Synology VS Terramaster NAS Drives in 2025 – Which One Deserves Your Data?

Synology and TerraMaster are two well-established brands in the network-attached storage (NAS) industry, each targeting a range of users from home enthusiasts to small and medium-sized businesses. Synology, a Taiwanese company with over two decades in the field, is widely recognized for its DSM (DiskStation Manager) software, which emphasizes stability, security, and integration within a tightly controlled ecosystem. TerraMaster, while newer to the market, has steadily gained ground by offering hardware-focused, cost-effective solutions with increasing software support via its TOS (TerraMaster Operating System) platform.

I want to provide a side-by-side comparison between Synology and TerraMaster as they stand in 2025, focusing on the real-world differences in hardware, storage, software, and security. The goal is to outline the practical strengths and weaknesses of each brand without leaning heavily toward subjective preferences or historical bias. This is especially relevant for users reevaluating Synology due to recent policy shifts, or for those considering TerraMaster as a flexible and affordable alternative.

When evaluating Synology’s hardware catalog, the company demonstrates a clear strategy of segmenting performance tiers through tightly integrated systems. The FS (FlashStation) series targets ultra-low latency workloads with powerful multi-core CPUs and all-flash designs. For instance, the FS6400 and FS3600 offer 240,000 and 195,000+ 4K random write IOPS respectively, built for high-throughput environments. The HD series goes a different direction, pushing density with up to 300 drives in models like the HD6500, which pair with dual 10-core CPUs and provide over 6,600 MB/s throughput. Meanwhile, the SA and XS/XS+ series address scalable performance and redundancy needs, offering dual-controller setups, high RAM ceilings, and optional Fibre Channel or 25/40GbE expansion. Synology’s Plus and Value series provide consumer-grade flexibility, but these are becoming increasingly closed ecosystems with limited hardware compatibility and optional expansion cards restricted to specific interfaces or models.

Category	Synology Example Models	TerraMaster Example Models	CPU & RAM Range	Typical Use Case
Entry-Level (2-4 Bay)	DS223, DS423, DS224+, DS423+	F2-212, F4-223, F4-210	Quad-core 1.7–2.2GHz, up to 32GB ECC	Personal cloud, backups, media streaming
Mid-Range (4-6 Bay)	DS1621+, DS1522+, DS1821+	F4-424, F6-424, F4-424 Pro	Quad-core 2.2GHz, up to 32GB ECC, NVMe cache	SOHO/SMB file sharing, light virtualization

Enterprise / Rackmount	RS4021xs+, SA6400, SA3610, UC3200	U12-500 Plus, U16-722-2224, T12-450	10–12 core CPUs, 128GB+ RAM, SAS, PCIe expandability	Virtualization clusters, iSCSI SAN, backups at scale
All-Flash / NVMe Focused	FS2500, FS3600, FS6400, SA3400D	F8 SSD Plus, U8-522-9400, U24-722-2224	8–24 cores, all-SSD, 10/25/40GbE, NVMe-only storage	High IOPS databases, virtualization, low-latency workloads

TerraMaster, in contrast, focuses its value proposition heavily on maximizing hardware capabilities per dollar. Even in their midrange, systems like the F6-424 Max or F4-424 Pro include Intel Celeron or i3 CPUs, 2.5GbE or 10GbE connectivity, NVMe SSD support, and upgradeable RAM—all within sub-$700 price ranges. Larger units like the T12-500 Pro or U24-722-2224 scale storage up to 24 bays or beyond, while still offering competitive CPUs and abundant connectivity options. TerraMaster also maintains a vast lineup of hybrid RAID-capable DAS and NAS systems, including USB 3.2 Gen 2 enclosures for fast, direct-attached storage. Unlike Synology, TerraMaster maintains open compatibility with third-party drives and offers more consistent support for M.2 NVMe storage expansion, SSD caching, and even integrated GPU support in some models.

Overall, while Synology’s premium hardware—especially in enterprise segments like FS, HD, and SA series—is clearly capable and built with specific high-performance use cases in mind, the general direction of the brand has shifted toward tightly controlled environments with gradual upgrades. In contrast, TerraMaster’s approach offers broader hardware scalability and modularity across more price points, with emphasis on high-speed networking and expansive storage configurations. For users who prioritize full hardware utilization, third-party component compatibility, or budget scalability, TerraMaster offers more flexibility. Meanwhile, users looking for tightly integrated, support-rich systems—especially in enterprise workloads—may lean toward Synology, albeit at a higher cost per feature.

 TerraMaster’s TOS (TerraMaster Operating System), currently in version 5.1 with version 6 available on select systems, has seen rapid growth in capabilities and usability over the last few years. While it doesn’t yet match DSM’s polish, it has made significant strides in offering equivalent functionality. TOS supports Btrfs-based snapshots, Rsync and CloudSync for cloud backup, Docker container deployment, and VirtualBox-based virtualization. While the latter is less tightly integrated than Synology’s VMM, it does allow for third-party VM deployment in a usable way.

TerraMaster has also developed TerraSync, a synchronization tool designed to rival Synology Drive, and supports both media management and AI-enhanced photo sorting with apps like Terra Photos. However, many of TOS’s functions rely more heavily on community-driven or open-source third-party applications, resulting in a slightly less unified experience overall.

In terms of application ecosystems, Synology’s App Center clearly offers the broader and deeper catalog, particularly for business users. First-party applications such as Synology Office, Chat, MailPlus, and Note Station deliver a productivity-focused alternative to cloud services, and their Surveillance Station software stands out as one of the most powerful NVR platforms in the NAS market.

TerraMaster’s App Center includes essential tools but lacks the same level of first-party development. However, it makes up for this in openness: TerraMaster supports a wide array of third-party and open-source platforms more freely, including Jellyfin and Unraid. Moreover, TerraMaster allows alternative operating systems like TrueNAS to be installed without voiding the warranty, which adds considerable flexibility for tech-savvy users. Overall, Synology delivers a more unified and polished software experience, while TerraMaster emphasizes adaptability, freedom, and cost

Synology vs Terramaster NAS – Security and Safety

Synology has long maintained a strong reputation in the NAS sector for prioritizing system security, and this is evident in how thoroughly security is integrated throughout DSM. Synology’s Security Advisor provides active scanning for vulnerabilities, misconfigurations, and password weaknesses, while its firewall, account protection, and IP auto-blocking features offer practical layers of defense against unauthorized access. Synology also supports comprehensive SSL certificate management via Let’s Encrypt and offers two-factor authentication (2FA) with TOTP and hardware key support. From a business continuity perspective, DSM includes native WORM (Write Once Read Many) capabilities and encrypted shared folders to protect sensitive data from tampering or deletion. Perhaps most critically, Synology operates a dedicated PSIRT (Product Security Incident Response Team), frequently publishes security advisories, and participates in high-profile vulnerability testing events like Pwn2Own—demonstrating a serious commitment to vulnerability discovery and remediation.

TerraMaster’s security offering has become more robust over recent years, particularly with the development of Isolation Mode—a unique feature allowing users to instantly sever all external access and remote services with a single click. This acts as a kill switch in the event of a suspected breach or malware event. TOS also includes a system-level security scanner that checks for basic vulnerabilities and enables 2FA, SSH restrictions, and SSL certificate deployment. While TerraMaster’s platform does not offer as many granular policy tools as DSM, it supports core protocols like OpenVPN and L2TP for secure remote access and regularly issues firmware updates in response to new threats. The company also now provides greater transparency regarding CVEs (Common Vulnerabilities and Exposures), though its advisory frequency and scope remain smaller than Synology’s.

Security Feature	Synology DSM	TerraMaster TOS	Notes
System Hardening	Proactive hardening (limited root access, secure defaults)	Moderately hardened; more configurable access	Synology limits risky configurations by design
Security Scanner	Built-in DSM Security Advisor with customizable scan depth	TOS Security Center (less detailed on TOS 5.x)	Synology provides more actionable alerts
2FA Support	TOTP-based (authenticator apps, email)	TOTP-based	Parity on two-factor authentication
SSL Certificate Support	Native Let’s Encrypt + custom certs via GUI	Let’s Encrypt + custom certs via GUI	Equal support, easy HTTPS setup
Firewall Management	GUI-based port/IP firewall with profiles	Firewall settings available (less granular)	Synology allows more granular firewall policy creation
Isolation Mode / Kill Switch	Not available	Isolation Mode disables all external access with one click	Advantage: TerraMaster for emergency lockdowns
Vulnerability Response (PSIRT)	Dedicated PSIRT, public advisories updated monthly	Less frequent disclosure, fewer details published	Synology actively discloses and patches
Security Bug Bounty Program	Yes – active white-hat reward program	No public bounty program known	Synology engages with global researchers
Third-Party App Restrictions	Limited for security; sandboxed services	More open but requires user discretion	Synology prioritizes closed ecosystem safety
Remote Access Protection	QuickConnect includes traffic relay + DDNS + 2FA	TNAS.online DDNS with isolation toggle	Both offer encrypted remote access, but Synology uses multiple layers
Malware Detection	Real-time malware scanner, browser warnings	Included scanner, but simpler in scope	DSM scanner is more active and integrated
Backup Verification	Integrity verification in Active Backup	TerraSync + cloud/USB support (manual checks)	DSM offers automated backup health reports
Surveillance Hardening	Encrypted video storage + HTTPS + IP blocklist	Surveillance App with HTTPS, still evolving	Synology Surveillance Station is more mature and secure
Ransomware History	2014 “SynoLocker” (quickly patched)	2021–22 “Deadbolt” attacks (multiple waves)	TerraMaster more affected in recent years
Update Frequency	Frequent monthly patches	Less frequent, varies by model	DSM has a consistent schedule and transparency

Despite these advancements, TerraMaster’s security record has faced scrutiny in the past due to incidents like the Deadbolt ransomware attacks. These incidents, which also affected other NAS vendors, prompted significant user backlash and a push for more proactive security updates and faster patching. TerraMaster has since responded by improving software integrity and introducing layered protection features, but the lingering perception remains that Synology maintains a stronger and more proactive security posture overall.

This perception is reinforced by Synology’s investment in ongoing vulnerability research, bug bounty programs, and a broader portfolio of security-focused tools. As it stands in 2025, Synology continues to lead in NAS security maturity, while TerraMaster has made meaningful progress—especially with unique features like Isolation Mode—but still has ground to cover in enterprise-level protections and threat response.

Synology vs Terramaster NAS – Conclusion and Verdict

Comparing Synology and TerraMaster in 2025 ultimately highlights a clear philosophical divide between the two NAS brands. Synology continues to build upon a long-standing focus on refined software, tight integration, and enterprise-grade security. Its DSM platform remains one of the most polished and feature-rich operating systems in the NAS space, offering a wide selection of first-party tools for backup, surveillance, virtualization, and secure access. However, this ecosystem is increasingly closed, with stricter hardware compatibility requirements and limited support for third-party drives, SSDs, and expansions. For users who prioritize reliability, ease of use, and support from a mature software ecosystem, Synology remains a compelling—if sometimes restrictive—option.

TerraMaster, by contrast, leans into flexibility and hardware value. Its broad portfolio includes NAS units ranging from entry-level to high-performance multi-bay SSD systems, often at lower price points than Synology’s equivalents. TOS 5.1 and the newer TOS 6 have brought meaningful improvements in UI and functionality, while still maintaining a more open approach to compatibility and user customization. Features like native Jellyfin support, VirtualBox VM deployment, and the ability to install TrueNAS or Unraid without voiding warranty make TerraMaster a standout for DIY-leaning users or those with niche requirements. However, its software, while improving, does not yet match the polish or depth of Synology DSM, especially in areas like virtualization, surveillance, and enterprise security.

In the end, choosing between Synology and TerraMaster depends heavily on user needs and expectations. Synology suits users who want a highly stable, all-in-one solution with minimal configuration and long-term support. TerraMaster offers greater adaptability and value for power users who are comfortable managing third-party apps and want to stretch their hardware investment further. Neither approach is inherently better—each has its strengths and trade-offs. Buyers seeking a tightly controlled, secure environment may gravitate toward Synology, while those who value hardware scalability, open software choices, and affordability may find more freedom with TerraMaster.
