Vous avez des dossiers sensibles que vous aimeriez chiffrer avant de les balancer sur un cloud ou un disque externe ? Ça tombe bien, je vous ai trouvé un petit outil en Rust qui va vous plaire.
Obsidenc, c'est son nom, est un utilitaire de chiffrement que son créateur qualifie de "paranoid-grade". Et après avoir jeté un œil au code source, je peux vous dire que c'est pas du marketing puisque ce truc archive votre répertoire en TAR et le chiffre avec XChaCha20-Poly1305, un
algorithme AEAD
moderne qui assure à la fois la confidentialité et l'intégrité de vos données.
Côté dérivation de clé, ça utilise Argon2id conforme à la RFC 9106. Pour les non-initiés, Argon2id c'est l'algo qui a gagné le Password Hashing Competition et qui est spécifiquement conçu pour résister aux attaques par GPU et circuits spécialisés (ASIC). L'outil adapte automatiquement les paramètres à votre machine en utilisant 85% de votre RAM disponible (entre 512 Mo minimum et 2 Go maximum) afin de rendre le brute-force astronomiquement coûteux. Et si vous avez moins de RAM dispo, il compense en augmentant le nombre d'itérations.
C'est du code Rust bien propre qui utilise les bibliothèques cryptographiques RustCrypto (bien auditées par la communauté) et le code implémente des bonnes pratiques de sécurité comme le memory locking (mlock sur Unix, VirtualLock sur Windows) pour éviter que vos clés se retrouvent dans le swap, et le
zeroize
pour effacer la mémoire sensible après utilisation.
Vous compilez ça avec cargo build --release, puis pour chiffrer un dossier :
Le mot de passe doit faire minimum 20 caractères (pas de négociation possible, déso pas déso) et vous devez le confirmer deux fois. Vous pouvez aussi ajouter un fichier de clé en plus du mot de passe pour du 2FA old-school.
L'outil a aussi quelques protections défensives sympas. Par exemple, il refuse les symlinks (vecteur d'attaque classique), limite le nombre de fichiers à 1 million et la longueur des chemins à 4096 caractères pour éviter les zip bombs. Sur les systèmes Unix, il vérifie même que votre fichier de clé n'est pas lisible par tout le monde (chmod 600 obligatoire).
Cet outil part du principe qu'un attaquant peut avoir accès à votre fichier chiffré et dispose de temps illimité pour tenter de le casser, du coup, tout est conçu pour rendre l'attaque offline la plus douloureuse possible.
Bref, si vous cherchez un moyen de sauvegarder vos dossiers sensibles de manière vraiment sécurisée avant de les balancer sur un cloud ou un disque externe,

Network attached storage in 2025 has shifted from being a niche utility to a central part of how many homes, studios and small businesses manage data. Rising storage needs, more capable low power CPUs and a renewed interest in self hosted services have produced a wave of compact, power efficient systems alongside more traditional multi bay enclosures. This article identifies a small group of NAS devices that stood out during 2025 for their hardware design, price-to-performance balance or the specific problems they address, rather than for brand familiarity alone. To qualify for inclusion, a NAS had to be commercially available for general sale during 2025, not an older carry over model or a crowdfunded prototype. No Kickstarter, Indiegogo or pre production units were considered, and devices that only existed as region locked or short lived batches were excluded where availability could not be reasonably confirmed. Both turnkey systems with bundled NAS operating systems and OS agnostic, barebones style hardware are included, provided they offer a clear proposition for real world use in home lab, small business or mobile workflows.
Honourary Mention – The UniFi UNAS Series – $199 to $799
SPECS: Quad core ARM Cortex A55 or A57 at 1.7 to 2.0 GHz – 4 to 16 GB LPDDR4 – 2 to 8 x 3.5″ SATA bays – 1 x 2.5 GbE RJ45 / 1 x 1 GbE RJ45 / up to 3 x 10 GbE (RJ45 and SFP+) – 0 or 2 x M.2 NVMe SSD slots for cache (depending on model).
While not a single flagship unit, UniFi’s expanded UNAS NAS range in 2025 merits an honorary mention as a platform level development. Moving from a single NAS offering in 2024 to multiple UNAS models in 2025, UniFi shifted from dabbling in storage to positioning itself as a serious option for small business, UniFi centric home labs and integrators that want storage tightly aligned with existing UniFi networking and management.
The significance here is not an isolated specification or feature, but the fact that a major networking vendor is rapidly building out a NAS portfolio at a time when private data ownership, self hosted services and integrated stacks are becoming more important, adding competitive pressure on more established, slower moving NAS brands.
SPECS: AMD Ryzen 7 Pro 8845HS – up to 128 GB DDR5 ECC via 2 SODIMM slots – 6 x 3.5″/2.5″ SATA bays – 2 x 2.5 GbE RJ45 / 2 x 10 GbE SFP+ – 5 x M.2 2280 NVMe PCIe 4.0 slots.
The Aoostar WTR Max is a prebuilt, OS agnostic NAS chassis that stands out for its hardware density at its price point. It combines 6x hard drive bays with 4x M.2 NVMe slots, dual 10 GbE networking and an AMD server grade platform with ECC memory support in a compact enclosure that has been noted for effective cooling relative to its size. Rather than tying buyers to a proprietary operating system, it is intended to run third party NAS or server platforms, which gives it flexibility but also means any software integration and management experience depends on the OS the user chooses to deploy. Throughout 2025 it has frequently been in short supply, indicating sustained demand from home lab users and small operators who want near turnkey hardware with specifications that would be expensive to replicate via a fully DIY build.
What We Said in our June ’25 review HERE: The Aoostar WTR Max stands out as a rare blend of high storage density, advanced connectivity, and raw compute performance in a compact NAS form factor, making it well-suited for experienced users seeking a versatile, self-managed platform. With support for up to 11 drives—six SATA and five NVMe Gen 4—paired with an enterprise-grade Ryzen 7 PRO 8845HS CPU and ECC memory compatibility, the system offers workstation-class capabilities for storage-heavy workflows, including virtualization, multimedia processing, and hybrid file serving. Dual 10GbE SFP+ and dual 2.5GbE ports provide ample bandwidth for multi-user access or isolated subnet roles, while the OCuLink interface enables high-speed external expansion, compensating for the absence of a traditional PCIe slot. Additional benefits like a fully customizable LCD status display, low fan noise, and consistently low thermals under load reinforce the system’s value in 24/7 deployments.
However, the WTR Max does present some caveats—namely, internal NVMe cross-performance appears constrained by shared bandwidth, and the lack of an internal PCIe slot could be limiting for users requiring more conventional upgrade paths. The LCD panel’s configuration software also proved cumbersome, raising security flags and requiring manual IP client setup, which may deter less technically inclined users. Lastly, the use of an external 280W PSU—while effective—won’t appeal to those expecting internal power integration in a workstation-style chassis. Nonetheless, for users who value full control over their NAS stack and want to avoid restrictive ecosystems, the WTR Max delivers a rare combination of hardware freedom and scalability that few turnkey systems offer in this price and size category.

CONS
Limited Internal NVMe Cross-Throughput Inter-M.2 transfer speeds are capped (~500–600 MB/s), possibly due to shared chipset lanes or controller design. No Internal PCIe Slot Expansion is limited to OCuLink; users needing traditional PCIe cards (e.g., GPUs or HBAs) may find this restrictive. LCD Panel Software Can Be Problematic Configuration software raised browser security flags and requires static IP client setup, making it less accessible. External Power Brick Only 280W external PSU is functional but not ideal for rackmount or integrated enclosures; some users may prefer internal ATX power.
SPECS: AMD Ryzen 7 255 or AMD Ryzen AI 9 HX Pro 370 – up to 96 GB DDR5 (ECC on N5 Pro) – 5 x 3.5″/2.5″ SATA bays – 1 x 5 GbE RJ45 / 1 x 10 GbE RJ45 – 3 x M.2 NVMe slots (2 convertible to U.2, PCIe 4.0).
The Minisforum N5 is a compact 5-bay NAS that targets users who want preconfigured hardware with some workstation derived design features. It uses an x86 CPU in the same general class as the Aoostar WTR Max, paired with an internal storage module of 64 GB for the system volume, and is typically sold in the 599 to 699 USD range, with the separate Pro variant occupying a higher bracket. The chassis integrates a removable drive base section for easier maintenance, and the platform includes multi-gig networking up to 10 GbE and 5 GbE, a PCIe expansion slot and USB4 connectivity for additional bandwidth or external devices. Minisforum ships the N5 with its own NAS operating system to provide an immediate out of box experience, but the software is still relatively young and many buyers elect to overwrite the included module with a more established NAS or server OS. Throughout 2025, availability has been intermittent, reflecting a level of demand from home lab users who want higher specification NAS hardware without building entirely from individual components.
The Minisforum N5 Pro is an impressive and highly versatile NAS platform that successfully combines the core strengths of a storage appliance with the capabilities of a compact, workstation-class server, making it suitable for demanding and varied use cases. Its defining features include a 12-core Ryzen AI 9 HX PRO 370 CPU with 24 threads and onboard AI acceleration up to 50 TOPS, support for up to 96GB of ECC-capable DDR5 memory for data integrity, and a hybrid storage architecture offering up to 144TB total capacity through a mix of five SATA bays and three NVMe/U.2 slots. Additional highlights such as ZFS file system support with snapshots, inline compression, and self-healing, along with high-speed networking via dual 10GbE and 5GbE ports, and expansion through PCIe Gen 4 ×16 and OCuLink interfaces, position it well beyond the capabilities of typical consumer NAS systems. The compact, fully metal chassis is easy to service and efficiently cooled, enabling continuous operation even under sustained virtual machine, AI, or media workloads.
At the same time, the bundled MinisCloud OS, while feature-rich with AI photo indexing, Docker support, and mobile integration, remains a work in progress, lacking some enterprise-grade polish, robust localization, and more advanced tools expected in mature NAS ecosystems. Minor drawbacks such as the external PSU, the thermally challenged pre-installed OS SSD, and the higher cost of the Pro variant relative to the standard N5 are important to weigh, particularly for users who may not fully utilize the Pro’s ECC and AI-specific advantages. For advanced users, homelab builders, and technical teams who require high compute density, flexible storage, and full control over their software stack, the N5 Pro delivers workstation-level performance and configurability in NAS form—offering one of the most forward-thinking and adaptable solutions available today in this segment.
High-performance AMD Ryzen AI 9 HX PRO 370 CPU with 12 cores, 24 threads, and AI acceleration (50 TOPS NPU) is INCREDIBLE for a compact desktop purchase Support for up to 96GB DDR5 memory with ECC, ensuring data integrity and stability in critical environments ZFS-ready storage with numerous ZFS and TRADITIONAL RAID configurations, snapshots, and inline compression Hybrid storage support: five 3.5\\\"/2.5\\\" SATA bays plus three NVMe/U.2 SSD slots, with up to 144TB total capacity Versatile expansion options including PCIe Gen 4 ×16 slot (×4 electrical) and OCuLink port for GPUs or NVMe cages Dual high-speed networking: 10GbE and 5GbE RJ45 ports with link aggregation support + (using the inclusive MinisCloud OS) the use of the USB4 ports for direct PC/Mac connection! Fully metal, compact, and serviceable chassis with thoughtful cooling and accessible internal layout - makes maintenance, upgrades and troubleshooting a complete breeze! Compatibility with third-party OSes (TrueNAS, Unraid, Linux) without voiding warranty, offering flexibility for advanced users
CONS
MinisCloud OS is functional but immature, with unfinished localisation and limited advanced enterprise features - lacks MFA, iSCSI, Security Scanner and More. Nails several key fundamentals, but still feels unfinished at this time. Despite External PSU design (will already annoy some users), it generates a lot of additional heat and may not appeal to all users overall Preinstalled 64GB OS SSD runs hot under sustained use and lacks dedicated cooling. Plus, losing one of the 3 m.2 slots to it will not please everyone (most brands manage to find a way to apply an eMMC into the board more directly, or use a USB bootloader option as a gateway for their OS Premium $1000+ pricing may be hard to justify for users who don’t need ECC memory or AI capabilities compared to the standard N5 at $500+
SPECS: Intel N150 quad core Twin Lake SoC up to 3.6 GHz – 12 GB LPDDR5 (with 16 GB LPDDR5 variant announced) – 6 x M.2 2280 SSD bays – dual 2.5 GbE RJ45 / WiFi 6 – 6 x M.2 NVMe PCIe 3.0 slots (5 x1 / 1 x2, one slot also supporting SATA SSD).
The Beelink ME Mini N150 is an all flash, ultra compact NAS style platform built around 6x M.2 NVMe bays, an Intel N150 CPU and 12 to 16 GB of memory, aimed at low power home lab and edge storage roles. It typically ships in the 200 to 250 USD bracket depending on retailer and configuration, and includes a small amount of onboard eMMC storage intended for the operating system, with users commonly installing Linux distributions such as Ubuntu or other lightweight NAS platforms. Connectivity includes dual 2.5 GbE ports, making it suitable for multi gig networks despite its size, and its idle power draw with all slots populated has been measured in the sub 10 to 12 W range, which positions it as an efficient always on node. While comparable N150 based systems from GMKTEC and turnkey brands like TerraMaster arrived in the same period, the ME Mini gained wider attention in 2025 because its combination of price, power envelope and density is difficult to match via a conventional DIY build using standard motherboards and cases.
The Beelink ME Mini NAS delivers an uncommon blend of size, functionality, and efficiency in a market segment often dominated by larger, louder, and less integrated alternatives. It is not designed to compete with traditional enterprise-grade NAS devices or modular, scalable solutions for prosumers. Instead, its strengths lie in targeting the needs of home users who want a quiet, energy-efficient storage solution that is easy to deploy, aesthetically unobtrusive, and capable of handling daily tasks such as media streaming, file backup, or soft routing. The inclusion of six M.2 NVMe SSD slots—paired with a Gen 3 x2 system slot—offers a rare level of expansion in such a small enclosure. The integration of an internal PSU, silent fan-assisted cooling, and a surprisingly effective thermal design are thoughtful touches that differentiate it from the majority of DIY NAS mini PCs.
That said, it is not without limitations. The memory is non-upgradable, thermal accumulation at the base suggests room for improvement, and bandwidth ceilings imposed by Gen 3 x1 lanes will constrain users who demand high parallel throughput. Still, for its price point—particularly when pre-order discounts are applied—the ME Mini offers significant value, especially when compared to ARM-based NAS solutions with similar or lower specifications. With bundled Crucial SSD options and support for a wide range of NAS operating systems, it positions itself as a ready-to-go platform for tech-savvy users wanting to avoid the assembly of a fully DIY system. Overall, while not a product for every use case, the Beelink ME Mini succeeds in its aim to be a compact, stylish, and capable home NAS.

SPECS: Intel N100 quad core up to 3.4 GHz – 16 GB LPDDR5 – 2 x 2.5″ SATA bays / 4 x M.2 NVMe bays (total 6 bays) – 1 x 10 GbE RJ45 – 4 x M.2 2280 NVMe SSD slots.
The Lincstation N2 is a compact prebuilt NAS positioned primarily on value, combining an Intel N100 quad core CPU, 16 GB of non upgradable memory and 10 GbE networking in a small chassis. Storage is split between 4x M.2 NVMe bays and 2x 2.5 inch SATA bays, giving a mix of high speed solid state and more conventional, higher capacity drives, with visible status LEDs on the exterior. Typical street pricing in 2025 has been around 400 to 450 USD depending on tax and discounts, but its effective cost is reduced further by the inclusion of an Unraid license, which separately represents a non trivial software expense and is pre supported via a USB loader for straightforward deployment. While the N100 CPU and PCIe lane distribution place it below some competing platforms in raw performance, the combination of 10 GbE, mixed media bays, bundled software and small footprint makes it a distinct option for users who prioritise overall throughput and licensing value rather than maximum compute power.
The Lincstation N2 NAS is a solid upgrade over its predecessor, the N1, offering better connectivity, improved cooling, and more efficient hardware. The inclusion of 10GbE networking makes it a more appealing option for users who require higher data transfer speeds, and the passive and active cooling improvements ensure better thermal regulation under sustained workloads. With support for four M.2 NVMe SSDs and two SATA SSDs, the N2 provides flexible storage options, allowing users to build a high-speed, all-flash NAS setup. The Intel N100 processor and 16GB LPDDR5 memory deliver decent performance for most home and small business NAS applications, but the non-upgradeable memory may be a limiting factor for more demanding users. The compact, efficient design makes it an ideal NAS for those looking for a balance between power efficiency and performance.
That being said, the N2 does have a few drawbacks that may impact users looking for greater expandability. The lack of PCIe expansion slots means users cannot add additional NICs or storage controllers, making it less versatile compared to some competing NAS solutions. Additionally, while the 10GbE port is a significant upgrade, it is limited by PCIe bandwidth constraints, meaning users may not be able to fully utilize its maximum throughput in all scenarios. The USB connectivity options are decent, but having only one high-speed USB-C 10Gbps port may feel restrictive for those wanting multiple fast external connections. Furthermore, the reliance on a barrel-type power connector instead of USB-C is another missed opportunity for modernization.
Overall, the Lincstation N2 NAS remains a good choice for UnRAID users looking for an affordable, high-speed, all-flash NAS solution. It provides great energy efficiency, a streamlined setup process, and a solid mix of connectivity options. While it lacks some scalability features, for most home and small business users, it offers a compelling blend of performance, efficiency, and ease of use. If Lincplus continues refining their NAS lineup, future iterations with more robust networking, storage expandability, and minor refinements to cooling and connectivity could make it a standout competitor in the small NAS market.

The UnifyDrive UT2 is a dual M.2 NVMe mobile NAS that targets content creators and field teams who need portable, battery backed storage rather than a static rack or desktop system. It is built around an 8 core ARM platform (implemented as 2 quad core chips) with 8 GB of memory, 2.5 GbE networking, WiFi 6 support and can act as an access point, with additional connectivity via USB type C, USB type A and dual SD card slots. UniFi supplies its own NAS operating system, which covers file sharing, backup, containers and an app center but does not provide full virtual machine hosting, and the unit can also operate as a direct attached storage device over USB. An internal 2200 mAh battery provides roughly 2 hours of standalone use and the device can also be powered from an external USB power bank, allowing workflows where camera media is ingested on location, duplicated to other storage or cloud targets and then transported while tasks continue in the background. Pricing during 2025 has generally ranged between 399 and 599 USD depending on promotions, positioning the UT2 as a niche but distinct option for mobile data capture and collaboration rather than a traditional always on NAS.
The UnifyDrive UT2 Portable NAS offers a compact, portable storage solution designed for users who need on-the-go data management. Its features include a built-in battery, Wi-Fi 6, 2.5Gb Ethernet, HDMI output, and dual M.2 NVMe SSD slots, which together make it capable of handling media playback, file storage, and real-time collaboration. The UT2 also includes UDR selective RAID, one-touch SD card backups, and an AI-powered photo recognition system, all controlled through a user-friendly mobile app. These features position the UT2 as a versatile device for professionals such as photographers and content creators, who need portable, high-speed data storage and secure file management.
As a crowdfunded product, the UT2 is set to launch on Kickstarter, meaning there are some inherent risks associated with its development. While the hardware and software shown in the review appear polished and near completion, the final product may vary from the reviewed unit, and there is no guarantee of timely delivery or final quality. The early-bird price of $399 may appeal to those looking for a portable NAS, though the full retail price of $599 could place it in competition with larger, full-featured NAS systems. Potential backers should consider these factors when deciding whether to support the project.

Vous vous souvenez de mes conseils bien chiants sur l'importance de faire des backups ? Mais siii, ceux que je vous rabâche régulièrement depuis des années et que vous ne suivez pas du tout ?
Hé bien voici une histoire qui va vous donner envie de les suivre une bonne fois pour toutes (enfin j'espère... ^^) !
Dr Paris Buttfield-Addison, est basé en Australie et c'est un développeur Apple depuis 25 ans et le mec a écrit plus de 20 bouquins sur Objective-C et Swift, et co-organise le plus ancien événement développeur Apple non-officiel... Bref, c'est pas un random qui a téléchargé une app météo une fois.
C'est un évangéliste Apple depuis 30 ans.
Et bien du jour au lendemain, son compte Apple ID a été fermé sans aucune explication. Et bien sûr, impossible de faire un recours.
L'élément déclencheur de sa mésaventure c'est qu'il a essayé de racheter une carte cadeau Apple de 500 dollars pour payer son abonnement iCloud+ de 6 To. Le code a foiré, le vendeur lui a proposé un remplacement, et quelques temps après... boom, compte verrouillé.
Résultat, environ 30 000 dollars de matos Apple devenu inutilisable, des milliers de dollars de logiciels et médias achetés auxquels il n'a plus accès, plus d'iMessage non plus, et surtout des téraoctets de photos de famille qu'il ne peut plus récupérer.
Voilà comment 25 ans de souvenirs et de boulot se sont fait vaporiser...
Et le support Apple n'a pas dit grand chose à part que le compte a été fermé pour "non conformité avec les conditions". Pas d'autre explication ni possibilité de faire escalader sa demande au support. Tout ce qu'on lui a conseillé c'est de créer un nouveau compte...
On lui a également suggéré de se présenter physiquement au siège australien d'Apple comme si le mec allait prendre un billet d'avion pour aller plaider sa cause en personne. Bref, c'est bizarre comme réponse venant d'une boîte qui vaut 4000 milliards de dollars.
Le truc, c'est que cette histoire peut arriver à n'importe qui. Que ce soit chez Apple, Google ou Microsoft, nous sommes tous à la merci d'un algorithme qui décide un beau matin que notre compte est suspect ou à la bonne humeur de Donald Trump comme
ce qui est arrivé à ce juge
. Et bonne chance pour trouver un interlocuteur prêt à mouiller sa chemise pour vous...
Moi-même j'ai eu tellement de problèmes de synchro avec iCloud au fil des années que j'ai perdu des fichiers. C'est de la grosse merde donc optez pour un truc mieux si vous le pouvez.
Alors du coup, comment on évite ça ?
L'idéal c'est bien sûr l'auto-hébergement si vous avez le temps et les compétences (Oui, c'est gratuit que si votre temps ne vaut rien...sinon, faut relever les manches un peu ^^). Sinon, au minimum, faites des backups réguliers de vos données. Pour Apple Notes par exemple, y'a un outil qui s'appelle
Exporter
que j'aime beaucoup qui permet d'exporter toutes vos notes vers du Markdown ou du HTML comme ça le jour où Tim Cook décide que votre tronche lui revient pas, vous aurez au moins une copie de vos données quelque part.
Bref, ne faites jamais confiance à 100% à ces plateformes avec vos données les plus précieuses. Elles peuvent vous couper l'accès du jour au lendemain, et vous n'aurez aucun recours comme ce pauvre évangéliste qui a consacré sa vie à Apple...
Microsoft announced a series of significant security and resilience features coming to Windows 11 in 2026 at Ignite 2025. The updates focus on improving system recovery capabilities, enhancing encryption performance, and strengthening threat detection through native integration of advanced monitoring tools.
Black Friday 2025 has brought a round of uncommon discounts to Synology’s latest DiskStation models, with Amazon and B&H offering some of the strongest reductions across the current lineup. Synology hardware rarely receives notable price cuts, particularly on recently launched systems, so this is a useful opportunity for anyone planning an upgrade or expanding their storage. Whether you need a reliable home backup platform, a media server, or a compact office solution, several 2025 generation units are now available at lower prices. This guide outlines the best deals currently live and helps identify which DiskStation models offer the most value during this year’s Black Friday period.
Important note: Some users may have heard that Synology’s 2025 generation DiskStation models restrict the use of non-Synology hard drives. This was true earlier in the year, but Synology reversed the policy in October 2025. Current DiskStation units in this lineup now accept third-party HDDs from any manufacturer with no warnings or reduced functionality. However, M.2 NVMe SSD support remains limited to approved models, and the HDD restrictions still apply to RackStation systems and higher tier products in the broader Synology portfolio.

When setting up a NAS, one of the most important and long-lasting decisions you’ll make is choosing the right RAID level. This choice directly impacts how much protection you have against drive failures, how much usable storage space you retain, and how long rebuilds will take when things go wrong. Among the most debated options are RAID 5 and RAID 6, both of which use parity for data protection but differ in how much risk they can tolerate. RAID 5 offers single-drive failure protection with better capacity efficiency, while RAID 6 provides dual-drive fault tolerance at the cost of more storage overhead and longer rebuild times. It’s worth noting that although you can graduate a RAID 5 into a RAID 6 later if your needs change, this is a slow and resource-heavy process. On the other hand, RAID 6 cannot be reversed back into RAID 5, so it’s a decision that requires careful planning from the outset. The balance of speed, safety, capacity, and risk tolerance will determine which configuration is truly best for your setup.
IMPORTANT – It is essential to understand that RAID, whether RAID 5 or RAID 6, should never be considered a true backup solution. RAID protects against drive failures, but it cannot safeguard you from accidental deletion, malware, hardware faults beyond the disks, or disasters like fire and theft.
The TL;DR Short Answer – Over-Simplified, but….
Under 8 Bays = RAID 5
8 Bays or Over = RAID 5, or RAID 6 with Bigger HDDs
12 Bays or Over = RAID 6
If you are looking for simplicity, RAID 5 will usually give you the best balance of speed, storage efficiency, and cost, but it comes with higher risk. RAID 6 is slower to rebuild, consumes more usable capacity, and involves heavier parity calculations, but it provides a much stronger safety net against drive failures. For smaller arrays with modest drive sizes, RAID 5 can be entirely sufficient, especially when paired with reliable backups. However, as drive capacities continue to grow and rebuild times stretch into days, RAID 6 becomes more attractive because it can withstand the failure of two drives without losing the array. In essence, RAID 5 is about maximizing space and performance with a moderate level of safety, while RAID 6 is about maximizing resilience and peace of mind at the expense of capacity and speed. Choosing between them comes down to how valuable your data is, how large your drives are, and how much risk you are willing to tolerate during rebuild windows.
For systems with fewer than 8 bays, RAID 5 will usually be sufficient unless you are running especially large-capacity drives or operating at a business scale where data loss cannot be tolerated. Once you reach 8 bays or higher, RAID 6 should be seriously considered, as the chances of a second drive failing during a rebuild increase along with the overall storage pool size and the scale of potential loss. At 12 bays and beyond, RAID 6 is effectively mandatory, as relying on RAID 5 at that scale means gambling with too many points of failure and too much at stake if something goes wrong.

RAID 5 vs RAID 6 – Build Time and RAID Recovery Time
The initial creation of a RAID array, sometimes called synchronization or initialization, is one of the first differences you’ll notice between RAID 5 and RAID 6. A RAID 5 setup generally completes its initial build faster because it only has to calculate and assign a single parity block across the drives. RAID 6, by contrast, has to generate and distribute two independent parity values on every stripe, which increases the workload on the system. This means that on a fresh setup, RAID 6 will take longer to complete the synchronization process before the array is fully operational, though this is usually a one-time inconvenience at the beginning of deployment. For home and small office setups, this extra build time might not matter too much, but in larger systems with many terabytes of data, it can mean several hours or even days of extra initialization work compared with RAID 5.
The difference becomes more significant when a drive fails and a rebuild is needed. In RAID 5, the system only needs to reconstruct the missing data using the surviving disks and a single parity calculation, which usually makes recovery noticeably faster. RAID 6, however, must perform double parity calculations and restore both sets of parity information onto the replacement drive, extending the recovery window. On large modern HDDs where rebuilds can take dozens of hours, or sometimes multiple days, this extra time becomes a major factor. The trade-off is that RAID 6 offers much stronger resilience while this rebuild is in progress, because the system can continue to operate and survive even if another disk fails during the process. In other words, RAID 5 rebuilds faster but carries more risk, while RAID 6 rebuilds slower but provides a crucial safety margin during the vulnerable degraded state.
Here is a recent video (using the UniFi server platform) that talks about RAID 5/6 vs RAID 10 build times and parity from 777 or 404:
RAID 5 vs RAID 6 – Protection and Vulnerability
The most important factor when comparing RAID 5 and RAID 6 is how well they protect data when drives fail. RAID 5 uses single parity, meaning the system can survive one drive failure without losing data. However, if a second drive fails during the rebuild, the entire array is lost. RAID 6 adds dual parity, which allows the system to tolerate the loss of two drives simultaneously. This extra layer of protection is especially valuable during rebuild windows, which can take many hours or days on modern high-capacity HDDs. In practice, RAID 6 dramatically reduces the risk of catastrophic data loss, at the expense of slower rebuilds and less usable capacity. A subtle but often overlooked vulnerability is the issue of batch manufacturing. Many users buy multiple drives at once, often from the same supplier, meaning the disks may come from the same production batch. If there was a hidden flaw introduced during manufacturing, it is possible that more than one disk could develop problems around the same time. With RAID 5, this creates a dangerous scenario: a second disk failure during a rebuild results in complete data loss. RAID 6 provides a safety margin against these correlated failures by protecting the array even if two drives fail close together in time. Another major risk comes from unrecoverable read errors (UREs) that can occur during rebuilds. Because every sector of every remaining drive must be read to restore the lost disk, the chance of encountering a read error rises significantly with larger drives. In RAID 5, a single URE during rebuild can corrupt the recovery process, whereas RAID 6 has an additional layer of parity to compensate, making it much more reliable during rebuilds. This is especially important in arrays of 8 or more drives, where the probability of encountering at least one problematic sector grows. For users with large arrays or very high-capacity drives, RAID 6’s extra fault tolerance is the difference between a successful rebuild and complete data loss.
RAID 5 vs RAID 6 – Capacity and Price per TB
One of the clearest differences between RAID 5 and RAID 6 lies in how much usable capacity you end up with. RAID 5 only sacrifices the equivalent of a single drive’s worth of storage to parity, which makes it the more space-efficient option. In a six-bay system with 10TB drives, RAID 5 would deliver 50TB of usable storage, while RAID 6 would only provide 40TB. That 10TB difference can be substantial when you are working with large libraries of data such as media collections, surveillance archives, or backups. For users trying to maximize every terabyte of their investment, RAID 5 makes the most efficient use of available space. However, RAID 6’s higher storage overhead translates directly into a higher effective cost per terabyte. Since two drives are always reserved for parity, the total usable space is reduced, and the price you pay for storage per TB goes up. For small home users, this may feel like wasted potential, but the trade-off is the additional layer of fault tolerance. In environments where the cost of downtime or data loss far outweighs the cost of an extra disk, RAID 6 provides stronger long-term value despite the higher price per terabyte. Ultimately, the decision comes down to whether you are more concerned with minimizing cost and maximizing space, or ensuring redundancy and peace of mind.
RAID 6 vs RAID 5 + Hot Spare Drive?
Some users prefer to run RAID 5 with a dedicated hot spare drive rather than choosing RAID 6 outright. In this setup, a single extra disk sits idle until one of the active drives fails, at which point the spare is automatically used for the rebuild. This reduces the amount of time the array spends in a degraded and vulnerable state, since the rebuild begins immediately without waiting for a replacement disk to be manually installed. While this approach still leaves you with only single-drive fault tolerance, it can feel like a middle ground between RAID 5 and RAID 6. In terms of capacity, RAID 5 with a hot spare sacrifices the same amount of usable space as RAID 6, but it does not provide the same dual-drive protection. For arrays of six to eight drives, this compromise can make sense if you prioritize capacity efficiency and faster automated recovery, but once you move into larger-scale storage systems, RAID 6 remains the safer and more resilient option.
RAID 5 vs RAID 6 – Conclusion and Verdict
When choosing between RAID 5 and RAID 6, the decision comes down to weighing efficiency against resilience. RAID 5 is faster to rebuild, provides more usable storage, and costs less per terabyte, which makes it well suited to smaller NAS setups or users who prioritize capacity and speed. RAID 6, on the other hand, offers stronger protection against drive failures, making it far more reliable for larger arrays and higher-capacity drives where rebuild times are long and risks multiply. The general consensus is that RAID 5 can still be a smart choice for arrays under eight bays, but RAID 6 becomes the clear recommendation for systems of eight drives or more, and an essential requirement at twelve drives and beyond. Above all else, it is critical to remember that RAID is not a backup. Neither RAID 5 nor RAID 6 will protect you against accidental deletion, ransomware, hardware faults beyond the disks, or disasters such as fire or theft. RAID is a safety net that improves availability, but it must always be paired with a proper backup strategy if your data truly matters.

UniFi’s entry into the uninterruptible power supply market brings two distinct solutions tailored for professional and prosumer environments: the UPS-Tower desktop model and the UPS-2U Rackmount unit. The tower configuration provides 1,000VA / 600W of backup capacity and uses a single 12V, 9Ah lead-acid battery, while the larger 2U rackmount version scales up to 1,440VA / 1,000W with dual battery modules. Both adopt a line-interactive architecture with simulated sine wave output, a 6–10 ms transfer time, and Ethernet-based network management. Integration is handled natively within UniFi Network, where users can adopt, monitor, and configure the UPS directly from the UniFi Controller interface. For non-UniFi deployments, both models retain NUT (Network UPS Tools) compatibility for safe shutdown and system monitoring. This marks a significant expansion of UniFi’s ecosystem into power management and continuity—areas traditionally dominated by brands like APC and CyberPower—positioning UniFi’s UPS line as a bridge between smart network infrastructure and automated power protection.
The UniFi UPS-Tower 1000VA / 600W Review – Quick Conclusion
The UniFi UPS-Tower and UPS-2U deliver practical and ecosystem-focused power protection for small network environments. Both models emphasize integration and manageability rather than raw performance, providing stable 120V line-interactive backup power with simulated sine wave output. The tower model offers 600W of protection in a compact desktop enclosure, while the rackmount unit increases capacity to 1,000W with dual batteries. Integration through the UniFi Network Controller is straightforward, enabling central monitoring and alerting without external software. While limitations such as the lack of USB ports, PoE passthrough, and pure sine wave output restrict versatility outside the UniFi ecosystem, both units are solid entries for users seeking consistent, centrally managed backup power within UniFi-managed infrastructures.
The UniFi UPS-Tower UPS Review – Design & Connectivity
The UniFi UPS-Tower adopts a vertically oriented, compact chassis that measures 288 x 99 x 280.5 mm and weighs just over 8 kg. Its enclosure is built from a polycarbonate and ABS blend, which offers a balance between durability and low weight, and the overall shape resembles a small desktop speaker or heater.
The unit’s IP20 rating indicates it is intended for indoor use only, with ventilation panels positioned at the top, sides, and bottom to maintain airflow. During testing, internal temperatures averaged around 45–47°C after 24 hours of continuous operation, demonstrating stable thermal management for a unit of this density. The design is understated, with no LCD screen or physical display, relying instead on LED indicators and the UniFi interface for monitoring battery level and status.
In terms of connectivity, UniFi has implemented a clear division between power protection and control interfaces. On the rear panel, the UPS-Tower provides five surge-only outlets and five battery-backed surge-protected outlets, all of which are NEMA 5-15R ports suitable for 120V environments. The input connection uses a NEMA 5-15P plug, rated for 12A maximum load, supporting both 50 and 60 Hz operation. While this configuration is typical of compact line-interactive UPS units, the number of protected outlets is unusually high for its size, making it suitable for powering multiple small network devices, NAS units, or edge appliances simultaneously. However, only the five battery-backed ports will remain operational during a power loss.
UniFi has also included Ethernet management for remote monitoring and control. The rear I/O layout features a 100/10 MbE network connection that links the UPS directly into the UniFi ecosystem, as well as two GbE ports for surge in/out, allowing for protection of wired data paths. This implementation enables the UPS to send automatic notifications and power-state updates to the UniFi controller, ensuring that connected devices can safely power down when mains supply is interrupted. While users will not find USB connectivity here—a feature absent from both models—Ethernet management ensures seamless network-level integration with UniFi OS devices and provides remote monitoring capabilities not typically available in basic desktop UPS designs.
On the visual and operational interface side, UniFi relies on a multi-stage LED system to communicate battery and status information. A ring of LEDs on the front panel indicates power state, network connectivity, and battery percentage, with specific color patterns representing states such as initialization, adoption, or firmware upgrades. For example, a steady blue LED denotes normal operation, while flashing red signals a low battery, and alternating white/blue indicates firmware updating. This LED-centric approach aligns with UniFi’s existing product language and keeps the design minimalistic while relying on software integration for detailed telemetry.
Physically, the UPS-Tower fits neatly into a small office or studio environment, blending alongside UniFi routers or switches without dominating desk space. It operates quietly, with only a faint hum from the internal fan during battery mode. The 2U rackmount model, by contrast, uses a galvanized steel enclosure with front ventilation and nearly double the weight at 14 kg, prioritizing durability for data racks and wiring cabinets.
Both maintain an IP20 protection rating, ensuring basic safety against accidental contact but not dust or moisture resistance. Overall, UniFi’s approach emphasizes modularity, network integration, and compactness over display-driven functionality, positioning these UPS units as discreet but essential components within managed network setups.
The UniFi UPS-Tower UPS Review – Internal Hardware
Internally, the UniFi UPS-Tower follows a line-interactive architecture, combining voltage regulation with battery backup to ensure smooth transitions during power interruptions. The system utilizes an automatic voltage regulation (AVR) circuit that adjusts minor fluctuations in mains voltage without switching to battery mode, minimizing wear on the internal power cells. In the event of an outage or severe voltage dip, the UPS switches to battery operation within 6 to 10 milliseconds, maintaining output stability at 120V AC with a ±10% regulation margin. The waveform produced in battery mode is a simulated sine wave, which is adequate for most networking gear and consumer electronics, though not ideal for high-sensitivity audio, medical, or laboratory equipment. Power delivery remains consistent throughout short outages, allowing network hardware, NAS units, and servers to complete safe shutdown procedures.
The UPS-Tower contains a single 12V, 9Ah sealed lead-acid battery, user-removable via a bottom access panel. This design makes future maintenance straightforward, allowing owners to replace the battery when its capacity diminishes after several years of use. At full load (600W), the runtime averages around 2 minutes, while at half load, it extends to approximately 7 minutes before automatic shutdown. Recharge time to 90% capacity is listed at 6 to 8 hours. Thermal performance under sustained use is stable, and the inclusion of passive and active ventilation ensures no overheating under normal operating conditions. The system is also protected against short circuits, overloads, and over-voltage faults, automatically tripping into fault mode if thresholds of 110% to 120% load are exceeded.
Comparatively, the UPS-2U Rackmount uses a dual-battery setup with two 12V, 9Ah lead-acid modules to achieve 1,440VA / 1,000W output capacity. It shares the same waveform and transfer time but provides slightly extended runtime—2.3 minutes at full load and 8 minutes at half load—thanks to the added battery reserve. It also benefits from a galvanized steel chassis that enhances durability and is better suited for professional rack environments. Both systems are NDAA-compliant and certified under FCC, IC, UL 1778, and CSA C22.2 No. 107.3, ensuring safety and performance standards for commercial and residential use. In both models, system management and network telemetry are handled by a dedicated network controller chip, enabling UniFi OS integration and data synchronization with other UniFi devices.

The UniFi UPS-Tower UPS Review – Functionality
The UniFi UPS series is built around simplicity and ecosystem-level integration rather than feature-heavy configuration. Both the UPS-Tower and UPS-2U connect directly to the UniFi Network controller via Ethernet, where they appear alongside other UniFi devices for adoption. Once added, users can view real-time battery percentage, load level, input/output voltage, and system temperature directly from the UniFi interface. The units are also capable of sending power event notifications when mains power fails or returns, ensuring administrators receive alerts through the existing UniFi management system without relying on third-party monitoring software. This network-level approach allows the UPS to act as both a power backup and an automated coordination point for controlled shutdowns across UniFi infrastructure, such as Dream Machines, switches, or NAS units.
Integration with non-UniFi devices is handled through Network UPS Tools (NUT) compatibility. This makes the UPS-Tower particularly flexible in mixed environments where NAS devices or servers from other vendors, such as Synology or QNAP, require graceful shutdown when the UPS switches to battery mode. Users can define credentials and associate the UPS with NUT clients on the same network to relay status and trigger automated shutdowns once the battery reaches a predefined threshold. Although the review highlighted the lack of USB connectivity, which restricts plug-and-play use with devices expecting a traditional USB UPS handshake, the Ethernet management layer compensates by offering wider network-based communication. However, features such as per-device runtime configuration or selective port control are not yet implemented, leaving shutdown scheduling dependent on firmware updates or future model revisions.
The control and monitoring interface remains minimalistic, relying heavily on UniFi’s centralized GUI rather than onboard interaction. LEDs on the chassis provide a clear visual indication of status—covering power mode, adoption state, and battery level—but all deeper telemetry must be accessed through UniFi Network. Once paired, users can also configure email or push notifications for voltage irregularities, battery health alerts, and firmware updates. It is important to note that the current firmware does not support pure sine wave operation or lithium-ion battery upgrades, though UniFi has stated that future models will expand the portfolio to include these higher-end options. In its present form, the UPS-Tower and UPS-2U focus on stability, ease of deployment, and unified management within a single software environment, making them efficient for UniFi users seeking automation without added complexity.

The UniFi UPS-Tower UPS Review – Conclusion and Verdict
The UniFi UPS-Tower and UPS-2U represent the brand’s first foray into managed backup power systems, designed primarily to extend the reliability and consistency of the broader UniFi ecosystem. Both units share the same line-interactive architecture, simulated sine wave output, and Ethernet-based monitoring, offering a predictable and easily managed experience for users already invested in UniFi infrastructure. Their minimalist design, compact footprint, and seamless adoption through the UniFi Network Controller make them suitable for environments where simplicity, remote monitoring, and integration outweigh the need for advanced runtime management or pure sine wave output. For most small network or NAS setups, either model will provide adequate protection during short outages and brownouts, while ensuring systems are safely powered down when battery capacity is depleted.
However, their appeal remains closely tied to the UniFi ecosystem. The absence of USB connectivity, PoE passthrough, and lithium-ion battery options limits their usefulness in heterogeneous or high-performance environments. Users seeking pure sine wave support, longer runtimes, or advanced per-device control will likely need to wait for the next generation of UniFi UPS models, which the company has already suggested will expand to include these options. As they stand, the UPS-Tower and UPS-2U are well-built, tightly integrated, and cost-effective for UniFi users, but less compelling for those operating outside that ecosystem. They function precisely as intended: reliable, network-aware power backups for UniFi-managed systems, providing foundational stability rather than feature innovation.
