100 Reasons Turnkey (Synology/QNAP/etc) are BETTER than DIY NAS (TrueNAS, UnRAID, Proxmox)

I think most users who use out-the-box NAS solutions (also known commonly as ‘turnkey‘) will admit that, although they hear alot of good things about TrueNAS and UnRAID (as well as Proxmox, OMV and ZimaOS) – there are plenty of reasons why they have not jumped ship from their Synology or QNAP yet. No one can argue that the low resource and flexibility of UnRAID, or the power and scalability of TrueNAS is not absolutely incredible – but all to often people can forget the convenience and ease of turnkey solutions – and why in 2025 that can be as appealing to us as it was back in the early 2000s, when solutions like these first appeared at retail! So, below are 100 reasons why users choose to pick and/or stay in the safe (if more expensive!) world of turnkey NAS! Some reasons are more business-focused, some more about ease of use, and others are actually more NAS brand specific (eg QNAP Qtier, Synology Active Backup, Terramaster TRAID, etc)

IMPORTANT DISCLAIMER – Different tools suit different tasks! I use both DIY and Turnkey Solutions in my own personal/work data storage environments (as well as a little bit of DAS and even some off site cloud!),. This article is not designed to ‘attack’ or ‘slag off’ one side of the home server market over another! It is to help understand why users might choose one over the other. Not disimilar in some ways to how some people prefer PC gaming vs Console gaming (or even exclusively mobile, though even struggle to wrap my head around that one!).

1. Simplified setup and onboarding

Vendor NAS software is typically ready out of the box with first run wizards, auto detection of drives, RAID suggestions and basic services pre enabled. Many users can reach a working file server or backup target in minutes without learning storage concepts in depth.

2. Unified interface across features

DSM, QTS, ADM, TOS, UGOS and UniFi Drive present storage, users, apps, snapshots, virtualisation and monitoring through one consistent GUI. In DIY platforms you often jump between different web apps, plugins or containers that each have their own interface and logic.

3. Opinionated defaults that reduce mistakes

Turnkey systems are designed around the most common small business and home use cases. They pre select file systems, background scrubs, SMART checks, scheduled snapshots and appropriate permissions. This reduces the risk of badly configured ZFS or array settings that can happen in DIY setups.

4. Integrated backup and sync ecosystem

Vendor NAS platforms usually bundle full backup suites for PCs, Macs, mobile devices, cloud sync and cross NAS replication, all controlled from one place. With DIY stacks you often assemble this from several separate tools such as Rsync, Restic, Duplicati, Hyper Backup style containers or custom scripts.

5. Official mobile and desktop apps

Synology, QNAP, Asustor, TerraMaster, UGREEN and UniFi all ship their own photo, video, music, file sync and admin apps for iOS, Android and desktop. Non technical users often rely on these instead of SMB, NFS or web portals. DIY platforms usually depend more on generic clients or community apps.

6. Vendor support and warranty alignment

When hardware and software come from the same company there is a single point of contact for troubleshooting, RMA and firmware issues. With DIY builds the user is responsible for diagnosing whether a problem is with the OS, the controller, the drives or their chosen container stack.

7. App stores and curated packages

Turnkey NAS operating systems provide an integrated app center with prebuilt and tested packages for Plex, Docker, databases, surveillance, office suites and more. Users avoid manual container creation or plugin hunting, and updates are delivered through the same update mechanism as the core OS.

8. Lower ongoing maintenance burden

Automatic OS updates, package updates, smart notifications and storage health checks are designed for people who do not want to maintain a homelab. DIY deployments like TrueNAS and UnRAID can be very stable but usually expect the admin to read changelogs, test new releases and manage hardware firmware themselves.

9. Polished UX for non technical family or staff

Many people want something they can hand to family members or colleagues without explaining datasets, pools or parity models. Vendor systems focus on friendly media apps, easy sharing links, simple user management and straightforward access control, which is less intimidating than more technical dashboards.

10. Purpose built hardware integration

Turnkey NAS software is tuned for the vendor chassis, CPU choices, fan curves, drive bays, expansion units and sometimes their own drives or NICs. This allows better power management, quieter cooling profiles and predictable performance under typical loads, whereas DIY setups sometimes require manual tweaking or custom scripts to reach the same level of integration.

11. Built in remote access services

Synology QuickConnect, QNAP myQNAPcloud, UGREEN remote access and UniFi cloud portals give relatively easy ways to reach the NAS from outside the home, with wizards for SSL certificates and relay or reverse proxy configuration. DIY solutions usually need separate VPN, reverse proxy or dynamic DNS setup, which can be a hurdle for less technical users.

12. Integrated surveillance and NVR features

Most turnkey NAS platforms bundle full camera management suites with motion detection, licensing, event timelines and mobile notification support. With DIY systems this often means combining separate containers or services and manually wiring storage, permissions and recording schedules together.

13. Smooth firmware and OS integration

Drive sleep, fan curves, thermal limits, UPS signals, LCD panels and front panel buttons are all tuned and tested by the vendor. This reduces strange edge cases such as fans stuck at full speed or drives not sleeping, which are more common when an OS is deployed on random DIY hardware.

14. Better experience for small offices and non technical teams

Turnkey NAS software is designed so that a small office without an IT department can manage users, quotas, shared folders, cloud sync and snapshots through a predictable interface. DIY stacks often assume there is a homelab style admin who is comfortable with shell access and manual recovery steps.

15. Pre integrated ecosystem services

Vendors often provide their own office suite, chat server, calendar, mail, photo and video applications that are aware of each other permissions and storage locations. Doing the same on a DIY system usually involves picking and integrating separate open source projects, each with its own user database and update cycle.

16. Clearer disaster recovery workflows

Many turnkey systems have guided workflows for replacing failed disks, expanding RAID, restoring from snapshots and recovering from another NAS or a cloud backup. DIY platforms are powerful here but often present more technical terminology and expect the admin to understand pool state, resilvering and dataset recovery in more detail.

17. Certification and ecosystem support

Synology, QNAP, Asustor and others often have official compatibility lists, certifications with backup vendors, hypervisors and camera brands, plus documentation that assumes their OS. This helps businesses that need a supported environment, rather than a custom stack that vendors may refuse to certify.

18. Predictable update cadence

Appliance style NAS software usually follows a documented release track, with security updates and feature releases pushed through a single updater. DIY NAS users often juggle OS upgrades, plugin or container updates and sometimes driver or kernel updates, which increases the risk of something breaking.

19. Lower learning curve for occasional admins

Some people only touch their NAS settings a few times per year. Turnkey software favours obvious icons, wizards and consistent terminology that are easier to come back to after a long gap. DIY environments frequently reward continuous familiarity and can feel opaque if you only log in when something has gone wrong.

20. Perceived professionalism and vendor reputation

For small businesses or freelance professionals, buying a branded NAS with an integrated OS feels closer to buying a finished appliance such as a router or firewall. This can inspire more confidence than a home built box with a community OS, even if the DIY system is technically superior, which influences purchasing decisions in many cases.

21. Built in cloud service integration

Turnkey NAS systems tend to ship with first party or curated apps for major cloud platforms such as Microsoft 365, Google Workspace, Dropbox and S3 compatible services. The wizards handle credentials, scheduling and throttling, so users do not need to wire up separate containers or command line tools for each provider.

22. Clear licensing and feature tiers

Commercial NAS platforms usually define which features are free, which require extra licenses such as camera channels or mail server and which are part of business tiers. DIY solutions often involve a mix of open source projects with different licenses plus optional paid plugins, which can be harder for a small business to audit.

23. Centralised security controls

Security options such as two factor authentication, account lockout rules, firewall profiles, certificate management and brute force protection are normally surfaced in one place in turnkey NAS software. On DIY stacks these controls may live separately in the operating system, reverse proxy, containers and hypervisor.

24. Extensive official documentation and training material

Vendors publish step by step guides, video tutorials and certification style training that assume their software stack. This makes it easier for junior staff or generalists to learn the system compared with assembling knowledge from multiple communities and wikis for a custom DIY setup.

25. Easier compliance reporting

For organisations that need to satisfy basic compliance such as audit trails, retention rules or off site backups, vendor NAS platforms often include reporting tools, logs and checklists that map to common requirements. With DIY environments the admin usually has to prove and document these controls manually.

26. More predictable multi site deployments

If several offices all use the same NAS brand, the admin can reuse the same playbook for remote management, replication, user templates and monitoring. DIY deployments may vary more in hardware and configuration between locations, which complicates support.

27. Lower barrier for third party support

External IT providers and managed service companies are more likely to have experience with popular turnkey NAS brands and their operating systems. That makes it easier to hand off support or get short term help, compared with a custom server running a niche or heavily customised DIY stack.

28. Consistent user experience during upgrades

When upgrading from an older appliance to a newer one from the same vendor, the interface, migration tools and storage layout are usually similar. This reduces retraining and migration complexity, while a move between different DIY platforms or versions can feel more like a full redesign.

29. Smaller risk of silent misconfiguration

Turnkey NAS software often validates settings and warns if you choose insecure or unsupported combinations, for example exposing services directly without encryption or mixing unusual RAID and cache arrangements. DIY tools frequently assume the admin knows the implications and allow more dangerous combinations without warning.

30. Better fit for plug and forget scenarios

Many users and small businesses want a storage appliance that they configure once, then largely ignore apart from occasional updates. Vendor NAS systems are aimed at this type of usage pattern, with notifications only when something important changes, whereas DIY environments typically reward regular attention and active administration.

31. Better out of the box media experience

Turnkey platforms usually have polished photo, video and music apps, automatic indexing and pleasant web players for family or staff. DIY systems can match this with containers such as Jellyfin, Photoprism and Immich, but the user has to assemble and maintain all of it.

32. Built in wizards for directory services

Joining Microsoft 365, Azure AD, local Active Directory or LDAP is usually handled with simple wizards and documented steps. On DIY platforms it often means more manual configuration and troubleshooting of Samba, Kerberos and certificates.

33. Language, localisation and accessibility

Commercial NAS software is usually translated into many languages and tested for right to left scripts, date formats and accessibility features such as high contrast and screen reader support. DIY tools may only be fully usable in English and have less focus on accessibility.

34. Simpler notifications and alerting

Turnkey systems offer point and click setup for email alerts, mobile push messages and sometimes vendor cloud notifications. They choose sensible defaults for what counts as an important alert. DIY environments often need separate configuration for mail relays, monitoring containers and alert policies.

35. Integration with vendor hardware ecosystem

Vendors such as Synology, QNAP and UniFi design switches, routers, cameras and sometimes drives to work together. Using their NAS software often unlocks extra features or easier management when everything is from the same ecosystem, which is harder to replicate with a mixed DIY stack.

36. Cleaner upgrade path for non technical owners

If the original tech person leaves, a small office can more easily hand a vendor NAS to a new admin or outside consultant. A heavily customised TrueNAS or Unraid box may be much harder for someone new to understand, especially if it has many manual tweaks.

37. Better power management and noise tuning

Because the operating system is written for known hardware, the vendor usually has sensible defaults for drive spindown, CPU power states and fan speed curves. DIY builds sometimes run noisier or less efficiently until the owner spends time tuning them.

38. Easier resale and re deployment

A branded appliance that can be factory reset and resold is often more attractive on the second hand market, and the buyer knows they will get a familiar interface. A DIY server with a complex configuration is harder to pass on or repurpose.

39. Simple route to official feature requests

Turnkey NAS vendors maintain public roadmaps, ticket systems and sometimes beta programs where users can request features and see progress. DIY stacks rely more on open source project maintainers and community volunteers, which can be less predictable from a non technical user point of view.

40. Clear boundary between appliance and experiments

With a vendor box, many users treat the NAS as a stable appliance and do their experimental homelab work on other hardware. With DIY NAS platforms it can be tempting to mix storage, containers, VMs and random experiments on the same system, which increases the chance of self inflicted problems.

41. Integrated health check tools

Many turnkey NAS platforms include scheduled health scans, built in diagnostics and simple one click reports that summarise disk health, file system status and security posture. This gives casual admins a clear picture of whether things are normal without reading system logs.

42. Safer default network exposure

Vendor systems usually ship with conservative defaults for open ports, remote access and admin interfaces. They often require explicit confirmation before exposing services to the internet, which lowers the chance that a newcomer accidentally leaves something critical wide open.

43. Easier mixed environment support

Turnkey NAS software is designed from the start to serve Windows, macOS and Linux clients, as well as mobile devices, with presets for each. The same applies to printer shares, Time Machine and simple guest access, so a mixed household or office can work with fewer manual tweaks.

44. Family friendly features

Photo sharing, simple link based file sharing, parental controls and easy user creation make appliance NAS platforms attractive in homes where not everyone is technically minded. It is simpler to give each family member a home folder and app than to explain datasets and user groups in a more technical system.

45. Built in small business templates

Many vendor platforms include wizards labelled for small business tasks, for example file server for a workgroup, simple off site backup or camera recording for a shop. This template approach is less intimidating than building every share, permission and schedule from scratch.

46. Integrated antivirus and security scanners

Turnkey NAS operating systems usually include built in antivirus, basic malware detection and sometimes ransomware behaviour alerts that tie directly into shares and user accounts. With DIY stacks you often need to choose and connect your own security tools, then maintain them separately.

47. Built in help and guided troubleshooting

DSM, QTS, ADM and similar platforms tend to include integrated help panels, inline tooltips and simple diagnostic wizards that walk you through common problems such as slow access or failed backups. DIY platforms rely more on forum posts and community guides, which is slower for less experienced admins.

48. Tested support for vendor expansion hardware

Vendor NAS software is checked against their own expansion cards, external drive shelves, Wi Fi or cellular dongles and specific UPS models. This removes guesswork around drivers and compatibility that is more common when you deploy a general purpose OS on random hardware.

49. Clean virtual machine and container integration

On many turnkey NAS systems the built in virtualisation and container managers are linked directly into storage, networking and permissions with a unified permission model. DIY users often combine a separate hypervisor with storage and multiple container engines, which is more flexible but also more complex.

50. Easier link aggregation and networking features

Interface bonding, vlan tagging and basic quality of service are usually exposed through simple screens that understand the appliance hardware. On DIY setups these features can require manual configuration of network stacks or external switches with less guidance.

51. Integrated energy saving and scheduling

Turnkey NAS platforms frequently offer scheduled power on and power off, automatic hibernation and coordinated UPS shutdown in one place. DIY systems can do the same, but usually through a mixture of firmware settings, operating system tools and UPS software that are not collected into a single panel.

52. Simple handling of mixed storage tiers

Many vendor operating systems make it straightforward to mix solid state cache, solid state volumes and hard drive volumes with clear labels and usage suggestions. Users who just want a fast area and a bulk area can configure this quickly, without learning detailed tiering concepts.

53. Vendor tuned media indexing and AI features

Newer turnkey NAS software often includes ready configured services for face recognition, object tagging and quick search across photos and documents. Achieving the same on DIY systems typically means deploying several separate projects and ensuring they all stay updated and indexed correctly.

54. Friendly drive swap and expansion workflows

Guided workflows for swapping drives, upgrading disk size or adding new volumes reduce anxiety for people who only perform these tasks occasionally. DIY stacks present these operations at a lower level and expect the admin to understand more storage theory before they proceed.

55. Clearer codec and patent licensing story

For video playback and some network protocols the vendor usually takes care of licensing and legal obligations in the firmware and media apps. DIY stacks often leave it to the user to add codec packs, accept legal risk or live with reduced playback support.

56. Built in tools for privacy and data requests

Some turnkey NAS platforms provide simple tools for finding and exporting user data, wiping specific accounts and managing retention rules in ways that map to common privacy regulations. With DIY systems you usually have to design and script these workflows yourself.

57. Strong vendor partner and reseller ecosystem

Many service providers build standard offerings around Synology, QNAP or other vendor platforms, including fixed price backup, monitoring and remote management bundles. A customer can buy into that ecosystem more easily than asking a provider to support a one off DIY stack.

58. Remote diagnostic bundles for support

Vendor NAS software often includes support bundles that capture logs, system state and configuration in one archive that can be sent securely to support. On a DIY NAS, collecting everything a third party needs for diagnosis often involves more manual work and explanation.

59. Formal training and certification paths

Larger NAS vendors run structured training courses and certification exams focused on their platforms. Organisations can build a team of admins with recognised skills instead of relying only on informal community learning.

60. One click configuration backup and restore

Turnkey NAS systems usually have simple configuration backup features that capture users, shares, permissions and services in a single file that can be restored to identical or successor hardware. DIY platforms often have more moving parts, so configuration is spread across several tools and locations.

61. Better integration with office printers and scanners

Appliance NAS platforms commonly provide straightforward file shares and mail relay options with clear documentation for popular multifunction printers and scanners. In many cases, scan to folder and scan to mail work with only minor setup, which is harder on some DIY stacks.

62. Hardware backed security features surfaced clearly

Where the appliance includes secure boot, dedicated security modules or signed firmware, the NAS operating system usually exposes these with clear status indicators. DIY builds can also use such features, but enabling and monitoring them often involves lower level tools and more specialist knowledge.

63. Cloud based fleet management for many devices

Several vendors now offer cloud consoles that let you see, update and sometimes configure multiple NAS units from one place. This is useful for managed service providers and larger organisations and is not commonly available for DIY installations.

64. Reduced risk of software dependency conflicts

Vendor NAS software controls the package set tightly and exposes apps through a curated store. This lowers the chance that installing one package will silently break another through shared libraries or operating system updates. DIY systems give more freedom at the cost of more potential conflicts.

65. Integrated download and ingestion tools

Turnkey NAS platforms often include a full featured download client for web, ftp, torrent and nzb sources, tied directly into shares and quota rules. Non technical users can automate downloads and have them land in the right places without learning separate tools.

66. Native calendar and contact sync services

Many appliance systems expose built in calendar and contact sync using industry standard protocols, with setup wizards for common phones and desktop mail clients. Small teams get a simple private address book and calendar without having to assemble separate groupware software.

67. Turnkey VPN server with guided client setup

Synology, QNAP and others commonly include their own VPN server packages with wizards and downloadable client profiles, so remote users can get secure access without the admin needing to deploy a separate dedicated VPN appliance.

68. Integrated reverse proxy and virtual host manager

Turnkey NAS software often lets you publish several internal apps behind a single public address using a graphical reverse proxy manager, with automatic certificate handling. On DIY systems this usually means manual web server configuration and ongoing maintenance.

69. Front panel copy and import workflows

Many branded NAS units wire the front usb port and copy button directly into the operating system, so pressing it can trigger predefined jobs such as importing photos or backing up a specific share. Replicating this behaviour on a DIY server normally needs custom scripting.

70. Effortless discovery by televisions and consoles

Vendor NAS operating systems usually ship with media servers that smart televisions and game consoles can see immediately, with almost no setup. For many households this simple living room playback is more important than advanced tuning.

71. Simple resource controls for apps and containers

Appliance platforms often expose per application limits for cpu, memory and sometimes network through sliders or basic fields in the app center. This reduces the chance that one heavy service will starve others without the admin needing to understand deeper container controls.

72. Structured beta and preview channels

Several commercial NAS ecosystems provide clearly labelled preview tracks for new features with documented rollback paths and support boundaries. Curious users can try new capabilities while still having a straightforward route back to a stable release.

73. Hardware aware media transcoding controls

Turnkey NAS software usually knows exactly which media acceleration features are present and exposes them through simple settings. Users can enable or disable hardware transcode and change quality limits without hand tuning media server parameters.

74. Native smart home and voice assistant integration

Many vendor platforms provide official skills or actions for major voice assistants and sometimes hooks for smart home platforms. This allows simple voice commands or automation rules for tasks such as checking storage status or pausing heavy jobs.

75. Unified performance monitoring and graphs

Turnkey NAS systems usually include dashboards that graph cpu, memory, network and disk activity over time. Admins get an at a glance view of behaviour without deploying a separate monitoring stack or learning specialised graphing tools.

76. Integrated snapshot browsing for end users

On many turnkey NAS platforms, users can see and restore earlier versions of files directly from the web file portal or desktop client, without needing admin access to the snapshot tools. DIY systems often expose snapshots mainly at the storage layer, which makes end user self service recovery more complicated to set up.

77. Pre defined permission and role templates

Vendor NAS software usually ships with ready made roles such as administrator, power user, standard user and guest that map to sensible permission sets. This reduces the chance of over privileged accounts and saves admins from building every permission scheme by hand, which is more common with DIY platforms.

78. Unified logging and audit views

Turnkey NAS systems tend to centralise system logs, access logs and app logs in one interface with filters and export options. Admins can quickly see who did what and when, instead of piecing together multiple log locations and formats as is typical on general purpose DIY servers.

79. Guided guest and project share creation

Appliance NAS platforms often include wizards specifically for temporary project folders or guest access, with options for automatic expiry and simple sharing links. DIY systems can do the same but usually require manual user creation, ACL tweaks and later cleanup that is easier to forget.

80. Consistent behaviour across the product range

Once someone has learned one model from a vendor, most of their knowledge applies across the whole family, even when hardware capabilities differ. Features behave in a consistent way, whereas DIY deployments can vary widely depending on how each server was built and configured.

81. Workload tuned defaults out of the box

Many vendor platforms come with presets for common workloads such as general file server, surveillance recording or virtualisation, each with tuned cache, connection and background task settings. DIY stacks often leave all the tuning to the admin and assume they understand how to optimise for each workload.

82. Multi administrator delegation with scoped access

Turnkey NAS software frequently supports multiple administrator level accounts with different scopes, for example a main system admin and a helpdesk admin who can reset passwords but not change storage. Implementing that kind of scoped admin access on a DIY stack usually demands deeper knowledge of underlying permission models.

83. Guided certificate and HTTPS management

Many appliance NAS platforms provide wizards that request, install and renew certificates from public authorities and apply them across web admin, file portals and apps. On DIY systems, certificate handling often requires manual web server configuration, file placement and periodic renewal scripts.

84. Vendor push notification channels

In addition to email alerts, turnkey NAS platforms often use vendor operated push services tied to their mobile apps and cloud accounts. This means important alerts such as disk failures or overheating can reach admins even when mail relays are misconfigured, something that is less common in DIY environments.

85. Clear support lifecycle and end of service timelines

Commercial NAS vendors publish how long each model and OS train will receive security and feature updates. That clarity makes it easier to plan hardware refreshes and budgets, whereas with DIY combinations of OS and plugins it can be harder to know which components will still be maintained in several years.

86. Offline update bundles for secure or air gapped sites

Turnkey NAS operating systems usually provide complete update files that can be downloaded once, checked and then applied to machines without direct internet access. Assembling equivalent offline update workflows for DIY stacks involves collecting OS updates, plugin updates and container images individually.

87. Dedicated tools to migrate from older or rival devices

Many vendor platforms include built in migration tools that pull data, permissions and sometimes application settings from older appliances or even competing NAS brands over the network. In DIY setups, migration is more often built around manual rsync, snapshots and recreation of users and shares.

88. Native S3 compatible object storage services

Some turnkey NAS systems include official S3 compatible endpoints that are tightly integrated with the built in user and permission model. This lets organisations expose object storage to applications without standing up and maintaining a separate object storage project on top of a DIY server.

89. Simple controls for scrubbing and integrity repair

Appliance NAS platforms typically expose data scrubbing and repair functions as a schedule choice rather than a low level command. Admins can enable regular scrubs to catch bit rot and silent corruption without needing to learn or script the underlying integrity tools.

90. Guided secure erase and decommission procedures

Many vendor NAS operating systems offer secure wipe options for entire volumes or selected shares, often including crypto erase where keys are destroyed. This makes it easier to safely dispose of or resell hardware, while DIY admins must design and verify their own data destruction workflows.

91. Predictable behaviour under partial hardware failures

Turnkey stacks are tested against common faults such as a dead fan, a missing expansion tray or a single failing drive, with clear warning messages in the GUI. DIY combinations of OS and hardware can behave less predictably when something fails, which increases pressure on the admin during incidents.

92. Wizards for expansion units and bay mapping

Where vendors sell expansion shelves, their NAS software usually provides screens that show which bay belongs to which chassis and guide the user through adding or replacing shelves. With DIY servers and generic JBODs, tracking physical bay mapping is often left to labelling and manual documentation.

93. Clean separation of admin and user facing portals

Appliance NAS platforms normally offer a clear split between the administrative interface and user portals for files, photos, mail or collaboration tools. End users rarely need to see the admin side, which reduces the risk of accidental changes compared with some DIY environments where everything is accessed in the same way.

94. Sector specific documentation and examples

Larger NAS vendors often produce guidance tailored to common sectors such as creative studios, surveillance deployments, education or small offices, including reference topologies and settings. DIY platforms rely more on generic documentation, leaving admins to translate that into sector specific designs themselves.

95. Reduced risk of command line mistakes

Because turnkey NAS systems guide most changes through the web interface and hide many low level options, there is less chance that an admin will break the system with a single incorrect shell command. DIY stacks encourage deeper shell access, which is powerful but also easier to misuse.

96. Factory reset and recovery options designed for non experts

Many vendor NAS devices include simple factory reset procedures and guided recovery wizards that bring the system back to a known state without needing installation media. On DIY servers, reinstalling or repairing the OS often involves bootable images, manual partitioning and reimporting storage.

97. Easier integration into vendor router and Wi Fi ecosystems

When a NAS, router and access points all come from the same brand, the software often includes shortcuts for service discovery, internal DNS and basic quality of service for media traffic. Recreating that level of smooth integration with a DIY NAS in a mixed vendor network typically takes more tuning.

98. Safer experimentation through vendor sandboxes or trial modes

Some turnkey NAS platforms offer limited scope trial zones or beta features that are clearly flagged and easy to disable, reducing the risk that experiments will affect core data. DIY environments can provide similar separation, but usually only if the admin designs careful virtualisation or lab setups.

99. Simple inclusion in vendor managed backup services

Vendors increasingly offer their own cloud backup platforms that recognise their NAS appliances automatically and apply sensible defaults for encryption, retention and throttling. DIY NAS users can pick any cloud they like, but must design the backup strategy, encryption and job tuning themselves.

100. Stronger non technical stakeholder confidence in the solution

Managers, clients or family members often feel more comfortable when critical data lives on a named appliance with an official operating system, public documentation and a support contract. That confidence in a recognisable product can be important even when a well built DIY alternative is technically very capable.

Nous sommes en 2026 et les choses ont pas mal évolué ces derniers mois. À une certaine époque, les systèmes DIY pour NAS se comptaient sur les doigts d’une main : ce n’est plus le cas. Aujourd’hui, on trouve des solutions très abouties, avec un niveau de qualité proche du monde professionnel, comme TrueNAS Scale ou Unraid, des options intermédiaires comme OpenMediaVault (OMV), et d’autres plus accessibles et plus souples, comme CasaOS, ZimaOS ou UmbrelOS. Nous aborderons également le cas de Proxmox…

Qu’est-ce que le DIY pour les NAS ?

Le concept de NAS DIY (Do It Yourself) repose sur une idée simple : s’affranchir du verrouillage matériel des constructeurs (Synology, QNAP, Asustor…). Au lieu d’acheter un boîtier propriétaire, vous sélectionnez vos propres composants (boîtier, processeur, RAM, contrôleurs…) ou vous recyclez un ancien PC.

Cette approche offre 2 avantages majeurs :

• Rapport performance/prix : pour le prix d’un NAS 4 baies du commerce équipé d’un processeur souvent limité, vous pouvez assembler une machine capable de gérer du transcodage 4K, des dizaines de conteneurs Docker, des machines virtuelles… 
• Évolutivité : vous n’êtes plus limité par le nombre de ports, la mémoire soudée ou les choix matériels du constructeur. Votre NAS évolue avec vos besoins.

À cela s’ajoute un point souvent sous-estimé : la possibilité de donner une seconde vie à un NAS qui ne reçoit plus de mises à jour…

Qu’est-ce qu’un système DIY pour les NAS ?

On me pose souvent la question : pourquoi parler de « système » et pas simplement de « système d’exploitation (OS) » pour NAS ?

Parce qu’en 2026, un NAS moderne n’est plus seulement un serveur de partage de fichiers (SMB/NFS). C’est une plateforme qui combine trois couches complémentaires :

• OS : généralement Linux, il gère le matériel et le système de fichiers (ZFS, Btrfs, XFS…) ;
• Interface web : outil d’administration au quotidien, qui permet de gérer stockage, utilisateurs, services, mises à jour et supervision (sans passer par des lignes de commande) ;
• Applications : écosystème de services que vous hébergez qui était la force des fabricants historiques… mais maintenant Docker est devenu central.

Les poids lourds : Performance et stockage massif

Ces solutions visent d’abord la fiabilité et une gestion sérieuse du stockage.

TrueNAS Scale : l’incontournable

Avec ses évolutions récentes, TrueNAS Scale s’est imposé comme une référence du NAS DIY. Son point fort, c’est la protection des données grâce à ZFS (snapshots, auto-réparation, intégrité), avec une approche très “pro”.

En contrepartie, ZFS reste relativement rigide : étendre un pool en ajoutant “juste un disque” n’est pas aussi souple que sur d’autres solutions. Pour exploiter ZFS dans de bonnes conditions, il est recommandé d’avoir beaucoup de mémoire vive/RAM (ECC de préférence).

Si votre priorité est la pérennité et la sécurité des données, TrueNAS Scale est un excellent choix.

Unraid : la flexibilité avant tout

Toujours très populaire chez les particuliers, Unraid brille par sa capacité à gérer des disques hétérogènes (marques et tailles différentes) avec une grande simplicité. Son système de parité permet d’ajouter un disque facilement, au fil de l’eau. Son interface est aussi l’une des plus accessibles et sa gestion de la virtualisation (VM avec passthrough GPU) est une référence pour les configurations hybrides.

Le point à intégrer dans l’équation : son modèle économique a évolué. Les mises à jour sont désormais liées à un abonnement, sauf licence à vie plus onéreuse. Cela le place face à une concurrence gratuite de plus en plus solide.

Unraid reste un excellent choix pour le multimédia, l’hébergement d’applications et le recyclage de disques, à condition d’accepter le coût de la licence.

L’intermédiaire

OpenMediaVault est construit autour d’une base Debian, avec une philosophie simple : rester léger, stable et relativement proche de Linux.

OMV tourne sur à peu près tout, y compris sur du matériel ancien. Il laisse plus de latitude pour personnaliser l’OS sous-jacent que certaines solutions plus “encadrées”. En revanche, l’interface est plus austère et demande souvent un peu plus de connaissances pour obtenir une configuration parfaitement propre (permissions, services, supervision, sauvegardes).

C’est une solution cohérente pour les utilisateurs à l’aise avec Linux qui veulent un NAS sans fioritures, sur du matériel modeste.

La nouvelle vague : simplicité et one-click

Ici, l’objectif est clair : privilégier l’accessibilité, l’expérience utilisateur et une installation rapide.

CasaOS, ZimaOS et UmbrelOS

Ces systèmes (ou surcouches, selon les cas) cherchent à transformer un serveur en « cloud personnel » facile à prendre en main. Les interfaces sont modernes, visuelles et l’installation d’applications ressemble à un App Store… On déploie des services en quelques clics, ce qui les rend attractifs pour démarrer vite.

La limite est structurelle : ce ne sont pas, à la base, des OS orientés « stockage avancé ». La gestion RAID, la stratégie de protection des données et les scénarios de migration/extension sont sommaires (rien à voir comparé à TrueNAS et Unraid).

Ils sont donc très adaptés à un premier serveur multimédia/domotique, mais moins pertinent si vous cherchez une plateforme de stockage « sérieuse » pour des données réellement critiques.

HexOS

HexOS est très attendu (toujours en Bêta), car l’ambition est séduisante : proposer la puissance d’une base type TrueNAS avec une interface beaucoup plus simple. C’est une piste intéressante pour ceux qui veulent une expérience plus « grand public » sans renoncer à une base technique solide.

Point important : c’est un produit payant. Son intérêt dépendra de son niveau de maturité et de la qualité de l’intégration au quotidien.

L’alternative : virtualisation avec Proxmox

Techniquement, Proxmox VE n’est pas un OS de NAS : c’est un hyperviseur. Mais en 2026, c’est la base de nombreuses installations homelab.

Le principe est simple : vous installez Proxmox sur le matériel (bare metal), puis vous déployez votre NAS (TrueNAS, OMV…) dans une machine virtuelle et vos autres services dans d’autres VM ou conteneurs.

L’intérêt ici, c’est que vous séparez les rôles. Vous facilitez les sauvegardes complètes (snapshots, export) et vous rendez l’infrastructure plus résiliente. Si un service tombe, le reste continue de tourner et vous pouvez restaurer proprement.

Cependant, c’est une approche plutôt réservée aux utilisateurs avancés. Elle demande une bonne maîtrise des notions de stockage (pass-through, contrôleurs, performances, sécurité des données).

Que choisir en 2026 ?

Le choix ne dépend plus uniquement des fonctionnalités (Docker est devenu un standard), mais de votre priorité? Vous voulez :

• Protéger vos données avant tout : TrueNAS Scale
• Recycler des disques variés et évoluer facilement : Unraid
• Une solution simple, légère, proche de Linux : OMV
• Une belle interface et démarrage rapide : CasaOS ou ZimaOS
• Un homelab complet et une infra modulaire : Proxmox

Certains diront que le NAS DIY est à son apogée. De mon côté, je le vois plutôt comme une étape : les outils se simplifient, les standards se consolident et le niveau de finition continue de monter. Reste à choisir l’approche qui correspond à vos contraintes… et à votre tolérance à la complexité.

5 Mistakes New NAS Buyers ALWAYS MAKE

If you are buying a NAS for the first time, it is very easy to focus on brand names, bay counts and discounts while overlooking practical issues that will shape your experience for the next 5 to 7 years. New buyers often underestimate noise in real rooms, forget to plan for future capacity growth, misjudge the usefulness of SSD cache, ignore long term power consumption, or assume that a couple of very large drives are always the best value. On top of that, many people treat a NAS like a simple external drive rather than a 24/7 network device that will sit near family members or co workers and quietly draw power every day. This article looks at 5 common mistakes that first time NAS owners make and explains how each one happens, what it looks like in normal home or small office use, and the straightforward checks you can perform before you spend any money so you do not end up with a noisy, inefficient or inflexible system.

Mistake #1: Underestimating NAS Noise in REAL-WORLD Use (IGNORE the official Specs Sheets)

A common mistake with a first NAS is to assume it will sound like a quiet router or a small external drive. In practice a NAS contains several moving parts that generate and transmit noise into the room, especially at night or in a small flat. Drive seek clicks, spindle hum, fan airflow and vibration passing into the furniture all add together. If the system ends up in a bedroom, living room or small home office, the constant whirr can lead to complaints from other people in the house and leave the owner wondering whether the device is faulty when it is simply behaving as designed. It is also easy to forget that scheduled tasks such as antivirus scans, backups and indexing will often push the CPU, fans and disks harder than normal file access, so a system that seems acceptable during light daytime use can become noticeably louder when these jobs run.

Noise levels are heavily influenced by physical design choices that new buyers rarely consider. Metal chassis units tend to amplify vibration compared with plastic enclosures, which means every drive click and fan change is more noticeable. Larger capacity HDDs, particularly above 8TB, usually contain more platters and a more active actuator assembly, which produces sharper clicks and a deeper background rumble than smaller disks. Fan design also matters. Rear mounted fans tend to push sound directly into the room, while models with downward facing or internal fans may spread the noise more evenly into the surface under the NAS. Even the desk or cabinet matters, since hard surfaces can resonate and make a quiet system sound louder. Simple changes such as placing the NAS on a foam pad, an anti vibration mat or thick rubber feet will reduce the amount of vibration transferred into the furniture and can make a noticeable difference to perceived noise without changing the hardware.

The practical way to avoid this problem is to plan acoustics at the same time as you choose capacity and CPU. If the NAS must live in an occupied room, it makes sense to look at lower noise HDD lines, to avoid the very largest capacities where possible, and to consider using SATA SSDs for the working volume if budget allows. Checking vendor spec sheets for noise ratings in dB is useful, but you should also think about where the NAS will physically sit and how air can flow around it, since putting a box in a sealed cupboard simply forces the fans to run harder. Most modern NAS systems allow fan speed profiles and drive hibernation, which can reduce noise during idle periods, and many also support power schedules so the unit can power down completely during hours when it is not needed. You can also move heavy jobs such as RAID scrubs, indexing and backup windows into predictable time slots, for example overnight if the NAS is in a separate room, so that short periods of higher noise are less disruptive while the system remains quiet for normal daytime access.

Mistake #2: Ignoring Future Capacity and Expansion (PLAN AHEAD!)

A second common mistake is to buy a NAS that only matches your current data footprint with no realistic allowance for growth. Many first time buyers look at their existing files, see that they use 2TB or 4TB, then choose a 2 bay unit and a pair of modest drives that cover today with a small buffer. Once the NAS is in use, however, new cameras, phones and laptops start backing up to it, family members begin storing photos and videos, and it often becomes the default place for downloads and shared work files. Within a year or 2, the system that once looked spacious can be near its usable limit, especially once you take RAID overhead and snapshots into account.

The physical bay count and the way you populate those bays on day 1 has a direct impact on how easy it will be to grow later. A 2 bay NAS that starts fully populated leaves you with only a couple of options when you run out of room. You either replace both drives with larger ones, which is expensive and involves a full rebuild, or you bolt on an external expansion chassis if the vendor offers one. A 4 bay unit that initially uses only 2 drives gives you a much smoother path. You can add extra disks one at a time, or take advantage of flexible RAID schemes from some brands that allow mixing different drive sizes over time, which is far more forgiving when budgets are tight or upgrade windows are short.

Avoiding this mistake means planning capacity as a multi year decision rather than a single purchase. It is usually better to buy a slightly larger chassis with more bays than you think you need, then start with a sensible number of mid sized drives that offer a good cost per TB. This gives you headroom to add disks later without reorganising everything and lets the array performance improve as you add more spindles. It also leaves space for other changes such as introducing SSD volumes or cache in the future without having to retire the entire unit. In short, it is safer to overspec the enclosure a little and understuff it at the start than to buy the smallest possible model and discover that you have run out of practical expansion options far sooner than expected.

Mistake #3: Assuming SSD Cache and RAM Upgrades are a Magic Performance Fix (SAVE YOUR MONEY!)

New NAS owners often treat SSD cache and RAM upgrades as a universal answer to “my NAS feels slow”, without checking whether the underlying workload or hardware actually benefits. It is common to see a 2 or 4 bay system with a modest CPU and a couple of M.2 slots promoted heavily as “cache ready”, which encourages buyers to add SSDs and memory on day 1. In reality, if the processor is already running close to 100 percent under load, extra RAM will mostly sit idle and cache will only accelerate specific types of access. For simple sequential workloads such as bulk media streaming or large backup jobs, disk performance and network limits usually matter more than having faster cache in front of the array, so the investment does not translate into a noticeable improvement.

SSD cache in particular is often misunderstood. Write cache temporarily lands incoming data on SSDs and then flushes it to HDDs later, which can smooth out bursty writes but does not change the final speed of the array. Read cache keeps copies of frequently accessed “hot” data on SSDs, but in most NAS use this tends to be small random IO, metadata and thumbnails rather than entire large media files. Some platforms allow you to tune cache block size and policy, which can help in database or VM heavy environments, but for simple file sharing the benefit is limited. If a NAS mainly serves big video files to a handful of clients, using SSD cache rarely justifies the cost. In many cases, placing the NAS operating system, app data and indexes on an SSD volume, or using SSDs as a small primary pool for truly performance sensitive shares, delivers more predictable advantages than a generic cache layer.

The same caution applies to memory upgrades. More RAM allows the NAS to keep more filesystem cache and run more services concurrently, but it does not compensate for an underpowered CPU or a saturated network link. A basic check of CPU and memory utilisation under your typical workload is essential before buying additional modules. If CPU usage is consistently low while memory is pegged, extra RAM may help. If the processor is the bottleneck, adding memory or cache will not change the response time of apps and shares. For most first time buyers, it is more sensible to size CPU, network and base storage correctly first, then consider SSD based OS volumes, manual or automated tiering, and targeted RAM upgrades later if monitoring shows clear evidence that these changes will address a real bottleneck rather than an assumed one.

Note – If you are a QNAP NAS owner, you CAN use an alternative to ‘SSD Cache’, but using QTier – this MOVES (not copy) to data from slower HDDs and onto faster SSDs, as data is frequently accessed.

Mistake #4: Treating Power Consumption as an Afterthought (You Have CONTROL)

Many new NAS buyers focus on purchase price and capacity, then only think about power consumption after the first full month of electricity bills. A NAS is designed to be available around the clock, which means that even modest differences in idle draw add up over a year. Larger HDDs with more platters, multiple bays running full time, and older or less efficient CPUs all contribute to a steady baseline load, even when no one is actively using the system. In small flats or home offices this continuous draw can be a surprise, particularly for users coming from purely cloud based workflows where the power cost is hidden in the subscription fee.

Hardware choices have a direct impact on how much power a NAS will use at idle and under load. High capacity HDDs tend to have higher idle consumption because the mechanics must be ready to spin and seek immediately. A system with fewer, larger disks may draw more power at rest than a similar capacity built from several smaller drives, although this is not a strict rule and depends on the specific models. CPU generation and class matter as well. Modern low power x86 chips such as Intel N series parts can idle in the single digit watt range but still turbo high enough for typical home workloads, while older desktop class processors often draw more even when idle. Buyers who only look at drive capacity and bay count without checking HDD datasheets and CPU TDP figures can easily end up with a system that runs hotter and more power hungry than necessary for basic file serving and backups.

Software features and configuration also play a major role, yet many first time owners never touch these options after initial setup. Enabling HDD hibernation for lightly used volumes can drop disk consumption from around 8 to 12 W per drive to well under 1 W when idle, multiplied across several bays. Most NAS platforms support scheduled power on and power off, which allows you to shut the system down completely during hours when it is not needed and wake it automatically for work periods or backup windows. Moving heavy jobs such as backups, RAID scrubs and indexing into specific time slots also helps, since the system can stay in a lower power state for more of the day. Simple measures like these, applied on top of sensible hardware selection, make the difference between a NAS that quietly adds a manageable cost to your electricity bill and one that runs at full power far more often than your usage requires.

Mistake #5: Assuming Fewer Large Drives are Better (Often the REVERSE is Better)

A frequent assumption among new NAS buyers is that the best approach is to purchase the largest individual HDDs they can afford, fit a pair into a small enclosure and rely on that pair for both capacity and protection. On paper this looks simple and neat. Two 30TB drives in a 2 bay unit appear to offer an easy route to 30TB of usable space with RAID protection. However, this approach often produces a poor price per TB compared with building the same or greater capacity from several mid sized disks, and it concentrates a lot of risk and cost into each individual drive. When one of these large disks fails or needs replacing, the financial hit is substantial and rebuilds can be lengthy.

Cost of NAS Hard Drives (Example)
Seagate Ironwolf HDDs (Regular)	WD Red Pro HDDs (Pro Series)
1TB – $35 2TB – $65 4TB – $105 6TB – $158 8TB – $177 10TB – $224 12TB – $258 14TB – $271 16TB – $309 18TB – $389	4TB – $140 6TB – $173 8TB – $215 10TB – $245 12TB – $253 14TB – $270 16TB – $298 18TB – $349 20TB – $419 22TB – $551

In most cases, the price per terabyte on both sides will remain largely consistent at each capacity. HOWEVER, when you start putting these drives into a NAS/DAS enclosure and acting in the RAID configuration, it soon becomes apparent that the ben efits in Drive #s in a RAID 1 vs a RAID 5 immediately show a saving in almost every single capacity the smaller you go! Below are two examples of achieving 12TB in a NAS enclosure using RAID 1 vs using RAID 5 (so, still maintaining 1 disk drive failure protection and having 12TB of storage to use):

12TB Storage in a RAID 1 MIRROR	12TB Storage in a RAID 5

Looking at retail pricing makes the problem clear. Large capacity HDDs carry a significant premium that is not always reflected in proportional capacity gains. At the same time that a 30TB drive might cost 500 to 600 in local currency, 10TB or 12TB drives can often be found for less than 200 each. Four 12TB drives in RAID 5 or similar single disk fault tolerant layouts can deliver 36TB of usable space for less money than a pair of 30TB disks that only provide 30TB usable, while also offering more spindles for better aggregate performance. The trade off is higher drive count, which brings extra power use, more noise and additional points of failure, but in purely cost per TB terms the multi-drive configuration is often more efficient.

The practical lesson is that drive selection for a first NAS should consider more than headline capacity. New buyers should compare price per TB across several HDD sizes, factor in the desired RAID level and protection scheme, and understand how many drives their chassis can support now and in future. In many cases it is more effective to choose a slightly larger enclosure and populate it with several mid sized disks that offer a good value point, rather than filling a small unit with the largest drives available. This gives better flexibility for future expansion, more options if a disk fails, and a storage layout that balances cost, capacity and performance instead of relying entirely on a small number of very large and expensive disks.

Larger NAS/DAS systems are always more expensive, as they need to have more physical space, resource use in production and power/PSU sizes to run the larger enclosure. Add to this, thanks to memory shortages right now, that smaller scale NAS systems are starting to arrive with more memory by default (as 2-4GB is becoming less cost-effective to produce with chip shortages) and often with little/no increase in the base price. For example, below is the TS-264 and TS-464 NAS. Same CPU, design and ports – however the 2-Bay system has 8GB memory by default AND IS STILL $134 cheaper! So, this can often mean that you can save money on smaller quantities of larger capacity HDDs becuase the enclosure they are going in is cheaper over all.

Conclusion – PLAN AHEAD!

New NAS buyers rarely set out to make poor choices. The problems described above usually arise because a NAS is treated like a simple storage box rather than a device that will run all day, sit in shared spaces and gradually absorb more roles over several years. Noise, expansion, SSD cache, power consumption and drive sizing are all easy to overlook when you are comparing spec sheets or promotional bundles, yet each one has a direct and practical impact on how comfortable and economical the system will be to live with. The safest approach is to treat the first NAS purchase as a medium term infrastructure decision rather than a one off gadget. That means thinking realistically about where the box will sit, how many people will rely on it, how much data is likely to arrive over time and how much power draw and running cost is acceptable. A slightly quieter chassis, a few more bays, a balanced drive choice and sensible use of features like hibernation and scheduling will matter more in day to day use than chasing the biggest individual drives or adding SSD cache on day 1. By addressing these 5 areas before you buy, you reduce the risk of needing early upgrades or workarounds and increase the chance that the NAS you choose will remain suitable for several years without constant attention.

5 affordable Turnkey 10GbE NAS Solutions (Between $499 and $699)

For years, 10GbE networking has been seen as a premium feature reserved for high-end or enterprise-grade NAS devices, often pushing total system costs well beyond the reach of home users and small businesses. However, as controller prices have dropped and demand for faster data transfers has grown, a new wave of affordable NAS solutions has started to appear with built-in 10GbE. These systems no longer require expensive proprietary upgrade cards or third-party NICs, and many sit comfortably below the $699 / £599 price point. They cover a range of use cases, from compact SSD-based NAS devices to rackmount storage appliances and versatile desktop units. Below is a selection of some of the most notable options currently available, each offering a balance of performance, connectivity, and affordability for users who want to move beyond 1GbE or 2.5GbE without breaking the bank.

UniFi UNAS Pro (7-Bay, Rackmount)

I keep coming back to two words for the UniFi UNAS Pro—fundamentals and consistency. UniFi has clearly focused on making this system a strong addition to their ecosystem, prioritizing the essential storage needs of a NAS. They’ve succeeded in this, but comparisons with long-established competitors are inevitable. While solid, reliable, and stable, the UniFi UNAS Pro will take time to be competitive on the software front. If you’re deeply invested in the UniFi ecosystem, you’ll appreciate its ease of use and integration. However, outside of a UniFi network, it may feel feature-light compared to alternatives. The pricing is competitive for a launch product at $499, and while it’s not the best NAS on the market, it’s the most user-friendly and UniFi-ready. It will likely satisfy many users’ needs. I can certainly see this being integrated into existing UniFi networks as a 2nd stage backup alongside their already existing 3rd party NAS solution, with the potential to graduating to their primary storage as Ubiquiti continue to evolve this platform above and beyond the fundamentals their have nailed down in the UNAS Pro system.

• Approx. Price: $499 / £400

• Specs: ARM Cortex-A57 quad-core CPU, 8 GB RAM, seven 2.5″/3.5″ SATA bays, 1×10GbE SFP+ and 1×1GbE.

• Why It Stands Out: Exceptional price-to-performance for pure storage needs. Lacks advanced multimedia or container apps but ideal for high-speed backups in a rackmount setup.

UGREEN NASync DXP4800 Plus

BOTTOM LINE – The UGREEN NASYnc DXP4800 Plus does not feel ‘finished’ yet and still needs more time in the over, but UGREEN have been very clear with me that this product is not intended for release and fulfilment till summer 2024 and improvements, optimization and product completion is still in progress. Judging the UGREEN NAS systems, when what we have is a pre-release and pre-crowdfunding sample, was always going to be tough. The DXP4800 PLUS is a very well put-together NAS solution, arriving with a fantastic launching price point (arguably even at its RRP for the hardware on offer). UGREEN has clearly made efforts here to carve out their own style, adding their own aesthetic to the traditional 4-bay server box design that plagues NAS boxes at this scale. Equally, although they are not the first brand to consider Kickstarter/Crowdfunding for launching a new product in the NAS/personal-cloud sector, this is easily one of the most confident entries I have seen yet. The fact that this system arrives on the market primarily as a crowdfunded solution (though almost certainly, if successful, will roll out at traditional retail) is definitely going to give users some pause for thought. Equally, the UGREEN NAS software, still in beta at the time of writing, although very responsive and nailing down the basics, still feels like it needs more work to compete with the bigger boys at Synology and QNAP. Hardware architecture, scalability, and performance are all pretty impressive, though the performance of the Gen 4×4 M.2 NVMe slots didn’t seem to hit the numbers I was expecting. Perhaps a question of PCIe bottlenecking internally, or a need for further tweaking and optimization as the system continues development. Bottom line, with expected software updates to roll out closer to launch and fulfillment, such as an expanded App center and mobile client, the UGREEN DXP4800 Plus is definitely a device worth keeping an eye on in the growing Turnkey and semi-DIY NAS market. As an alternative to public cloud services, this is a no-brainer and worth the entry price point. As an alternative to established Turnkey NAS Solutions, we will hold off judgment till it is publicly released.

• Approx. Price: $595 / £475

• Specs: Intel Pentium Gold 8505 (6-thread), 8 GB DDR5, 4×SATA + 2×M.2 slots, 1×10GbE and 1×2.5GbE, plus HDMI, USB-C, USB-A, and SD reader.

• Why It’s Attractive: Well-rounded design with rich connectivity and media support, undercuts most rivals on price and features.

Who Are IceWhale, Is ZimaOS a Legitimate NAS Software Player, and Are They Ready? An Interview with Lauren Pan, IceWhale CEO

IceWhale is one of the youngest companies in the self-hosting space, yet its operating system, ZimaOS, has rapidly become one of the most discussed alternatives to established NAS platforms. Built on an immutable Linux foundation with a strong emphasis on user experience, ZimaOS aims to combine the approachability of turnkey systems with the flexibility of DIY hardware. Behind that vision is Lauren Pan, the founder and CEO of IceWhale, whose team previously created CasaOS and later shifted focus to a more scalable and controlled platform in ZimaOS. Now that the brand has begun it’s roll out of it’s $29 lifetime license, it has now become apparent that this plucky start up needs to be taken alot more seriously, as well as be weighed critically in the same way other long-established NAS software platforms are.

So, during a recent visit to Shenzhen, I sat down with Lauren for an extended conversation about the origins of ZimaOS, the challenges of building a modern NAS operating system, the company’s rapid growth, and how the wider NAS industry is being reshaped by new players, security expectations, and AI-driven workloads. This interview captures his perspective on product design, community involvement, security, the evolution of the market, and IceWhale’s long-term ambition to bring personal servers into everyday households.

When you began building the operating system back in 2021 with a very small founding team, what were those early days like and what were you aiming to create?

In 2021 the early team was only four members. I found our final CTO at that time, and we started to build the official design. At the beginning we were passionate and wanted to build a comprehensive, robust and customizable operating system for home lab users and tech-savvy people. But after three months, when we reviewed our progress, it was terrible. Even in the early stages you could tell there was something there because it was so light. That lightness was the biggest appeal for many people.  If you didn’t know what you were doing it was a great gateway into experimentation and learning. For people who did know what they were doing, the lightweight design made it flexible. In the first three months we honestly didn’t know exactly what we were building. We pivoted fast. We spent about a month researching Reddit, watching community videos including yours, and we realised people needed a lightweight, easy-to-use command line to set up a home server. That’s where the idea for CasaOS came from.

Fast-growing and successful products come from very sharp product insight. After that insight, the next phase is delivering high quality and building a good reputation through community feedback. This is core to our product methodology.
When we target a feature or user value, we don’t immediately invest heavy development resources. Instead, we speak with community members, moderators, and creators like you. We learn, and listen to how you see things, and watch user experience live on screen.

---

How big is the IceWhale team today?

Right now we have 35 members. Recently, because ZimaOS has been growing so fast, the operational pressure is high. Our downloads and user base are increasing quickly. So in the coming months we plan to expand the team to around 50 people. The purpose is to continue delivering high-quality support to the community. Our download numbers and user base are growing very fast, and that creates a lot of operational pressure. That is why we are expanding the team significantly. Supporting the community with high-quality responses is one of our top priorities, and growth in the next few months is focused on providing that support.

---

Why create ZimaOS when CasaOS already existed?

There are two main reasons. First, product direction. CasaOS is very open and we maintained it for more than two years with no license and free global access. However, as the process continued, we gradually realized that relying solely on the existing system architecture could no longer fully meet future requirements in terms of performance, scalability, and stability.. After deep internal discussion, we decided to build the OS from scratch rather than using Debian or mergerFS. This way, we can fully control quality and stability at the infrastructure layer. In 2023 we studied Home Assistant, Raspbian, and best practices in Linux. We built ZimaOS from the buildroot foundation, choosing our own kernel packages and implementing an immutable design. Users cannot modify system files because we focus on stability for daily use. But since many users still want to tinker, we layered Docker Compose on top.

Second, business sustainability. CasaOS used Apache 2.0 licensing because at that time no Chinese company was building a home server OS. We benefited hugely from open-source, so we needed to give back. But some companies began using CasaOS to build their own commercial products. To create a sustainable business cycle we needed a platform we could fully control, and that became ZimaOS.

What is IceWhale doing to handle vulnerabilities responsibly?

We rely on GitHub and created a CVE reporting program. We announced it to the community, and anyone can report security issues. Internally, our development team handles these reports through a structured process. Every Monday we review all community feedback, including security issues, reliability problems, and feature requests. In the last two weeks, especially after your video, installations increased rapidly and so did feedback.

---

Would you consider a security bounty program?

We are considering it. We need to strengthen our internal capabilities first. Bounty programs can attract both ethical hackers and opportunistic users, but they also help prevent widespread damage. Also, we are still very early into our funding sustainability to commit to something this large.

---

A lot of people were surprised that ZimaOS is only 29 dollars for a lifetime license. How did you arrive at that price?

The pricing comes from the founding team’s expectations about the market. The NAS industry is still mostly limited to tech-savvy users, but we see a different future. We believe that in the next ten years everyone will have a personal or home server for daily use, home automation, and personal agents. If you evaluate the current NAS market at around one million users, then pricing at 300 dollars, like some competitors, makes sense because their investment is huge. But if you believe the market will grow far beyond that small base, then pricing it at 29 dollars makes much more sense. We think the market will not remain limited to only a few million users.

---

Crowdfunding from companies like UGREEN has shown how quickly the market can shift when a new player enters the market. Do you think that changed industry expectations towards Chinese products?

UGREEN is a great example. Before their launch I spoke with people at several major brands and many were not worried. They thought UGREEN had no experience and would go nowhere. Then they raised 6.5 million dollars and sold 12,000 units. That was a lot of market share disappearing very quickly. This has really opened the door to a shake-up of private server ownership. In videos, you’ve often talk about control, flexibility, and personal ownership of data. This is core to the philosophical foundation for ZimaOS. When people want to host something themselves, they need full control. I don’t want users to be limited by a specific brand. They should decide how to manage their data, how to customise their apps and services, and how to extend computing power with GPU or 10 GbE. That purpose is at the core of ZimaOS.

We learned from the community that people need flexibility. At the same time, learning technical skills is still hard, so we also provide complete products like ZimaBoard and ZimaCube. This means users can get started quickly if they want an out the box solution. The industry is changing. Traditional NAS brands may move into higher tiers and ignore the bottom tier. New players will reshape the value and mid-range segments. The market will expand, but many brands are not ready for rapid shifts like AI integration.

---

Would you consider adding surveillance features to ZimaOS?

Not yet. The surveillance market is very large and specialised. Right now we are focused on building a reliable core operating system.

---

Some New and Entry level users find the USB installation process or migration away from an existing NAS to ZimaOS the only difficult steps. How do you plan to address that? Would you consider pre-bootloader-ready USB sticks for retail? Or specific Synology-to-ZimaOS migration tool?

I agree. Installation is still the biggest barrier for beginners. We are considering better solutions, including pre-prepared media, streamlined installation tools, and future hardware that removes the need for external installation completely. Making that first step easier is important. The idea of a installation-ready official USB with the license ready loaded makes alot of sense, and definitely something we can consider and explore, thank you. With branded migration tools, that is another very good idea. Migration is one of the biggest concerns for users switching from turnkey NAS systems. A dedicated migration tool could completely open the door for them. We should do that.

---

Will CasaOS be retired any time soon?

No. We consider CasaOS our LTS version. We will continue fixing bugs and maintaining it. There is no CasaOS 2.0 planned at the moment. Its main advantage is ARM compatibility, which few other NAS operating systems support.

---

Will there be a new ZimaCube?

Yes. In the next three months we will upgrade ZimaCube to the M2 version and announce it soon. It’s an improvement, not ZimaCube 2.0, more like a plus model. It will replace the existing version entirely. The positioning of ZimaCube was right, but I don’t think we made the first generation good enough to compete with new market entrees. So we focused heavily on improving the details while keeping the price. However, ZimaCube priced between 600 and 1200 dollars is still too expensive for the broader market and entry level, so we are investigating internally a product called “Zima Mini” to target the two-bay and four-bay market. More on that in 2026.

---

Where do you want IceWhale and ZimaOS to be in five years?

Our vision is to serve more than 400 million households and bring a personal or home server to every family. In five years we want IceWhale to be positioned clearly as an operating system company rather than a hardware company. That has become very clear in the last two years.

---

What moment made you most proud in the IceWhale journey?

There was a moment two years ago, when CasaOS reached around ten thousand community members. In China many people don’t care much about privacy or self-hosting, so when I told local investors that I wanted to build a NAS and open-source OS, they didn’t understand why. They thought we didn’t need it. But when the GitHub project took off, when the Discord community grew, and when users started creating mods without ever speaking to us, I realised they understood exactly what we were building. They understood the vision even though I never explained it publicly. That moment validated everything. It reminded me why I founded the company.

fnOS Beta Review – Should You Keep an eye on Feiniu NAS OS?

Feiniu Private Cloud, better known by its system name fnOS, is a closed-source Chinese NAS operating system currently in public beta. Developed by a small team of self-described NAS enthusiasts, fnOS is marketed as a “genuinely free” NAS solution for domestic users in China and is designed to run on standard x86 PC and NAS hardware. It offers media management tools, AI-powered photo categorization, Docker container support, RAID configurations, and an app ecosystem — all within a graphical user interface that resembles several other recent Chinese NAS solutions. The system is rooted in a Debian-based Linux distribution and aims to provide plug-and-play functionality for users seeking an alternative to more established platforms like DSM, QTS, or TrueNAS.

However, fnOS arrives with notable caveats. As a closed-source system with minimal public documentation, there is currently no way to verify its internal processes, telemetry behaviour, or long-term data integrity protections. Moreover, its security architecture lacks advanced features like two-factor authentication, iSCSi, ZFS or hardened remote access protocols that have fast become an industry standard of many other NAS software options in the market.

Language support outside of Simplified Chinese is also not fully implemented, creating potential navigation barriers for international users. While the interface and features may seem appealing on the surface, fnOS is still in a formative stage — and with it come the usual risks of data loss, unpatched vulnerabilities, and limited user support. As this review will show, fnOS represents a curious blend of innovation, imitation, and potential. But its closed nature, beta status, and regionally restricted development raise several questions about its readiness for use beyond a testing environment.

Disclaimer for Users Considering fnOS Right Now

Anyone considering the use of Feiniu Private Cloud (fnOS) should do so with full awareness of the risks inherent in testing an early-stage, closed-source operating system. Although the software is being actively developed and presents a relatively complete GUI with numerous features, it remains in public beta. The system has not yet undergone broad public scrutiny, independent code audits, or transparent vulnerability testing, making its real-world reliability uncertain. The developers themselves have issued formal cautions, explicitly stating that the beta version may cause system crashes, compatibility problems, or data loss. Users should avoid deploying fnOS on primary NAS systems, in business environments, or on any hardware storing valuable or irreplaceable data. Thorough offline backups should be made prior to installation, and any testing should be performed in a non-critical sandbox environment. The system’s UI is currently presented almost entirely in Simplified Chinese, with no comprehensive English language support available at this stage. Translation tools such as Google Lens or Microsoft Edge’s built-in translation functions may offer partial usability, but navigation and configuration still present challenges for non-Chinese speakers.

Security considerations are especially important. fnOS lacks industry-standard safeguards such as two-factor authentication, secure portal client tools, and deeper role-based access controls. There is also no detailed public disclosure about how the system handles network traffic, cloud synchronization, or metadata collection, which is a point of concern given its integration with AI services and remote access features. At present, it is unclear whether any telemetry or user analytics are sent back to the developers, and the absence of source code prevents community verification. In summary, fnOS should be treated as experimental software. While it may offer a glimpse into emerging trends in the Chinese NAS market and present intriguing ideas around media organization and local AI integration, users must approach it with caution and a strong understanding of the security and stability limitations that accompany early-stage, proprietary platforms.

Design and UI

The user interface of fnOS is visually structured and attempts to emulate the layout seen in many modern NAS operating systems, with clear menu segmentation and app-like modularity. Upon installation, users are presented with a desktop-style environment that includes access to system configuration, storage management, multimedia tools, and containerized applications.

Navigation is conducted through a web browser, and the interface features icon-driven panels that mirror the design language of platforms like DSM (Synology) or QTS (QNAP), albeit with some localization quirks. Despite its early-stage development, the UI demonstrates a coherent structure that is functional, if not yet polished.

However, the current implementation suffers from language accessibility issues. The interface is only available in Simplified Chinese, and efforts to translate the interface using automated tools like Google Translate are mostly ineffective, as it relies on dynamic rendering elements that these tools cannot parse. Microsoft Edge’s translation feature performs better but still results in fragmented grammar and partially translated system prompts. This creates a substantial usability barrier for non-Chinese speakers, particularly when trying to configure advanced settings such as RAID arrays, user permissions, or application environments.

In terms of responsiveness and performance, the UI behaves relatively smoothly even on modest hardware. Common actions such as creating storage volumes, configuring shares, or launching apps execute without visible lag. While some buttons and system prompts may feel incomplete or imprecise due to beta status, core layout principles like logical menu placement and centralized settings are well applied. The overall experience suggests that while fnOS is clearly designed with user convenience in mind, it is not yet refined enough for a wide international audience.

Services and Features

fnOS provides a wide array of features targeting home media consumption, local data storage, and remote accessibility. One of its most promoted capabilities is its media handling, with built-in applications for organizing video, music, and photos. The system includes automatic metadata scraping for movies and TV shows, AI-driven facial and object recognition for photo libraries, and a basic music playback utility.

These media apps mimic the functionality of solutions like Plex or Jellyfin, offering poster walls, subtitle downloads, and transcoding options. However, it should be noted that many of the multimedia tools are proprietary adaptations or containers wrapping existing open-source tools rather than purpose-built innovations.

The system also integrates AI-driven services at the local level. The photo application includes features like character-based photo aggregation and image search via text input. Users can select from multiple AI models depending on resource availability and desired recognition accuracy, though it’s not entirely clear whether these models run exclusively offline or leverage external processing. While the integration appears functional, it is not yet well-documented, and the practical use cases are still limited by the interface’s language barriers and overall beta stability.

fnOS includes standard NAS features such as RAID configuration (supporting levels like RAID 0, 1, and 5), SSD caching, and storage expansion. It uses BTRFS or EXT4 as file system options, with support for snapshot creation on BTRFS volumes. Network protocols such as SMB3, NFS, FTP, and WebDAV are available, with multi-channel SMB enabled by default.

There is also a built-in file manager allowing basic copy, move, download, and sharing functions, including time-limited and password-protected links. While ZFS is not supported, the storage tools provided are sufficient for basic to intermediate users familiar with RAID and shared folder management.

The included App Center is container-based and supports various community and utility applications. Notable entries include Qbittorrent, Jellyfin, Transmission, Alist, Portainer, and Chromium, alongside more region-specific tools like 115 Network Disk and Baidu Cloud integration.

The application store largely reflects popular Dockerized solutions and offers minimal documentation on integration specifics. fnOS also includes a rudimentary virtual machine manager, which allows for Windows VM creation via ISO files, though functionality is basic.

Backup tools support both local folder sync and remote NAS replication, but third-party cloud sync is limited in scope and likely tied to domestic Chinese services.

 

Pros and Cons of fnOS?

One of the most notable strengths of fnOS is its broad feature coverage for a beta-stage NAS operating system. Despite being early in its development, it includes many of the core functions expected from a modern NAS platform: multi-tiered RAID support, snapshot capabilities (via BTRFS), Docker-based application hosting, multimedia indexing, and even virtual machine support.

For home users interested in media storage, the built-in tools for automatic metadata scraping and subtitle acquisition, combined with basic transcoding support, make it a practical solution for centralized media access — particularly when paired with a TV interface or mobile app.

The inclusion of AI-powered image recognition and customizable AI models in the photo management application is another area where fnOS differentiates itself. Users can configure local facial and object recognition models to assist in organizing large photo libraries, and even perform text-based image searches. While this isn’t entirely unique in the NAS market, the ability to select from different AI models and the implementation of geolocation tagging and facial clustering demonstrates that the development team is thinking beyond basic storage functionality. It suggests potential for future expansion into smart content management if development continues at pace.

However, fnOS also presents several clear drawbacks. Security remains underdeveloped, with no support for two-factor authentication, no publicly available information on encryption practices, and limited visibility into how data is handled or transmitted over the network.

While SSL certificates and basic firewall tools are present, the absence of fine-grained user permission structures or auditing functionality makes it unsuitable for multi-user environments or deployments where data privacy is a primary concern. Additionally, remote access services built into fnOS are proprietary and undocumented, which raises further questions for users concerned about trust and control over their network.

Another key limitation is the lack of proper language support and international readiness. At the time of writing, the UI is only available in Simplified Chinese, and the developers have not confirmed a timeline for multilingual support, also highlighting that this will be phased into a paid/commercial use version. This, combined with limited documentation and forum discussion outside of Chinese-speaking communities, makes troubleshooting and adoption by non-Chinese users significantly more difficult. Moreover, as a closed-source system, fnOS cannot benefit from the auditing, forking, and community patching practices that open-source NAS platforms rely on to maintain user trust and long-term sustainability.

Conclusion and Verdict of fnOS NAS Software

fnOS represents an ambitious attempt to build a full-featured, home-friendly NAS operating system from the ground up, targeting a domestic Chinese audience first and foremost. Its functionality is surprisingly broad for a beta, covering storage management, AI-powered media organization, Docker app deployment, and local VM hosting. However, its closed-source nature, limited language support, and undeveloped security framework make it unsuitable for deployment outside controlled test environments. For users within China who are technically confident, aware of the risks, and seeking a free, self-managed solution, fnOS may have appeal. For international users, particularly those prioritizing transparency, privacy, or robust security, fnOS remains a curiosity—not yet a contender.
