I currently have a 10-year old off-the-shelf NAS (Synology) that needs replacing soon. I haven’t done much with it other than the simple things I mention later, so I still consider myself a novice when it comes to NAS, servers, and networking in general, but I’ve been reading a bit lately (which lead my to this sub). For a replacement I’m wondering whether to get another Synology, use an open source NAS/server OS, or just use a Windows PC. Windows is by far the OS I’m most comfortable with so I’m drawn to the final option. However, I regularly see articles and forum posts which frown upon the use Windows for NAS/server purposes even for simple home-use needs, although I can’t remember reading a good explanation of why. I’d be grateful for some explanations as to why Windows (desktop version) is a poor choice as an OS for a simple home NAS/server.
Some observations from me (please critique if any issues in my thinking):
- I initially assumed it was because Windows likely causes a high idle power consumption as its a large OS. But I recently measured the idle power consumption of a celeron-based mini PC running Windows and found it to be only 5W, which is lower than my Synology NAS when idle. It seems to me that any further power consumption savings that might be achieved by a smaller OS, or a more modern Synology, would be pretty negligible in terms of running costs.
- I can see a significant downside of Windows for DIY builds is the cost of Windows license. I wonder is this accounts for most of the critique of Windows? If I went the Windows route I wouldn’t do a DIY build. I would start with a PC which had a Windows OEM licence.
- My needs are very simple (although I think probably represent a majority of home user needs). I need device which is accessible 24/7 on my home network and 1) can provide SMB files shares, 2) act as a target for backing up other devices on home network, 3) run cloud backup software (to back itself up to an off-site backup location) and, 4) run a media server (such as Plex), 5) provide 1-drive redundancy via RAID or a RAID-like solution (such as Windows Storage Spaces). It seems to me Windows is fine for this and people who frown upon Windows for NAS/server usage probably have more advanced needs.
Never been a better time to try Linux. Ubuntu is pretty easy to get started with (download and setup a bootable USB, stick it and go) and ChatGPT is extremely good about walking you through any questions. You don’t even need to ask highly technical questions, just tell it your goal and your system.
“I just installed Ubuntu 22.04 on my computer and want to SSH into it from a Windows computer on my network, how do I do that?”
“I want to download a file from my Ubuntu command line, how do I do that?”
“I want to setup a share that both Windows and Linux computers can access over my network, how do I do that?”
“I have a github action runner provided by github that includes a run.sh file that needs to run constantly. I want to setup as a background service on my Ubuntu Linux computer so it will always be running as long as the computer is on, how can I do that?”
It will spit out every command line you need in what order, contents of a .service file, tell you how to monitor it, and so on. You can ask it what each line does, what the parameters mean, etc. It’s like having a mid-level sys admin at your fingertips. It will interpret any errors you get, and tell you how to fix them.
Perfect? Maybe not, but its close for a remarkable variety of tasks. It may be, and I’m not joking, 20 times more productive and time efficient than Google searches, reading stackoverflow posts, reading documentations/man pages and trying to decipher what you really need out of any of those sources.
I’m sure some are too paranoid to ask ChatGPT certain things for privacy reasons, and I would anonymize anything you paste in, probably just be a bit mindful of anything involving permissions (you can also ask what security risks exist doing something). Just normal ChatGP3.5 (free) is extremely knowledgeable about Linux CLI and administration along with common packages and apps you’d want to use.
For me, #1 is license costs. I’ve taken home some servers which would require me to buy 4+ windows server licenses because 16 physical cores is a number for entry-level servers at this point. For the cost of those licenses, I could almost buy a new server with a similar amount of cores every single year.
Second, the brand new filesystem, ReFS, (which needs licenses), has just about caught up to what ZFS had in 2005. The biggest omission is that 2005 ZFS could be your root filesystem. This is less important on *nix systems where your root can be tiny, but windows insists on storing tons of stuff on C, which still needs to be NTFS. ZFS also has 22 years of production testing and still has lots of development.
Third, I want to use containers, and windows uses a Linux VM to do that, so why not skip the middle man?
For server:
docker is linux in a jailed namespace (network, filesystem, process tree, etc jail)
Docker hosted on linux is efficient.
Docket hosted on anything else less so.Windows has more overhead, is more expensive, is less interesting/fun IMO, has poor data parity features, and has less of the homelab community’s attention than any purpose built Linux based home-lab OS. But it will definitely do the job with minimum effort from you.
There are a lot of good responses here that I won’t reiterate. I will say that, in my own personal and professional experience, Linux simply is a far better server OS than any Windows OS.
That said, use what works for you. If you are experienced and comfortable with Windows, and aren’t too keen on climbing the Linux learning curve, then by all means use Windows.
My only suggestion would be to use Windows Pro (for RDP), or find a Server Standard license for sale at less than retail.
Two reasons; gatekeeping and/or tribalism.
Honestly, you do you. Stick to what works with your workflow and use case.
However, given that you’re in r/homelab, it’s reasonable to think you’re open to learning new things. With that, Windows tended to not be as stable as Linux (hence the dominance of Linux in the server world).
Windows approach to drivers and software wasn’t as clean as Linux. Uninstalling software was not guaranteed to remove everything in Windows.
Windows license is another minus.
Plus, given that it isn’t open source, and given the dominance in desktop world, lots of viruses tend to target Windows, and we don’t get patches on a timely manner. Plus, there’s a history of patches breaking things in Windows.
Linux and Unix, tends to be simple and stable. Synology is a very good NAS, which combines the robustness of bsd with a fantastic GUI. I’d personally urge you to get another Synology or explore xpenology.
But barring that, your use case today is simple enough and if you think Windows is sufficient, go for it.
If you want to also get learning out of it, explore truenas scale. It’s based on Debian and is fantastic. You can also sideload proxmox on it for various VM and lxc magickery.
I’ve run a NAS from Windows Pro (and still do, unfortunately). I also have a server running TrueNAS scale and another running Linux Mint for NAS. My TrueNAS and Linux Mint servers are much better at reliability and uptime. The Windows server has reboots often and sometimes services don’t seem to launch before login. This could be due to configuration issues but it’s harder to find resources since very few people use it like this. I only have it for backing up family photos to Backblaze for $7 unlimited plan. If Backblaze offered this on Linux I’d leave in an instant. Also, ZFS is a lot better than storage spaces.
Once upon a time the home version of Windows didn’t support any level of RAID.
I’m not certain what it supports now but I think you can at least do mirroring and maybe it can do rotating-parity (RAID 5).SMB only (There is/was a way to make Windows do NFS, but it sucked.)
License cost. The desktop versions of windows (used to?) have a limit on concurrent SMB sessions in order to force users to buy the server version and pay for CALs. No idea how any of that works now.
NTFS is kind of a shitty filesystem.
Limited (native) backup options. No tape support, for example.
Management effectively requires GUI access.
No native way to mirror the OS drive in software. You need either a hardware RAID card (LSI, etc.) or that stupid Intel BIOS RAID thing.
These may or may not be issues for OP, but they are issues for many.
Windows bad. Linux good. BSD better.
For real though. Windows cost money, it uses a lot of resources. And Desktop Version is missing vital parts you might want to use on a windows server like Domain Controller, DHCP, Server, Web Server, Hyper-V. Etc.
Those reasons also have most running Limix or even BSD because they are pretty lightweight especially when used headless. Also as open source they are mostly free of cost. And when you virtualize on a free and open source Hypervisor like XCP-ng or Proxmox you can run way more smaller VMs than Windows VMs as they need more resources.
If you run only system resources, or task manager, or whatever windows is calling their resource manager these days to monitor CPU, right next to a headless debian server running only htop you will straight up see the answer to your question.
That, is overhead.
Personally, unless I need Active Directory, I actively avoid MS Server. One of the biggest issues for me, is the lack of Docker support. If I have to run WSL or a VM for Docker support, then I’d rather just run Linux and cut the middleman.
Short answer: desktop versions are tuned for application performance, especially foreground vs. background, while server versions are tuned for, well, being used as a server, multitasking being less performance-penalizing for background applications (like server daemons/servelets) and of course greater uptime.
There’s also much more bloat on the desktop side, as it’s targeting consumers and not IT.
Windows 10 starts to behave weirdly after like 60 days of uptime. USB devices are not detected, drivers randomly restart, …
Linux just runs…
Also Win 10 installs updates more or less randomly…
