yes, try freenas/truenas

It’ll work fine. A NAS is just a PC. Try Unraid if you want a user friendly UI. It costs money but it’s only a one off payment for a lifetime license, and they have a free trial.

Of course. Just put disks in and set up whatever remote filesystem and it’s a NAS.

A NAS is basically some software running on a computer, so you can use a desktop as that computer, ideally with a light operating system (for example, Linux in text only mode).

HOWEVER: desktops are designed for far higher computational loads than needed by a NAS, plus things like graphical user interfaces and direct connection of user peripherals such as mice, so even when idle they consume a lot more power than the kind of hardware used in a typical NAS.

Also the hardware in a good NAS will have things like extra higher speed connectors for HDDs/SDDs (such as SATA) rather than you having to use slower stuff like USB.

So keep in mind that a desktop as NAS will consume significantly more power than a dedicated NAS (as the latter will probably be running on something like an ARM and have a power source dimensioned for a couple of HDDs, not to run a dedicate graphics card like a desktop has) and probably won’t fit as many disks.

If you’re ok with having most disks be accessed a bit slower and USB3 work for you (and, for example, if your NAS is on 100 Mbit Ethernet, it’s the network that’s the slowest thing, not USB3) then it’s usually better to use an old notebook rather than desktop because notebooks were designed for running of batteries hence consume significantly less power.

Frankly I would advise against using an old desktop as NAS mainly because in a year or two of continued use you’ll have paid enough in extra electricity costs vs using a NAS to pay for a simple but decent dedicated NAS.

Another option is to use openmediavault.

I haven’t looked at truenas.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

Anything that can can provide storage attached to the network is a potential NAS. It doesn’t take a lot of power to just offer and store files. If you start getting into stuff like live transcoding or heavy encrypt/decrypt that’s a bit different matter.

Yes. Go look at TrueNAS Scale

Unraid as I understand it will do that

Saving for later

Just google perfect media server

My first NAS was an old desktop that I got for $300 running an FX-6300 and a GTX 550, I slapped a couple hard drives in there, installed Ubuntu, and made an SMB share.

I’d recommend installing TrueNAS Scale on a system rather than doing what I did in part due to it being so much better than what I was doing, but you could run it on a potato if you wanted.

Hell my latest NAS upgrade is going from a PowerEdge T610 (tower server from like 2010ish) running TrueNAS Scale to a normal desktop (from 2017) running TrueNAS Scale

If anything using normal desktop hardware makes servicing it easier than using old server hardware

Yes most hardware can be a server, but i recommend hdds thats made for nases!

You totally can, but since it will be on all day with 4 hdd look into wattages you want to live with. There are some small NUCs or Pi based NAS with low wattages. There is OpenMediaVault, FreeNAS/TrueNAS software to install

As others have said, you certainly can.

If your current system is a Windows PC then a super easy way to go about it is to purchase a product called Stablebit DrivePool which will allow you to combine multiple hard disks into one drive, and then do duplication of data you find important. Share that virtual drive as a Share that your other systems can see. DriePool is a super reliable product. Only downside other than the one time cost is that its redundancy is based on file duplication, which has the benefit that you can pull your drives out and use them elsewhere as any one file is always contained on a single drive, but unlike parity based solutions it’s super space inefficient to retain duplicate copies. It’s a tradeoff between simplicity and time to recover in a failure versus maximising disk use and reducing costs. Depending what your NAS is for, maybe you don’t need that redundancy but. You can also team it up with another product called SnapRaid (which is free) which can make your redundancy parity based.

I ran DrivePool for years on Windows and it’s a great product. Windows itself isn’t overly optimised for this use case, but as a predominately Mac household having access to Windows on a headless system was handy if I had to run the odd Windows only apps, so using Windows had its perks.

While Windows and a PC will cost more to operate, you’ll potentially be out well ahead if you don’t have to buy additional hardware. It’s likely worth running what you have into the ground rather than buying new hardware. There’s guides on some things you can do to optimise Windows too.

I’ve since moved to using UnRaid which is a paid product (one time purchase) designed specifically for NAS on your own PC. Great solution but I’d say that the barrier of entry is much higher than a Windows box. Still very versatile product. Moved to that as over time I’ve used a bit more Linux in my life, and I also had reduced need for Windows as the NAS OS.

Haven’t tried TrueNas but that’d be an alternative to UnRaid.
