Synology vs Terramaster NAS – Hardware Solutions Compared

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.

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.

Synology vs Terramaster NAS – Storage, Compatibility and Scalability

Storage functionality is a critical part of any NAS system, and both Synology and TerraMaster offer a wide range of capabilities here—but with distinct philosophies. Synology employs its own hybrid RAID system known as Synology Hybrid RAID (SHR), which provides flexibility in mixing different drive sizes while still maintaining redundancy. SHR is available in both single- and dual-disk fault-tolerant configurations and is fully integrated with their Btrfs-based file system, offering advanced features like snapshots, deduplication, and WORM (Write Once, Read Many). Their enterprise-class devices also support more traditional RAID configurations (RAID 0/1/5/6/10) and incorporate proprietary features like Synology RAID F1 for flash endurance. However, Synology has increasingly restricted drive compatibility on newer models such as the DS925+, requiring only their own branded HAT or SAT series drives for initialization or full functionality—a move that limits storage choices for end users.

Feature Synology TerraMaster Notes
Drive Compatibility Limited to Synology-branded drives on newer models (e.g. DS925+) Open support: WD, Seagate, Toshiba, Samsung, etc. Synology enforces verified drive policy; TerraMaster is open
RAID Support RAID 0/1/5/6/10, SHR (Synology Hybrid RAID) RAID 0/1/5/6/10, TRAID (TerraMaster RAID) Both offer flexible hybrid RAID options
File Systems Btrfs and EXT4 (model-dependent) Btrfs and EXT4 (model-dependent) Parity here; both support snapshotting on Btrfs
Snapshots Supported on all Btrfs-enabled models, with versioning & scheduling Supported on Btrfs-enabled models; varies by model Synology has more mature snapshot UI
Deduplication Btrfs-native deduplication on select models GUI-based “Dedup Manager” app available Both platforms now offer this
WORM (Write Once Read Many) Supported on all recent DSM models Available on compatible TOS models Important for compliance environments
SSD Caching Available via M.2 or 2.5” SSD (read/write) Available via M.2 or 2.5” SSD (read/write) Hardware support needed on both
Storage Pool Creation via M.2 SSDs DSM 7.2+ allows with Synology-branded SSDs only TOS 5.x+ allows with most 3rd-party M.2 SSDs TerraMaster has more flexibility here
Expansion Units Proprietary only (e.g. DX517, DX525 via eSATA/USB-C) Wider variety including hybrid M.2/HDD enclosures Synology expansion limited to official units
Third-Party Expansion Enclosures Not supported or blocked in DSM Fully supported via USB or DAS TerraMaster supports open expansion ecosystem
Max Capacity (Consumer Units) Up to 180–300TB on XS+/SA series (w/ expansions) Up to 264TB+ on Pro/Enterprise systems Similar potential; depends on model
Storage Protocols iSCSI, SMB Multichannel, NFS, AFP, WebDAV iSCSI, SMB Multichannel, NFS, AFP, WebDAV Parity on protocols
Storage Analytics / Monitoring Detailed UI with health, lifespan & usage stats Less polished UI, but includes drive info & warnings Synology more user-friendly; TerraMaster more technical

TerraMaster offers a more open storage environment, supporting standard RAID types (RAID 0/1/5/6/10) and introducing its own hybrid RAID option, TRAID, designed to dynamically balance storage allocation when using mismatched drives. Like Synology, TerraMaster has implemented Btrfs in its newer systems and supports snapshots, volume encryption, and deduplication (via its Dedup Manager) across many models. However, unlike Synology, TerraMaster places no restrictions on drive brands or third-party SSDs—users are free to populate their systems with Seagate, Western Digital, Toshiba, Kingston, or Samsung drives without concern for compatibility blocks. This openness extends to M.2 NVMe support, where TerraMaster allows NVMe drives to be used not only for cache but also for primary storage pools, something Synology currently reserves for specific enterprise-class devices or limits to caching only in most consumer models.

Where Synology shines is in the management and monitoring of storage. DSM’s Storage Manager provides a clean, user-friendly interface with visualized health metrics, smart monitoring, and snapshot replication tools. Advanced features such as scheduled integrity checks, automatic repair routines, and near-seamless volume expansion contribute to its appeal in professional environments. TerraMaster’s storage UI is functional but somewhat less polished; it provides access to core tools like volume creation, SMART diagnostics, and snapshot management, but lacks some of the refined monitoring granularity found in DSM. Still, for users who prioritize freedom of storage deployment, drive variety, and full hardware utilization, TerraMaster’s openness may outweigh DSM’s slightly more mature GUI design. Ultimately, the storage advantage between the two depends on whether the user values tight software integration or broader hardware flexibility.

Synology DSM vs Terramaster TOS NAS – Software Comparison

Synology’s DSM (DiskStation Manager) remains one of the most mature NAS operating systems available today, known for its polished interface, smooth navigation, and deep integration across features. DSM offers a fully modular, desktop-like GUI accessible through a browser, with a broad suite of first-party applications such as Synology Drive for file synchronization, Hyper Backup for multi-destination backups, and Active Backup for Business, a highly regarded solution for PC, server, and VM backups.

These tools often match or exceed the capabilities of dedicated commercial backup solutions. DSM also includes native virtualization (Virtual Machine Manager), Docker container support, surveillance management (Surveillance Station), and numerous file-sharing services including WebDAV, FTP, iSCSI, and SMB multi-channel. Overall, DSM’s ecosystem is not just well-developed—it is increasingly self-contained, with Synology focusing on reducing third-party dependencies by developing in-house alternatives for productivity, security, and media apps.

 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 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.

Synology vs QNAP NAS – Which Should You Buy in 2025?

When choosing a NAS solution in 2025, two brands dominate the conversation: Synology and QNAP. These Taiwan-based companies have evolved their offerings significantly over the years, adapting to changing user needs in backup, multimedia, virtualization, and enterprise storage. Synology, with a strong emphasis on software polish and ecosystem integration, continues to appeal to users who prioritize stability and consistency. QNAP, by contrast, leans into offering higher-spec hardware, customization, and flexibility, targeting tech-savvy users who want granular control over their system. This article explores how the two compare across hardware, storage capabilities, software platforms, security, pricing, and overall value. Both Synology and QNAP share a lot of baseline features: multi-platform support across Windows, Mac, and Linux; mobile apps for Android and iOS; web-based GUIs; encryption; multi-user access; and strong community ecosystems. Yet important distinctions emerge as you look deeper. These differences often boil down to Synology delivering a more consistent, “appliance-like” experience, while QNAP offers broader hardware choices and wider compatibility. Neither brand is universally better, but each fits different user priorities. Let’s break down how Synology and QNAP stack up in detail for 2025.

Synology vs QNAP NAS – Hardware Comparison

In terms of hardware variety and specification, QNAP clearly maintains an advantage in 2025. QNAP offers a wider range of NAS models across every price tier, providing more options for users looking for features like 2.5GbE or 10GbE ports, Thunderbolt connectivity, PCIe expandability, and support for AI or GPU cards. Many QNAP systems at even mid-tier levels offer multi-core CPUs, 2.5GbE as a minimum, and M.2 NVMe slots for caching or storage pools. Synology, while offering a hardware range from ARM-based entry units to Xeon-powered enterprise models, typically emphasizes efficiency and stability over raw horsepower, often shipping systems with lower-core-count processors and 1GbE networking by default.

Some newer 2025 Synology models do offer improvements — such as M.2 NVMe storage pools and optional 10GbE upgrades — but their pace remains slower compared to QNAP’s frequent hardware refresh cycles. For users whose priority is high performance, customization, or bleeding-edge hardware, QNAP offers far more compelling options. For those seeking low-power, quiet, turnkey systems, Synology still provides highly reliable appliances.

Synology vs QNAP NAS – Storage Services and Scalability 

Storage capabilities represent a growing area of divergence. Synology’s storage ecosystem emphasizes stability and data integrity through Btrfs file systems, SHR (Synology Hybrid RAID), fast RAID rebuilds, and snapshot technology. However, Synology has dramatically tightened its drive compatibility rules from 2025 onwards, particularly in the Plus series and higher, limiting users to certified Synology drives for initialization. This hardline approach restricts flexibility, as users cannot freely install third-party HDDs or SSDs. Meanwhile, users still benefit from technologies like SHR, making mixed-drive RAID arrays easier to manage, though concerns remain about SHR’s future viability under Synology’s evolving drive policies.

  SERVICE SYNOLOGY QNAP Notes

QNAP’s storage flexibility is far greater. Users can utilize almost any NAS-rated or server-class drive from vendors like Seagate, Toshiba, and WD, without vendor lock-in. Beyond standard RAID levels, QNAP offers Qtier for intelligent auto-tiering between SSDs and HDDs and supports ZFS through its QuTS hero operating system. ZFS integration introduces enterprise-grade features such as inline deduplication, compression, triple-parity RAID options, and even faster rebuilds. Expansion is another strong suit for QNAP, with broad support for external expansion enclosures over USB and PCIe, while Synology supports far fewer expansion units. In short, QNAP offers a more powerful, flexible storage environment but demands more technical knowledge to manage effectively.

Synology DSM vs QNAP QTS/QuTS  – Software Compared

Synology’s DSM (DiskStation Manager) remains the benchmark for NAS operating systems in terms of polish, consistency, and ease of use. Its streamlined UI, consistent app design, and stable system management tools make it highly user-friendly. DSM’s integration with Synology Drive, Hyper Backup, Active Backup for Business, and its Office suite provide turnkey productivity and backup solutions. However, Synology is moving increasingly toward a closed ecosystem, prioritizing first-party apps and services over broader third-party integration. Applications like Surveillance Station remain best-in-class, but recent trends — such as discontinuing Video Station — indicate Synology’s increasing control over its ecosystem.

QNAP’s QTS and QuTS hero systems offer greater flexibility and third-party support at the cost of consistency. Users can deploy a much wider range of apps, including those for AI recognition, media streaming, and backup tasks, often with deeper customization options. QNAP’s app ecosystem embraces both QNAP-native and third-party applications, with tools like HybridMount and Hybrid Backup Sync offering robust cloud and backup integrations.

However, design inconsistencies and a more complex setup process make QNAP platforms better suited to technically proficient users. QNAP systems offer more functionality out of the box but can feel less cohesive than Synology’s more curated environment.

Synology vs QNAP NAS – Security 

Synology continues to lead in NAS security in 2025. The company’s multi-layered approach — including an in-house Security Response Team, bug bounty programs, pen-testing partnerships, and rapid patching policies — maintains its reputation as one of the most secure NAS ecosystems. Security Advisor, SSL certificate management, encrypted folders, and proactive system audits are standard across DSM systems. Remote access via QuickConnect is tightly controlled to minimize exposure. This emphasis on hardening and responding quickly to vulnerabilities makes Synology a strong choice for users prioritizing security with minimal manual intervention.

Service Synology QNAP Notes
Security & Access 2FA (Two-Factor Authentication) ✅ ✅ User-level protection
VPN Server (OpenVPN, L2TP, PPTP) ✅ ✅ Standard features
Firewall + IP Blocking ✅ ✅ Security policy management
SSL Certificate Management ✅ ✅ Let’s Encrypt, custom certs
Security Advisor ✅ ✅ Built-in vulnerability scanner

QNAP has made substantial strides in recent years to bolster its security posture, responding to earlier criticisms following ransomware incidents. The introduction of its own PSIRT team, participation in Pwn2Own, and improvements to myQNAPcloud services represent real progress. However, QNAP’s security tools, like Security Counselor, often need to be manually installed and configured. While they now offer multi-factor authentication and SSL options, the user experience around setting up and maintaining a secure environment still lags slightly behind Synology. Power users comfortable with managing network-level protections can achieve strong security on QNAP, but casual users may find Synology’s default setup safer out of the box.

Synology vs QNAP NAS – Price Point and Value 

QNAP consistently offers better raw hardware value for the price across its product range. A mid-tier QNAP NAS typically features higher-core CPUs, 2.5GbE or 10GbE networking, and expandability features like PCIe slots and multiple M.2 NVMe slots — features that, with Synology, are only available at much higher price points.

Additionally, QNAP’s lack of strict HDD compatibility listing (as currently the case for the Synology 2025 series, at the time of writing) and broader compatibility with storage and memory components can significantly reduce the total cost of ownership for DIY-minded users. Synology’s pricing, while generally higher, reflects its software development investment and the overall polish of its systems.

Buyers are paying for a more turnkey experience, better documentation, and consistent performance across the board. Moreover, Synology’s inclusion of powerful free tools like Active Backup for Business and Synology Drive adds enterprise-grade features without additional licensing costs, which in some cases offsets the hardware premium. Nonetheless, for users whose priority is maximum hardware performance and component freedom, QNAP usually offers a stronger return on investment.

Synology vs QNAP NAS – Conclusion and Verdict 

Choosing between Synology and QNAP in 2025 depends largely on user priorities. Synology remains the best choice for users seeking a polished, consistent, stable, and secure NAS experience. Its streamlined DSM platform, reliable first-party apps, and strong support infrastructure make it ideal for small businesses, prosumers, and general users who want a “set it and forget it” solution. However, Synology’s movement toward hardware and software lock-in may be off-putting to users who value flexibility or those unwilling to buy only Synology-branded components. QNAP, by contrast, excels in offering more powerful hardware, greater configuration freedom, and broader third-party app support. Users who want to customize, expand, virtualize, and maximize their system’s capabilities — and who are comfortable managing more complex setups — will find QNAP to be the more empowering platform. While its software consistency and security history lag slightly behind Synology, the gap has narrowed considerably. Ultimately, Synology is the stronger pick for users valuing simplicity and long-term stability, while QNAP offers more opportunities for those willing to trade simplicity for flexibility and raw performance.

Buy a NAS Now or Not? – LET’S TALK TARIFFS BABY (sigh)

Par : Rob Andrews
9 avril 2025 à 17:27

The U.S. Tariffs and Their Looming Impact on NAS and Storage Tech

The United States has recently announced a sweeping set of import tariffs on goods from nearly every major trading partner in the world. This policy shift, driven largely by the country’s growing trade deficits with nations like China, the European Union, Vietnam, and others, imposes additional fees ranging from 15% to 50% on products entering the U.S. The implications go far beyond international politics—they’re about to hit consumers directly, especially in the realm of network-attached storage (NAS), data drives, and related IT infrastructure. For businesses and tech enthusiasts alike, this could drastically reshape buying decisions and the way storage technology is sourced and maintained in the years ahead.

Most NAS brands, regardless of their international reputation or market share, are headquartered—and more importantly, manufactured—outside the United States. While brands like Synology, QNAP, TerraMaster, and Asustor dominate the global NAS market, they are based in Taiwan and China—countries now subject to tariffs as high as 46%. Even U.S.-founded companies aren’t immune; Seagate and Western Digital, for instance, produce the bulk of their drives in Thailand, Malaysia, and other tariff-affected countries. Likewise, 45Drives, a Canadian company with a strong presence in the U.S. market, assembles its products in Nova Scotia. This global web of production means almost no storage brand will emerge from this tariff structure unscathed.

However, it’s not just the tariffs themselves that are concerning—it’s the uncertainty they create in the supply chain. Distributors, wholesalers, and resellers operate on tight margins and forecasting models. With the risk of sudden pricing hikes or shifts in demand, many are likely to reduce inventory levels rather than gamble on unstable costs. If distributors begin ordering fewer units or delaying shipments while waiting for clarity, that can result in long-term effects on availability down the chain. For consumers and IT professionals, this may translate into fewer options, slower shipping times, and inconsistent stock at retailers, especially for higher-end or business-class hardware.

This reduction in stock won’t be immediately obvious but will likely manifest in 3 to 6 months as upstream inventory runs out. Unlike the global chip shortages of previous years—which were driven by raw material scarcity and manufacturing delays—this looming shortage will stem from financial caution and policy volatility. Retailers might maintain listings but hold little-to-no actual stock, while lead times on specialized or enterprise-grade NAS solutions could stretch uncomfortably long. Resellers will be hesitant to overstock and risk capital loss, creating an environment where supply is bottlenecked before it even hits the storefront.

Another critical layer is the manufacturing cost ripple effect. Even products partially or fully assembled in the U.S. will see increased base costs if their components—be it PCBs, chips, enclosures, or storage platters—originate from affected countries. These costs are added long before the end product even appears on a website or in a store. What this means is that even before the tariff surcharge is applied to the final product, the wholesale cost has already been inflated. Once one manufacturer adjusts their pricing to reflect these new realities, competitors are likely to follow. The result will be a new pricing baseline that is unlikely to ever return to previous levels, even if some tariffs are eventually eased.

Some may hold out hope that this will prompt a new era of domestic manufacturing, particularly for brands looking to sidestep tariffs altogether. While this is a possibility, it’s far from an immediate solution. Setting up manufacturing in the U.S. involves immense logistical, financial, and regulatory challenges. Even if companies begin the process today, meaningful change is at least two to three years away. And critically, even if production is moved stateside, prices are unlikely to fall—once the market accepts a higher cost structure, manufacturers rarely roll back pricing, especially if demand remains strong. Historically, many brands have relied on international redistribution centers to navigate or lessen the impact of tax and tariff regimes. Countries like Singapore, Thailand, and the Netherlands have served as strategic re-export hubs, helping companies reduce costs and navigate trade restrictions. These setups have allowed goods to flow more freely into Western markets with minimal added expense. However, the comprehensiveness of the new U.S. tariff list is expected to close many of these loopholes. As more countries are swept into the tariff net, fewer workarounds remain viable, which means both gray market and authorized resellers will struggle to avoid passing costs along to the buyer.

This brings us to the practical question: should consumers and businesses buy their NAS systems now or wait? While there’s no one-size-fits-all answer, those who anticipate needing storage solutions in the next three to six months may be better off acting sooner. The intersection of declining stock availability, rising manufacturing costs, and pending tariff implementation could create a narrow window where current prices and availability are the best we’ll see for a while. Delaying too long risks not only paying more but facing potential wait times for critical systems. That said, users with stable systems and strong backup routines may prefer to ride out the uncertainty, at least temporarily. Ultimately, the storage industry—like much of the tech sector—is facing a period of turbulence. Boardrooms across the globe are likely holding emergency meetings to re-evaluate supply chains, regional assembly strategies, and consumer pricing models. But without clear long-term policy direction, many companies will be hesitant to make bold changes, opting instead for a wait-and-see approach. For now, the best advice is to monitor inventory levels closely, stay informed about regional pricing trends, and—if you’re in the U.S.—think seriously about whether a short-term investment in your storage infrastructure might save you money and headaches down the line.
