Minisforum has announced the S5, a fanless 5-bay all-flash NAS built around an Intel Core 3 304 CPU, supporting up to 40 TB of NVMe storage and featuring an edge-cloud AI agent architecture with a 15 TOPS NPU. It's aimed at creative professionals and home users who want fast, quiet, always-on storage.
MINISFORUM has introduced the S5, a fanless 5-bay all-flash NAS designed for users who want fast local storage without the noise of spinning drives or cooling fans. The S5 runs on an Intel Core 3 304 processor with 5 cores and a boost clock of 4.3 GHz, and it supports five M.2 NVMe SSDs for up to 40 TB of total storage. Networking comes via one 10GbE and one 2.5GbE port, along with Wi-Fi and dual USB4 ports rated up to 40 Gbps.
According to MINISFORUM, the all-flash design delivers up to 6x faster sequential read speeds and up to 100x faster random read speeds compared to traditional HDD-based NAS units, which should benefit workflows involving 4K/8K video, RAW photo libraries, and other large creative assets. The fanless chassis uses a heat pipe and cooling fins for passive cooling, and MINISFORUM's own lab testing found the CPU sustained around 15 W under combined stress at 25°C ambient, suggesting a focus on quiet, energy-efficient operation rather than peak performance.
One of the more distinctive aspects of the S5 is its edge-cloud collaborative AI architecture. A built-in NPU rated at 15 TOPS (INT8) allows a local AI agent to stay active around the clock, handling tasks like semantic retrieval and local data scheduling even when a user's main PC is powered off. MINISFORUM frames this as a 'private digital employee' that works alongside cloud-based large language models, which handle more complex reasoning and decision-making.
The S5 is positioned for both small creative studios needing shared high-speed storage and home users looking to store 4K media or personal libraries with less noise. It's available now in two configurations: a 12 GB LPDDR5x + 128 GB UFS model with no included NVMe storage, and a version bundled with 20 TB of NVMe storage that MINISFORUM says will ship in early November.
