What Buyers Say
What surprised me most is how many users pointed out the physical build quality; the metal chassis and drive bays feel sturdy, not cheap. While the hardware, especially the N5105 CPU and dual 2.5GbE, gets a lot of praise for its speed and upgrade potential, the software experience seems to be a mixed bag. Some find the ADM operating system's interface less intuitive and a bit dated compared to competitors, particularly the surveillance app. However, the inclusion of four M.2 NVMe slots is a big win for accelerating storage or running the OS on SSDs to keep HDDs spun down.
“Look, the hardware on this thing is a beast for the money, especially with those M.2 slots and 2.5GbE, but man, I wish the software felt as modern as the guts inside. Still, it gets the job done fast.”
Common Praise
- The Intel Celeron N5105 CPU provides a noticeable performance boost over older NAS models.
- Four M.2 NVMe slots allow for flexible SSD caching or dedicated fast storage.
- Dual 2.5 Gigabit Ethernet ports significantly improve network transfer speeds.
- The option to add a 10GbE card via PCIe slot is a future-proofing benefit.
- Robust metal construction of the NAS and drive bays feels durable.
- Effective ventilation keeps components cool, even with multiple SSDs installed.
Common Complaints
- The ADM operating system's user interface can feel less polished and intuitive than rival platforms.
- Some users find the placement of certain software options confusing within ADM.
- The surveillance application is considered basic and not as feature-rich as expected.
- The base 4GB RAM can be limiting for advanced use cases without an upgrade.
Ownership Tips
- Running the OS on M.2 SSDs allows the HDDs to remain spun down, reducing noise and power consumption when not actively accessed.
- Upgrading the RAM makes a noticeable difference in responsiveness, especially when running multiple applications or Docker containers.
- The 2.5GbE ports require a compatible switch or router to realize their full speed potential.
- While the physical build is sturdy, the fan can be audible, especially if placed in a quiet room.
Frequently Asked Questions
Can I upgrade the RAM in this NAS?
Yes, the 4GB DDR4-2933 SO-DIMM RAM is expandable up to a maximum of 16GB.
Does this NAS support 10 Gigabit Ethernet?
It comes with dual 2.5 Gigabit Ethernet ports, but it also has a flexible PCIe slot that allows for expansion with a 10 Gigabit Ethernet card.
What kind of drives can I use with this NAS?
The NAS supports 4 x 2.5"/3.5" SATA drive bays for traditional hard drives or SSDs, and it also has four M.2 NVMe slots for PCIe 3.0 SSDs.
Is the CPU powerful enough for 4K video transcoding?
Yes, the Intel Celeron N5105 Quad-Core processor is capable of 4K transcoding.
Does this NAS come with hard drives?
No, this model is sold as a 'diskless' unit, meaning you will need to purchase and install your own hard drives or SSDs.
Buying Guide
When you're looking at a NAS like this, you're essentially buying a mini-computer designed for storage. The 'no drive' part means you need to buy hard drives or SSDs separately, which will be your actual storage. Think about how much data you have now and how much you expect to have in a few years. Also, consider what you'll be doing with it: just storing files, streaming 4K movies, or running apps and virtual machines? That dictates the CPU, RAM, and network speed you need.
Quad-Core 2.0GHz Processor (Intel Celeron N5105)
This is the brain of your NAS. A faster processor means it can handle more tasks simultaneously, like streaming a 4K movie while backing up your computer, without slowing down. The N5105 is a modern, capable chip for home and small office use.
4 M.2 NVMe Slots (PCIe 3.0)
These are for super-fast SSDs. You can use them as a cache to speed up access to frequently used data on your slower hard drives, or as dedicated volumes for applications that need high performance, like video editing projects.
Dual 2.5GbE
This refers to the network ports. Standard home networks are usually 1 Gigabit Ethernet. 2.5 Gigabit Ethernet is 2.5 times faster, meaning you can transfer large files to and from your NAS much quicker, especially if your other devices and network switch also support 2.5GbE.
4GB DDR4 RAM (Expandable to 16GB)
RAM is like the short-term memory of your NAS. More RAM allows the NAS to run more applications and handle more users simultaneously without getting bogged down. While 4GB is okay for basic tasks, upgrading to 8GB or 16GB can significantly improve performance for heavier workloads.
Alternatives
If this model doesn't quite fit, look for NAS units with more drive bays if you need massive raw storage, or models with a more powerful CPU (like a Ryzen or Core i3) and more base RAM if you plan on heavy virtualization or running many demanding server applications.
