10 Reasons Why You Should Store Your Data on a FreeNAS Box

Yusuf Limalia 11-07-2017

Your data is invaluable and strictly confidential. But which company should you entrust your sensitive data to? Which payment tier should you surrender your hard earned cash? Maybe you want to access your media across all your devices anywhere in the world?


People are quite outspoken on this subject, and with the choices out there, some, if not all of them could be confusing.

Operating systems like unRAID have similar functional flexibility, and unRAID is excellent for personal and small business use. However, there is a cost attached to how many drives you can install. Even the file system that unRAID chooses is vastly different to that of FreeNAS.

The least flexible of the options will be a store bought one. Alternative network storage solutions like QNAP and Synology might be easier to setup. However the cost attached to them, along with limited flexibility, isn’t the same as FreeNAS. Here’s why.

1. FreeNAS Is Free

The absolute best price to pay for anything. Although it’s name is derived from the base operating system it’s powered by (FreeBSD), the current stable version, which is FreeNAS 11, is fully featured and free! Both for people in a home or corporate environment setting. Your wallet will love you for this.


2. Mature Operating System

While being a subjective word, software needs to to meet certain criteria in order for it to be deemed mature. FreeNAS traces its roots back to 2005 and has since been downloaded over nine million times! The evolution of FreeNAS has transformed it into one of the most secure, reliable, actively maintained and globally field-proven NAS operating systems you can get your hands on.

3. Re-Purpose Old Hardware

Do you know that old PC that is in your garage which you’ve promised to get rid of for as long as you can remember? Why not breathe some new life into it. FreeNAS will run on just about anything. Granted you may not be able to simultaneously stream 4K content to your entire neighborhood. But if you wanted a simple, secure file server and or backup server.

With some elbow grease and determination, you could save yourself from the woeful scorn of your unloved old PC. The only items you should definitely buy brand new are the drives. Relative to other components hard drives degrade much quicker.

4. Enterprise Grade Storage

At this point you may ask: “But obviously I need an expensive RAID controller for this level of storage?” Absolutely, positively not!

FreeNAS uses the ZFS file system, which doesn’t suffer from most, if not all of the issues or limitations that legacy file systems and hardware RAID controllers have. Even in the event that your motherboard dies, you should be able to plug in your drives to another machine running FreeNAS and import your volumes.

There are ZFS options for creating striped drives, mirrored drives and even a disk array with two parity drives. Which means your array will have to suffer three drives failing outright before you have a catastrophic failure. The flexibility that FreeNAS offers combined with the ZFS implementation makes setups from home all the way up to corporate a possibility. Did I mention that there is no restriction on how much storage you could add?

5. Secure and Private Personal Cloud Store

You will never have to pay for a cloud storage subscription again or run the risk of your data leaking How Secure Is Your Company's Cloud Storage? Check out this image that breaks down all kinds of cloud storage threats, some the of issues facing cloud owners, and more. Read More because some malicious, hoodie-wearing millennial has hacked your cloud storage provider and now has a copy of your passport and social security details.

ownCloud will allow you to share your files, contacts, calendars and more on any device. Your data will be stored only on your FreeNAS box and any device you, and only you give access to.

6. The Ultimate Backup and Media Server

Loss of data can be a catastrophic experience, especially if you formatted your five-year-old USB stick with your precious family photos and the only copy of that hysterical video where you dressed up your dog as your minion for Halloween. Even in the unfortunate events like theft or natural disasters, your data is invaluable.


FreeNAS has native support for replication, snapshots and rsync as well as extended support for services such as CrashPlan and even Amazon S3. Got a Mac?

If you’re storing all your media on your NAS it makes sense for your NAS to serve up that media to your network. Plex is one of those applications that you can’t imagine life without. After adding Plex to your FreeNAS box it now transforms your enterprise grade storage solution into a bad ass media server. With support for pretty much any smart device with a screen or HDMI port.

7. Virtualization

With the current version of FreeNAS (FreeNAS 11) comes a hypervisor. This means that you can spin up as many instances of Windows or Linux right on your FreeNAS server as your hardware permits. This makes cases like testing out a new operating system or creating tiny virtual machines that have a specific purpose a cinch!

The boffins over at FreeNAS have also announced that Docker will be supported in the next release, which opens up your FreeNAS box to the world’s leading software container platform. Be sure to check that your hardware supports virtualisation 7 Practical Reasons to Start Using a Virtual Machine What are virtual machines used for? Here are some practical benefits and uses for virtual machines that you can try right now. Read More  to take advantage of these features.

8. Who Needs Off-the-Shelf? Make It Your Own!

Everything from which components you use, to how you implement is completely up to you. This makes the upgrade and maintenance path for your appliance more supported than buying an off the shelf solution like what Synology or QNAP offer.

The sense of accomplishment you get for building your own device, that is more cost effective, reliable and feature rich is addictive!

9. Rock Solid, Set and Forget

Once you have your FreeNAS box setup, it will only need attention from you in the event of a hardware fault or necessary update. The dashboard does have telemetry built in so you have the option of keeping a watchful eye on your disk, network or CPU usage.

Alternatively you could use the built-in notifications to email you in the event that one of your drives has failed, and if you don’t replace it soon, your entire GIF collection of cats is going to be lost!

10. Community Is Awesome

Another indication of software maturity, is in the activeness of it’s community. The FreeNAS forum is a plethora of knowledge, not just on FreeNAS, but many experts in the fields of security, software development, analysis, and even people that are brand new to the Linux community 4 Helpful Communities for New Linux Users You might be wondering, "What do I do now?" If you're at that point, then it's time you joined a Linux community — even if you only intend to lurk. Read More take part in the conversations.

You will rarely, if not ever, come across an instance where someone hasn’t asked the question you need an answer for, or someone will not be able to answer. The FreeNAS community over and above all the bells and whistles of the operating system make its adoption as smooth as swimming in a pool filled with double cream.

      File systems are different. Both are suited for different purposes. Media server? UnRAID every day. Something that requires high-performance I/O (perhaps such as a database), FreeNAS.

      I prefer UnRAID for my general storage / Plex usage.

  2. psypher

    I'm, everything you mentioned as coming soon is already available in unRaid which blows FreeNAS out of the water.

    You should also note that FreeNAS has telemetry enabled out of the box sending your boxes private information as well as your IP to the developers.

    I wouldn't have noticed if I didn't have a "block all out" firewall.

    • Chris Moore
      January 7, 2018 at 6:28 am

      This is on by default, but it is easily disabled by unchecking a box that is helpfully labeled, "Enable automatic upload of kernel crash dumps and daily telemetry:"
      The data is not really sensitive and is used by the development team to identify and correct problems. If you are not interested in sharing to make the Free product beter, just uncheck the box.

      • Nope
        January 12, 2018 at 4:51 pm

        You fail to see the problem here, which is that you talk about security, privacy and respect and then advocate for a product that breaks this fundamental trust by having to "opt-out" from telemetry.

        Either you respect privacy and send nothing, or you don't. There is no middle ground.

        • Chris Moore
          January 12, 2018 at 5:10 pm

          I am not saying there is a middle ground, but you are taking a very extreme view. The telemetry you speak of is only even considered private by some people that are very paranoid. Additionally, the feature is intended to improve the system, not observe your personal data, which they have no access to.
          Regardless, this will likely be changed in the next version because it has been reported as a bug.

        • Nope
          June 7, 2018 at 4:10 am

          Note, I wanted to reply to this old post of mine as FreeNAS is now technically illegal in Europe due to GDPR being implemented as a law.

          FreeNAS does not explicitly inform the user about enabling/disabling the telemetry nor does it single out the data being sent to their servers.

          If someone were to be a nasty person, they could report them to the authorities.

        • Rjkbj
          June 9, 2018 at 1:30 am

      What's the model number of your device let me double check

    • Chris Moore
      January 7, 2018 at 6:24 am

      No, FreeNAS can't reliably monitor the health of drives through a hardware RAID controller. It needs direct connectivity to the drives. Also, a USB interface is not very reliable for drive connectivity. The community recommendation is to use a SATA or SAS connection.

    I spent months going over probably 10 different free and paid "roll-your-own-NAS" solutions, and FreeNAS, NAS4Free, and OpenMediaVault is what I narrowed my choices down to. I ultimately went with OpenMediaVault because it would work best on the free hardware I had laying around in my basement unused. FreeNAS requires a minimum of 8GB of RAM to run correctly with ZFS. ZFS in general is very resource hungry. I ended up installing the OMV extras package, and setup SnapRAID and MergerFS to create a sort of software RAID that is more flexible. Basically, SnapRAID uses one of the drives to store the parity info in case a drive goes offline, and stores a log file on each of the drives to check against. This is the redundancy part of the equation. MergerFS or other pooled volume managers basically takes several drives and creates a single unified mount point to dump data to, and distributes data across the drives as it sees fit. The beauty of this solution is that I can lose any single drive in the array, and replace the drive easily. I am also not relying on Linux Volume Management for a software RAID solution, so in case something happens to the OS, or the array gets destroyed or corrupted, all my files are stored on each drive as a normal EXT3/4 partition, so I can pull any of the drives out of the array and read the files on any other Linux system without any problems. I just like the flexibility of this setup. I think for home use, it has a lot of advantages for data that doesn't see a lot of changes on a regular basis (media files for example, are pretty static). NAS4Free is a fork of the original FreeNAS project, which works with older hardware as well. A good second choice for sure. FreeNAS is definitely more targeted towards those with more robust hardware and enterprise use however. But it's definitely a good solution.

    • Yusuf Limalia
      July 14, 2017 at 7:25 am

      You've definitely done your research! I can see how not relying on LVM, and the ability to pull a drive out and read it on another machine can be really useful in quite a few use cases.
      You're quite right about FreeNAS needed more RAM than the other solutions out there. FreeNAS' implementation of ZFS uses all that RAM for caching and some of the really cool features of ZFS.
      Doesn't help that there is currently a RAM shortage globally and prices have gone up slightly!

    • Joseph J. Pollock
      July 19, 2017 at 8:42 am

      Thanks for the great post. I am very wary of zfs/raid for that reason. I will look at OpenMediaVault right after I post this.

    • Joseph J. Pollock
      July 19, 2017 at 8:58 am

      I have been trying to figure out NAS for some time with limited success.

      I have two major concerns which are not addressed by this article (which is good as far as it goes.)

      1) I see Freenas saying you need a bunch of iron (expensive) to run a NAS. At the same time, I see NAS products built with atom processors.

      I want to store a bunch of mostly static stuff which I will access once in awhile. I probably don't need to stream anything. I probably also want to use the NAS for daily backups from my notebooks using rsync. So my bandwidth should be really low.

      I can't imaging needing 8GB ram or lots of cores.
      So how much iron do I really need?

      2) I am a long time Linux user, but I know very little about security.

      How secure will my NAS be and just how much do I have to do and know to keep it that way (beyond just installing OS updates.)?

      • Yusuf Limalia
        July 19, 2017 at 9:17 am

        Hi Joseph! Really good questions!

        1) The difference between FreeNAS' and the Atom processor bunch is that FreeNAS doesn't require a hardware RAID controller. Infact FreeNAS works better if it gets direct access to your drives. FreeNAS opts to store all of this RAID config and ZFS in RAM. That's the reason you need 8GB as a minimum. Subjectively if you had to ask me which i'd rather replace between RAM and a RAID controller (in the event one goes bad), I'd choose to replace the RAM any day of the week. I found this link to their site really helpful in explaining some of the design considerations you will need to make:

        2) If by security you mean getting ssh access to your box:
        I have my FreeNAS box only accessible via SSH-Private / Public key pair.

        if you meant people getting access to your shares:
        This ultimately is up to how you setup your share and file permissions.

        Any plugins you install (currently) will be in Jails. So they are completely segregated from your Tank of data, and will only get access to what you give them access to. I say currently here because Docker will be coming as an option in the next release. I prefer them over Jails.

        You being a long time Linux user, I highly doubt you will have any trouble here. As long as you're on a STABLE release of the OS, you should be good. I, like you believe that you have to suspect every loophole and treat all mediums as untrusted. Out of the box however, the only vulnerabilities will be the ones you introduce.

        Fortunately the community is so knowledgeable, and tutorials normally have caveats on security decisions you need to make when implementing any addons to the base system.

        Hope this helps!

    I believe at this point mentioning FreeNAS 11 and virtualization support is aggressive when also mentioning a Mature OS and Rock Solid. Given the history of FreeNAS Corral; version 11 will receive a wide berth for the time being.

    • Yusuf Limalia
      July 14, 2017 at 7:27 am

      I was really disappointed in what happened with Corral. Hopefully they've learnt a lot from it. I surely did with my early adoption! I normally never take the plunge until after a few months. The UI and Docker support was just too much for me to miss out on. Lesson well learnt!

      Good shout on reusing old servers. I've seen Google ones on sale on eBay as well. AS long as you're willing to put up with the noise and probably paying a pretty penny if your power supply goes. At least you will know the hardware is more geared towards 24/7 operation!

      Thanks Bobby.
      #6 actually mentions replication, crashplan, and Amazon S3. Both could be used for off site backup.
      Personally I use crashplan, which is like $7 / month for unlimited space. I also keep very important information on S3, so restoring is really quick.

      Hopefully my house doesn't burn down, but if it does my data is safe on FreeNAS thanks to the integrations it offers.

      • Ellis
        December 1, 2018 at 8:55 am

    I'm glad yoou're so enthusiastic about running your own server and thanks for the write-up. BUT...

    Very relative term! Linux has been around since the mid-1990s and still is considered 'not ready for prime time' by many.

    "3. Re-Purpose Old Hardware"

      2. Mature Operating System
      >> "Very relative term! Linux has been around since the mid-1990s"

      FreeNAS is built on FreeBSD, which has been around since 1993. There's that...

      >> "and still is considered 'not ready for prime time' by many."

      Says who?

      I actually administrate Linux (RHEL, CentOS, Debian) in the real world enterprise, so I don't know where you're getting that information.

      3. Re-Purpose Old Hardware
      >> "That old PC in the garage probably is an i586 or i686 so will not be able to handle modern SATA III drives. Also the mobo will probably max out at 2 GB RAM making your server as slow as molasses in February."

      Obviously you read up on what FreeNAS requires to run before attempting to deploy it on old hardware.

      Minimum Hardware Requirements:
      Multicore 64-bit* processor (Intel strongly recommended)
      8GB* Boot Drive (USB Flash Drive suffices)
      8GB* RAM
      At least 1 direct attached disk (Hardware RAID strongly discouraged)
      One physical network port

      People consider 2nd Gen i5/i7 to be old these days, and it will run FreeNAS just fine.

      5. Secure and Private Personal Cloud Store
      >> "That malicious, hoodie-wearing millennial can as easily hack your personal cloud as he can a commercial one."

      Sure, there are vulnerabilities for everything.

    Just remember a NAS is not a backup solution! I tell everyone this and then let them know to make a secondary offline backup of the most critical data that is stored on your NAS. Just because it has drive redundancy doesn't mean your protected from everything. Anything can happen, and more often then not its the RAID setups that end up failing more than single drive setups. Ive seen it happen to enough people that this should be a statement made at the beginning of any article that talks about NAS enclosures.
