First NAS for a self-hosted box: Synology vs mini PC
The question is usually asked as a hardware question and is actually a maintenance question. Both options run the same containers. What differs is who fixes it at 11pm when the family photos are not loading, and how much of your attention the box charges you per month.
The two architectures compared:
| Option | Buy this if | The costs nobody mentions | Link |
|---|---|---|---|
| Turnkey NAS | Storage is primary, other people in the house depend on it, or you would rather spend evenings on the services than on the platform | Vendor lock-in on the volume format; deliberately modest CPUs, so check video transcoding specifically if media serving is the plan | — |
| Mini PC | Services are primary, you want current-generation CPU for a fraction of the money, or you enjoy the platform work | You become the vendor: backups, updates, disk health and the recovery plan are yours; USB-attached disks can disconnect during a write | Mini PC N100 16GB |
The turnkey NAS
A purpose-built appliance with a vendor OS, a web UI, and an app store. Drive bays, hot swap, and a supported path for the thing everyone eventually wants: a redundant array that survives one dead disk.
Buy this if the box’s job is storage first and services second, if other people in the house depend on it, or if you would rather spend your evenings on the services than on the platform.
The costs nobody mentions: vendor lock-in on the volume format, and CPUs that are deliberately modest, so hardware video transcoding may or may not be present on the model you are looking at. Check that specifically if media serving is the plan.
The mini PC
A small x86 machine, your own OS, containers on top, and storage over USB or one internal drive to start.
Buy this if the box’s job is services first and bulk storage later, if you want current-generation CPU performance for a fraction of appliance money, or if you enjoy the platform work.
The costs nobody mentions: you are now the vendor. Backups, updates, disk health monitoring, and the recovery plan are yours. USB-attached disks are fine until they are not, and “not” arrives as a disconnect at 3am during a write.
The decision in one line
If losing the data would be a family incident, buy the appliance. If losing the data would be an inconvenience, buy the mini PC and spend the difference on backup.
RAID is not a backup, and this is where beginners lose data
Redundancy protects against a disk dying. It does not protect against deletion, ransomware, a bad cable corrupting writes, or the flat that the box lives in. The rule is three copies, two media, one offsite, and the offsite copy is a subscription rather than a purchase.
What to check before buying either
- Drive bays you need now plus one, because arrays grow badly
- RAM upgradeable or soldered, since containers eat RAM before CPU
- NVMe slot present, for a cache or for the OS
- Idle power draw, because this machine runs 8,760 hours a year and that is the real running cost
- Ethernet speed, 2.5GbE is now common and 1GbE will bottleneck a modern array
- Noise, if it lives anywhere near where you sleep
The one drive spec that matters
CMR, not SMR. Shingled drives rewrite overlapping tracks and behave badly during array rebuilds, which is exactly when you need them to behave well. Manufacturers have shipped SMR into NAS-labelled lines before; check the specific model number rather than the product family.
Frequently asked questions
Is a Synology NAS better than a mini PC for self-hosting?
It depends on your priority. Synology is better if storage is primary, others depend on the box, or you want a supported platform. A mini PC is better if services are primary, you want more CPU for less money, or you enjoy the platform work. Both run the same containers.
What is the main disadvantage of a mini PC NAS?
You become the vendor. Backups, updates, disk health monitoring, and the recovery plan are all yours. USB-attached disks are fine until they disconnect during a write at 3am. The savings come with maintenance responsibility.
Do I need RAID for my first NAS?
RAID protects against a single disk dying. It does not protect against deletion, ransomware, or a bad cable corrupting writes. The rule is three copies, two media, one offsite. RAID is for uptime, not backup.
What is the difference between CMR and SMR hard drives?
CMR (Conventional Magnetic Recording) writes tracks independently. SMR (Shingled) overlaps tracks and performs badly during array rebuilds, which is exactly when you need reliability. Manufacturers have shipped SMR in NAS-labelled lines; always check the specific model number.
How much RAM does a home NAS need?
Containers eat RAM before CPU. 4GB is the floor for a basic file server. 8GB is comfortable for a few services. 16GB lets you run media servers, databases, and more containers. Check whether RAM is upgradeable or soldered before buying.
Start smaller than you think
The most common first-NAS mistake is buying four bays for a service you have not yet run. Run the containers on whatever machine you already own for a month. The workload you actually have will tell you which box to buy, and it is usually smaller and cheaper than the one on the forum.
