This article covers AOOSTAR WTR PRO AMD Ryzen 7 5825u 4ベイNASミニPC.
Overview
The AOOSTAR WTR PRO 5825U is a 4-bay NAS mini PC powered by the AMD Ryzen 7 5825U processor. It ships as a barebone kit—no RAM, no SSD included—so you'll need to supply your own DDR4 SO-DIMM memory, M.2 NVMe SSDs, and SATA drives. The chassis accepts up to four 3.5-inch or 2.5-inch SATA drives, each bay supporting up to 22TB for a total raw capacity of 88TB. Two additional M.2 2280 NVMe slots are available for OS drives or cache acceleration. The Ryzen 7 5825U offers 8 cores and 16 threads, with a base clock of 2.0GHz and a boost up to 4.5GHz. The integrated Radeon Vega graphics can drive up to three 4K displays simultaneously, making it suitable for media server duties. Power consumption stays between 15W and 25W under typical loads, ideal for always-on operation. A 12cm fan with intelligent speed control keeps noise levels low while maintaining adequate cooling.
Connectivity & Compatibility
Network connectivity is handled by dual 2.5GbE LAN ports, supporting link aggregation or failover. Video outputs include DisplayPort 1.4 (up to 4K144Hz), HDMI 2.1, and USB-C with DisplayPort Alt Mode—allowing up to three independent 4K displays. USB ports consist of two USB 3.0 and two USB 2.0 ports, plus a Micro SD card slot. Memory compatibility requires laptop-style DDR4 SO-DIMM modules running at 3200MHz, with a maximum capacity of 64GB (2x32GB). Storage bays accept both 3.5-inch and 2.5-inch SATA drives (any capacity up to 22TB per bay). The two M.2 slots are PCIe NVMe only (no SATA M.2 support). The system is compatible with Windows 11 Pro, Linux distributions, and NAS-oriented operating systems such as TrueNAS, Unraid, or OMV.
Product Info
The AOOSTAR WTR PRO 5825U launched in late 2025 and is available on Japan for approximately ¥73,829 (as of July 2026). The product carries a 12-month warranty from the purchase date, with support available via email. Market positioning sits in the mid-range barebone NAS mini PC segment. Compared to pre-built NAS appliances from Synology or QNAP, this unit offers more flexibility in component selection and OS choice, but requires a hands-on approach to assembly and configuration. It's a step above entry-level single-bay Raspberry Pi-based NAS solutions and offers superior CPU performance for transcoding and virtualization.
Best Use Cases
DIY NAS builders: Users who want full control over their storage configuration—RAID level, file system, and OS—will appreciate the four hot-swappable SATA bays and dual NVMe slots. The barebone nature allows cost savings by reusing existing RAM and SSDs, and the low power draw makes it suitable for always-on file servers or media libraries. Home server / media transcoding: The integrated Radeon Vega GPU handles hardware-accelerated video transcoding for Plex or Jellyfin, so a dedicated graphics card isn't needed. This makes the WTR PRO a compact and energy-efficient solution for streaming 4K content to multiple devices. However, it's not suited for gaming or heavy GPU compute workloads. * Software router / network appliance: With two 2.5GbE ports, users can deploy pfSense, OPNsense, or OpenWrt for routing, firewall, or VPN server duties. The ample RAM capacity (up to 64GB) allows for running multiple virtual machines alongside the router OS. Note that official compatibility lists for NIC chipsets are not provided, so some research may be required before choosing a software router distribution.
