AI Verdict
A 2-bay NAS with an Intel Celeron J4125 quad-core CPU, 2 GB DDR4 RAM, and dual 2.5GbE and 1GbE LAN ports, designed for home and small office data centralization.
This NAS is a situational fit because its dual 2.5GbE and 1GbE ports and expandable 2 GB DDR4 memory up to 6 GB are strong for faster home or small office networks, but the two-bay limit caps its maximum raw storage at 40 TB. It's a good choice if your data needs align with its capacity and performance, and you're comfortable with a new product.
If you need more storage capacity or higher performance for virtualization, look for a NAS with more drive bays (e.g., 4-bay or 8-bay) and a more powerful CPU like an AMD Ryzen or Intel Core i3/i5.

Pros
- Includes a 2.5 Gigabit Ethernet port for faster network transfers, exceeding typical 1GbE speeds.
- Memory is expandable up to 6 GB (2 GB + 4 GB), allowing for more demanding applications.
- Supports Btrfs file system with snapshot technology for advanced data protection and recovery.
- Compatible with third-party drives since DSM 7.3, offering flexibility in drive selection.
- Features a quad-core Intel Celeron J4125 processor, providing capable performance for various tasks.
- Offers comprehensive backup solutions for PCs, smartphones, and cloud apps, supporting 3-2-1 backup configurations.
Cons
- Only comes with 2 GB of non-ECC DDR4 memory, which might be a bottleneck for heavier workloads without an upgrade.
- Limited to two drive bays, restricting maximum raw storage to 40 TB (with 2x 20TB drives).
- The bundle includes 2x 8TB drives, providing 16TB raw capacity, which may be insufficient for users with large data archives over time.
- The Intel Celeron J4125, while capable, is not a high-performance CPU for intensive virtualization or multiple concurrent transcoding tasks.
Dimension Scores
The sequential read/write speeds of over 282/217 MB/s, combined with a 2.5GbE port, are above average for a 2-bay NAS in its class.
Synology's Btrfs file system with snapshot technology and support for RAID 1 (mirroring) provide advanced data protection features, contributing to reliability.
The 16TB bundle (2x 8TB drives) offers a solid starting capacity, and the system can expand up to 40TB raw, which is average for a 2-bay system but not for larger data needs.
The NAS is compatible with 3.5" SATA HDDs and 2.5" SATA SSDs, and now supports third-party drives since DSM 7.3, offering broad hardware compatibility.
Best For
- Home users needing a central hub for photo and video storage and sharing.
- Small offices requiring file sharing, data backup, and basic surveillance capabilities.
- Users who need faster-than-gigabit network speeds for file transfers to and from the NAS.
- Individuals looking for advanced data protection features like Btrfs snapshots.
Not Recommended For
- Businesses needing high-performance virtualization hosts or extensive database servers.
- Users with immediate needs for more than 40 TB of raw storage capacity.
- Anyone expecting a product with existing user reviews and long-term feedback, as it's not yet released.
Watch Out For
- No user feedback available as the product's release date is October 23, 2025, so real-world issues are unknown.
- The included 2 GB RAM might require an immediate upgrade to 6 GB for smoother operation with multiple applications.
- While supporting 2.5GbE, your entire network infrastructure (switches, other devices) must also support 2.5GbE to fully utilize the speed.

Buying Guide
When looking at a NAS like this, you're essentially buying your own personal cloud storage and server. You need to think about how much data you have now, and how much you expect to have in a few years. Also, consider what you'll use it for beyond just storing files – things like media streaming, surveillance, or running small applications. The network ports are crucial for how fast you can get data to and from it.
Intel Celeron J4125 Quad-Core
This is the brain of your NAS. A quad-core Celeron is capable for general file serving, backups, and light media tasks, but it won't handle heavy video transcoding for multiple users or complex virtual machines without breaking a sweat. Think of it like the engine in your car – enough for daily driving, but not a race car.
2 GB Non-ECC DDR4 SODIMM (expandable to 6 GB)
This is the NAS's working memory. 2 GB is a starting point; if you plan to run multiple Synology apps, use Docker containers, or have many users accessing it simultaneously, upgrading to 6 GB will make everything feel much snappier. It's like having more RAM in your computer – more space for programs to run smoothly.
1 x 2.5 GbE and 1 x 1 GbE RJ-45 LAN-Port
These are your network connections. The 2.5 GbE port is a big deal because it's 2.5 times faster than standard 1 GbE, meaning quicker file transfers if your home network supports it. If you're moving big files (like 4K videos), this speed boost is noticeable. It's like having a wider highway for your data.
Alternatives
If you need more raw storage capacity or plan to run more demanding applications, look for NAS devices with more drive bays (e.g., 4 or 6 bays) and potentially a more powerful processor like an AMD Ryzen or Intel Core i3.
