the system’s home and small-office focus. Additional cloud integration is provided via CloudSync, which supports Google Drive, OneDrive, Amazon S3, Dropbox, Baidu, and Alibaba Cloud.

For users requiring simple hybrid-cloud backups or syncing across multiple platforms, this unified interface is functional and sufficient. While TOS lacks the enterprise depth of some competing NAS platforms, its overall range of applications and services is now competitive for most home or light professional needs.

7 juillet 2025 à 15:00

Best NAS You Can Buy Right Now (Mid-2025) for Under $499

As of mid-2025, the sub-$499 NAS market is more competitive than ever, with several brands offering systems that deliver strong hardware, dedicated operating systems, and multiple drive bays within a modest budget. For home users, prosumers, and small teams looking to centralize data, manage backups, or stream media locally, this price bracket now includes options that would have cost significantly more just a few years ago. From rackmount storage appliances to compact flash-based servers, there are now choices to suit a wide variety of workloads and network environments.

This article examines five out-of-the-box NAS systems that are currently available for $499 or less. While each system takes a slightly different approach—whether prioritizing raw bandwidth, containerization, virtualization support, or software simplicity—they all represent viable solutions for users seeking value without compromising core functionality.

Important Disclaimer and Notes Before You Buy

All of the NAS systems featured in this list are diskless, meaning they do not include storage media by default. Users will need to purchase compatible 3.5″ HDDs, 2.5″ SSDs, or M.2 NVMe drives separately depending on the system’s configuration. This significantly affects the total cost of ownership, particularly for all-flash systems where NVMe drives are required. Some devices also use onboard flash or eMMC storage to house the operating system, but this is not sufficient for general file storage. Buyers should also consider the cost of drives, RAID redundancy planning, and any accessories (e.g., cables or cooling enhancements) when budgeting for deployment.

Another consideration is the variation in NAS operating systems provided. While most models come with a vendor-specific OS—such as Synology DSM, TerraMaster TOS, UGOS, or Unraid—some platforms allow or even encourage the installation of third-party alternatives like TrueNAS or Unraid without voiding hardware warranties. However, in cases where the software stack is less mature or limited in features, users may need to invest more time configuring services such as Plex, Docker, or SMB sharing manually. As such, these systems are best suited to users who are comfortable managing basic network services or are willing to explore more advanced functionality over time.

The Synology DS425+ is a 4-bay NAS designed to serve as an entry point into Synology’s DSM ecosystem, offering a balance between hardware efficiency and access to a mature, enterprise-grade operating system. It runs on the Intel Celeron J4125 processor, a quad-core chip with a base frequency of 2.0GHz and a burst frequency of 2.7GHz. The system ships with 2GB of DDR4 non-ECC memory, expandable up to 6GB, and supports both 3.5″/2.5″ SATA drives and two M.2 NVMe SSDs for caching or storage volumes. For networking, it includes one 2.5GbE port and one standard 1GbE port, giving users some flexibility depending on their switching infrastructure.

DSM (DiskStation Manager) remains one of the most advanced NAS operating systems available, offering built-in apps for file management, media streaming, surveillance, and virtualization. Synology Hybrid RAID (SHR) is supported for flexible storage management, along with Btrfs file system benefits such as snapshots and data integrity checks. The DS425+ is part of Synology’s 2025 refresh lineup, which enforces stricter compatibility with Synology-branded drives. Users should confirm drive support in advance, particularly if planning to reuse existing disks. Despite these limitations, for users seeking reliability, security features, and long-term OS support, the DS425+ remains a strong choice at the $499 price point.

The NAS market under $499 in mid-2025 presents a broad spectrum of options tailored to different storage priorities and technical requirements. Whether you’re looking for high-capacity traditional RAID storage, SSD-focused performance, or a feature-rich operating system, there are viable choices within this price bracket. The UniFi UNAS Pro stands out as a pure storage appliance with 10GbE connectivity and seven bays, suited for high-throughput archival or backup scenarios. Meanwhile, the UGREEN DXP4800 and LincStation N2 offer hybrid and full-flash storage respectively, with both systems supporting modern features like Docker, virtualization, and optional third-party OS deployment. For those focused on user-friendly software ecosystems and long-term support, Synology’s DS425+ remains a leading contender, albeit with stricter drive compatibility requirements. On the other hand, the TerraMaster F4 SSD delivers compact all-SSD storage with high-speed 5GbE networking and a growing feature set in TOS, including AI photo management and multimedia tools. All five models require user-supplied storage media and, in some cases, benefit from user familiarity with setup or configuration processes. Ultimately, the best choice depends on how much weight you place on performance, expandability, software polish, and overall system control within this tightly priced segment.
