How to choose between Synology and Feiniu? I used Synology for two years before installing Feiniu, running both sets for a long time. Here's a comparison chart for you to copy

my family currently has two NAS systems online simultaneously: one Synology DS220+, bought in 2023, has run over 20,000 hours; I saved up a small N100 PC myself, installed Feiniu fnOS, and ran it for over half a year. When people around me ask me, "Should I choose Synology or Feiniu for NAS systems?" I never give a single answer, because these two products are fundamentally different — one is software purchase with hardware included, the other is installing the system yourself. But if I were to break it down, it wouldn't take half an hour to finish, so I decided to write it down as a single article. If you're still struggling, first take the position first, then look at the details.

first clarify the foundations of both sides: one is the finished product, the other is the system

Synology is a "whole machine" business. The metal box you paid for isn't worth more than the hardware—the DS220 + J4025 CPU and 2GB RAM, and when you open it up, the parts cost at most a little over a thousand yuan—the extra 1,000 yuan you pay is the DSM system and its after-sales service. DSM is essentially a prepackaged Linux, with web backend, mobile app, package center, and QuickConnect remote access—all set up for you, ready to use right after booting. The price is hardware locked down: the official memory only recognizes 2G expansion, the network port is gigabit, want to upgrade? There was no upgrade, so the whole machine could only be replaced.

Feiniu is the opposite. It's a free domestic system (fnOS) installed on your own hardware—N100 mini PC, old laptop, mining scraps, or even a 300-yuan N1 box. Hardware you can build however you like: my N100 comes with 16GB RAM and a 2.5G Ethernet port, costing 1,200 yuan, half the price of the DS220+, and its performance is far superior to it. The trade-off is "the system is free, but the service is self-reliant": no customer service when problems arise, drivers handle compatibility themselves, and data security is guaranteed by themselves.

So the first layer of answer is: are you choosing between "spending money to buy peace of mind" or "spending time to save money"? Now, let's lay out the differences across six dimensions. After reading this, you'll have your own judgment.

six dimensions: money, kits, Docker, photos, remote, security

first share the comparison chart I compiled, then pick the four most likely to get confused and expand on the details.

the four most common confusions, I'll share my experiences one by one

first point: access via external internet, which is the biggest gap between the two sides. Synology's QuickConnect is truly "zero configuration": just register an account, log in to the mobile app, and connect home, without needing to touch a router or a public IP. My mother-in-law's DS220+ was installed remotely by me from out of town, and I never visited her home the whole time. Feiniu doesn't have equivalents, so you have to do it yourself—my home has a router with DDNS plus port forwarding, and also has an IPv6 road. I wrote about which three routes to choose in the of remote access NAS. Those who know how to match it can get it done in ten minutes; those who don't get stuck all night. Just for this point, if you're afraid of hassle, you can just go for Synology.

second, photo backups, which are used the most often but are also the easiest to underestimate. Synology's Synology Photos is really good: accurate facial recognition, smooth timelines, stable two-way sync in phone albums. My child has taken over 20,000 photos in two years without any lag. Feiniu Album has a complete feature and framework—automatic backup, timeline, and shared albums. I have no major issues using it, but the accuracy of facial recognition is visibly lacking. My two kids' childhood photos often get mixed up. Photos are one of the most important data points for your NAS, so don't underestimate this area.

Third Rule: Docker and Gameplay Limit. to be honest, by early 2026, the experience running Docker on both sides is pretty much the same: Synology's Container Manager and Feiniu's Docker both use graphical interfaces to pull images and launch containers with a few clicks. I run Jellyfin on Synology and Jellyfin on Feiniu, and the setup process is no different. The real difference lies in the "beyond Docker" part: Synology has an official Virtual Machine Manager suite, so installing a Windows virtual machine is just a matter of clicking twice; Feiniu also has virtual machines, but their maturity is lacking. Also, my N100 has 16GB of RAM, so running a virtual machine with a dozen containers is no problem. The DS220+'s 2GB RAM is tough even to run Jellyfin code—the upper limit difference hardware freedom is much bigger than the software itself You can check out my Jellyfin for beginner Docker, which was installed entirely on Feiniu.

Fourth point: money. This is the most practical approach. I did the math for my two machines: DS220 + bare 2450, two 4T Cool Wolf 1,100 RMB, totaling just over 3,500; N100 main unit (including 16GB RAM and 2.5G Ethernet) costs 1220, power supply case and miscellaneous parts cost 200, system costs zero, and the drive was removed earlier, so it's fine if not included. With the same budget of 3,500, DIY routes can be configured with a machine with four drives plus 10 Mbps ports. But note, you can't just look at the entry price: Synology's residual value is ridiculously high. A DS220+ from two years ago can now sell for 1,700 or 1,000 yuan second-hand now, while a second-hand Feiniu PC is just a regular small PC price. This is how the holding cost should be calculated.

Who chooses Synology with their eyes closed? Don't hesitate

Based on my experience building a friend's PC, the following types of people will go straight to Synology—you won't regret choosing them:

• don't want to mess around at all. For those who want to "buy it and use it immediately, and never touch it for ten years,"
• family's main needs are photos and files. The most reliable Synology Photos
• is out of town, and they need to remotely maintain the NAS for their parents (QuickConnect is a unique advantage)
• the company's light office scenarios, you need invoices, after-sales service, and a backup

How to set up Synology for the first time you start your computer? I wrote an DS220+ beginner's , and just follow it for half an hour and you're done. There are also considerations for which type of stock to buy. I've calculated the accounts for two or four in this article—don't be like me, save first and then swap.

who smells better at flying cows, saving money and having a high ceiling

conversely, I directly recommend the following types of people:

• budget under 1,500, or if you happen to have an idle small PC or old computer
• like tinkering with Docker or virtual machines, need large memory and fast network ports
• are hardcore users who handle whole-home smart devices, downloaders, and multimedia libraries all in one
• Linux background, If something goes wrong, you can investigate it yourself

the first hurdle for Feiniu to get started was installing the system and hanging up the disk. The complete process for the N100 mini PC from scratch to usable—lsblk disk finding, formatting, and creating shared directories—I recorded the whole process in the about mounting the second hard drive in . Once you get there, you'll find the system's freedom is truly comfortable: add drives if you want, change hardware if you want, reinstall the system without worry.

my compromise: two units running in parallel, each doing its own

If you ask me if 'only children make choices'—okay, that's how I'm living now. The division of labor is clear: Synology is the "safe," while Feiniu is the "workbench" .

photos, home documents, Time Machine backups—all "lost to death" data—all on Synology. With dual-drive RAID1 mirroring, the machine hasn't restarted much in over two years, and it's as stable as a brick. Download the machine, Jellyfin testing, trying out new containers, all the random experiments on Feiniu. I've done the system reinstall once after crashing twice, and it recovered in half an hour—no regrets. After verifying the stable solution on Feiniu, consider whether to move to Synology for official use.

Another layer of

structure is backup for each other: two machines in different rooms, Feiniu synchronizes an incremental copy of Synology's photo catalog every night (rsync scheduled tasks), and Synology keeps a copy of the Finiu Docker configuration compressed package. If either machine fails completely, the core data will still be alive on the other. The hardest part of the 3-2-1 backup principle—'one off-site'—I managed to assemble it using two NAS. The idea was explained in detail in the of backups: a standalone user can get by with 'one NAS plus one external hard drive.'

so here's a practical tip: if your budget is sufficient, if you don't want to mess around, data is priceless—buy Synology's main DS224j or DS425+ with your eyes closed; Tight budget, tinkering, and wanting a ceiling—N100 mini PC plus Feiniu, just over 1,000 yuan to get a 3,000-yuan experience; Having enough budget and loving to tinker—learn from me, two units run in parallel, one for stability, one for comfort, and the money is the best value for it.
