QNAP Qu405, Qu605 and Qu805 NAS Coming Soon for Home and SMB Users

QNAP has officially launched the QuX05 series in the Eastern market, introducing three new desktop NAS systems: the Qu405 (4-bay), Qu605 (6-bay), and Qu805 (8-bay). Designed to refresh QNAP’s mid-range portfolio, these models target home users seeking centralised storage, creative professionals handling large-scale multimedia, and small to medium-sized businesses in need of reliable file servers with room to grow. Hardware configurations are offered in two processor options, with the Intel Core 3 N355 eight-core chip running up to 3.9 GHz for higher performance workloads, and the Intel N150 quad-core option at up to 3.6 GHz for cost-conscious deployments. All units adopt DDR5 memory, available in 8 GB or 16 GB SKUs, with support capped at 16 GB via a single slot, which while modest, still provides a step up in bandwidth over DDR4 used in older NAS systems. Storage capacity scales with the number of bays, from four in the Qu405 to eight in the Qu805, and each model also includes two M.2 PCIe Gen3 slots that can be assigned for cache acceleration or used as part of the storage pool. Connectivity has been modernised with dual 2.5GbE ports supporting SMB Multichannel and Port Trunking, USB 3.2 Gen2 across Type-A and Type-C, and a dedicated HDMI output capable of 4K60 playback or VM projection, ensuring these systems can function as both storage appliances and multimedia platforms.

The QuX05 series also benefits from QNAP’s dual operating system approach, allowing users to deploy either the established QTS software environment or the QuTS hero ZFS-based platform for improved data protection, inline deduplication, and snapshot functionality. Integrated AI-powered tools such as QuMagie for photo organisation, Qsirch for semantic search, and Qfiling for automated archiving further extend the usability of the series, making it suitable for both consumer and business applications. The timing of this release is notable, as QNAP’s TS-x64 and TS-x53E systems, including the TS-264, TS-464, and TS-664, are now over three years old, and while still supported, they increasingly feel dated in comparison to more recent offerings. At the same time, competition has intensified with new entrants such as UGREEN, Minisforum and Aoostar, which has gained traction in the NAS sector with aggressive pricing and updated hardware designs, underlining the demand for innovation. Against this backdrop, the Qu405, Qu605, and Qu805 arrive as QNAP’s latest response, bringing updated architecture, refined airflow and thermal design, modernised connectivity, and versatile system features to a market that is both more competitive and more demanding than before.

QNAP Qu405, Qu605 and Qu805 NAS Hardware Specifications

The Qu405, Qu605, and Qu805 are built around the latest Intel processors, with each model available in two distinct variants. The high-performance option uses the Intel Core 3 N355, an eight-core processor with a maximum turbo frequency of 3.9 GHz, paired with Intel UHD Graphics supporting 32 execution units. This CPU is part of Intel’s Twin Lake platform and offers a modest set of PCIe Gen3 lanes, sufficient for supporting dual 2.5GbE controllers, two M.2 NVMe slots, and other onboard I/O. The Lite models, intended for users with lighter requirements or stricter budgets, adopt the Intel N150 quad-core processor running at up to 3.6 GHz, paired with a reduced integrated graphics configuration and fewer available PCIe lanes overall. Both CPU options support AES-NI hardware-accelerated encryption, ensuring data security is handled with minimal performance impact, while the choice between N355 and N150 provides a balance between performance scaling and affordability across the QuX05 range.

Memory is standardised across the series, with all three devices supporting DDR5 SODIMM modules operating at up to 4800 MHz. SKUs are available with either 8 GB or 16 GB preinstalled, and although only a single memory slot is provided, limiting maximum capacity to 16 GB, the use of DDR5 brings notable improvements in throughput and responsiveness compared to the DDR4 used in older generations. The memory arrangement also highlights the target audience of the QuX05 series: home and SMB users who need fast but manageable workloads rather than large-scale enterprise deployments that require extensive memory pools. The systems also include 8 GB of onboard eMMC NAND for essential system functions, ensuring that firmware and OS-level features remain responsive even during heavy storage activity. Unlike some higher-end SMB-focused NAS devices, there is no dedicated PCIe expansion slot for upgrades such as 10GbE, HBAs, or GPU cards. This omission is likely linked to the reduced lane count of the N150 and N355 processors, which restricts available bandwidth for add-in cards. Instead, QNAP has chosen to distribute available lanes across built-in features such as dual 2.5GbE ports and dual NVMe slots, a trade-off that prioritises out-of-the-box functionality over modular expansion.

Storage options are one of the main areas where the QuX05 series differentiates itself by bay count. The Qu405 provides four 3.5-inch SATA bays, the Qu605 six, and the Qu805 eight, with each also capable of accommodating 2.5-inch SATA SSDs for flexible configurations. All bays support hot-swapping, allowing drives to be replaced without shutting down the system. Alongside the main drive bays, every model includes two M.2 2280 NVMe slots running at PCIe Gen3 x1. While not offering the bandwidth of Gen3 x4 or Gen4, these slots are sufficient for cache acceleration or tiered storage, with QNAP’s Qtier software automatically balancing frequently accessed files between SSDs and hard drives. This approach provides both capacity and performance, especially for environments that mix multimedia storage with frequent small file access.

Connectivity is consistent across all three models. Networking is based on dual 2.5GbE RJ45 ports, supporting link aggregation for bandwidth scaling and redundancy as well as SMB Multichannel for improved multi-session performance. Local I/O includes two USB 3.2 Gen2 Type-A ports at the rear, a front-facing USB 3.2 Gen2 Type-C port with one-touch copy, and HDMI output capable of 4K at 60 Hz. Most SKUs list HDMI 2.1, while some Lite versions list HDMI 2.0, so capabilities vary depending on configuration. Power requirements scale with chassis size, from a 96 W adapter for the Qu405, to 120 W for the Qu605, and 150 W for the Qu805, with reported average consumption under full drive load measured at approximately 63 W, 84 W, and 103 W respectively. Additional features include system buzzers for hardware alerts, Kensington lock slots for physical security, and redesigned airflow systems that improve cooling efficiency compared to older QNAP mid-range hardware. Together, these specifications establish the QuX05 series as a modernised platform that balances capacity, performance, and power efficiency across three scalable sizes.

Comparison Between the QuX05 Series and TS-x64 & TS-x53E Series

The arrival of the QuX05 range marks a generational update in QNAP’s mid-tier NAS catalog, directly inviting comparison with the company’s established TS-x64 series (TS-264, TS-464, TS-664) and the TS-x53E line (TS-253E, TS-453E). While the older models remain capable and still receive firmware updates, they are now over three years old and show their age in several areas. The TS-x64 units rely on Intel Celeron N5095/N5105 processors, DDR4 memory, and single 1GbE networking as standard, with expansion slots required for faster networking or NVMe storage. The TS-x53E series, launched in 2022, provided an alternative path with dual 2.5GbE ports and built-in M.2 NVMe slots, though they were capped at DDR4 memory and lacked PCIe upgrade slots, restricting long-term flexibility. In contrast, the QuX05 systems use Intel’s newer N355 and N150 processors, move to DDR5 memory, and integrate features such as dual 2.5GbE, NVMe SSD caching, and HDMI 4K output directly into the base platform, reducing the reliance on add-in cards or optional upgrades.

 

Another major distinction lies in how QNAP has approached expandability. The TS-x64 devices maintain a traditional PCIe slot for upgrades such as 10GbE networking or storage accelerators, something absent from both the QuX05 and TS-x53E series. In the QuX05 range, the limited PCIe lanes of the chosen Intel processors have been redistributed to provide onboard dual NVMe slots and dual 2.5GbE networking, effectively prioritising out-of-the-box functionality over modular expansion. For many home users and SMBs, this built-in approach is practical, but for environments needing high-speed networking or specialised PCIe hardware, the TS-x64 remains more adaptable. Overall, the QuX05 line represents QNAP’s attempt to modernise its mainstream desktop NAS range by integrating features previously seen only in higher-end or expansion-reliant models, offering a balance of performance, efficiency, and simplified setup against the backdrop of older but more expandable TS systems.

QNAP Qu405, Qu605 and Qu805 NAS

Early reports from Eastern markets suggest that QNAP intends to position the QuX05 series at a highly competitive level, targeting the same price bracket traditionally occupied by mid-range consumer and SMB NAS devices. Instead of focusing on premium pricing, QNAP appears to be bundling enterprise-class features such as DDR5 memory, dual 2.5GbE connectivity, and built-in NVMe caching into systems expected to fall within the reach of prosumers and small studios. This approach contrasts with past strategies where certain features were locked behind higher-end models or optional expansion cards. The Qu405 and Qu605 are anticipated to scale more affordably due to their lower bay counts, while the Qu805 represents the higher-capacity option. All systems ship with QNAP’s standard two-year warranty, with the option to extend coverage to five years, which remains an important consideration for business users seeking predictable long-term support. Early indications also point to launch bundles or promotional packages, including potential accessories or service benefits, underlining QNAP’s intention to add value in a market that has become crowded with alternatives from newer NAS vendors.

In terms of release timing, the Qu405, Qu605, and Qu805 have already been introduced to the Eastern region, with wider international distribution expected before the close of 2025. Based on QNAP’s established release cycle, this typically means North American and European availability will follow within one or two months of the initial rollout. The timing reflects both market demand and competitive pressure, as the TS-x64 and TS-x53E families are now over three years old, and users have been increasingly vocal about the need for refreshed hardware. With rival solutions from UGREEN, Asustor, and other consumer-oriented NAS makers gaining attention, QNAP’s scheduling suggests an urgency to reassert its role in the mainstream NAS segment. The QuX05 series therefore not only modernises QNAP’s desktop lineup but also aims to arrive quickly enough to counter competing releases, ensuring it remains a viable choice for prosumers, creative teams, and small business deployments into 2026 and beyond.

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

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

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

Important Disclaimer and Notes Before You Buy

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

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