    i love ozads

    • ChickenDinner123 on 20/12/2021 - 10:39

      This is a good value for a general use PC. Perfect for parents and for normal everyday use.

  • krouton24 on 20/12/2021 - 10:34

    Have one of these with 16Gb of RAM (4 x mismatched 4Gb) and SSD running Win11 and VMWare running MacOS. Running 4K screen at 60Hz through DP.

    Very surprised by how well the 4th Gen i5 handle it. CPU sits between 37°C and 50°C.

    I'm not gaming though.

    Having said that, you'll get a better price from Gumtree.

    • slackme on 20/12/2021 - 11:23

      Does it support Windows 11?

        Not officially. Use Rufus to create a bootable USB without the min requirement checks.

        Getting all the updates and running faster than Win10

  • Harryw on 20/12/2021 - 11:24

    Do you have any other PCs with Win 11?

  • knwebuse on 20/12/2021 - 11:44

    Can it be upgraded to WIn11 ?

      Yes if you install Win11 via USB it skips all the checks. It'll receive updates too.

      • knwebuse on 20/12/2021 - 13:17

        Thanks for confirming one way to upgrade.
        Is the Intel Core i5 4570 processor too old to pass the check ?

        • Clear on 20/12/2021 - 14:04

          Yeah select 7th gen and 8th gen or above are the minimum requirements.

  • rusteh on 20/12/2021 - 12:56

    I want something to run a bit of unRAID and a few containers (Hass.io, sazbd etc) nothing hardcore. Don't really care about 4k transcode for Plex I don't think. Have android tv with native 4k playback I believe. Would this suit?

    • thrillho556 on 20/12/2021 - 13:02

      I have this machine and have been running an OMV server with Plex and a bunch of other docker containers smoothly for years! Would definitely recommend. Haven't tried 4K transcodes but it does 1080p transcoding pretty well with multiple streams

      • hollykryten on 20/12/2021 - 13:09

        It might be able to transcode 4K video through the Plex hardware accelerated streaming with Intel Quick Sync Video. Minimum spec says it supports 2nd gen Intel core CPU or later. This is a 4th gen Intel core CPU. But you also need an active Plex Pass subscription. It will probably only be able to support one 4K stream or maybe a second.

        • drinkin-beer on 20/12/2021 - 13:31

          Don't quote me on it but pretty sure earlier quick sync is nowhere near as good as from 7th gen onwards. Not saying this cant transcode 4k but I wouldn't buy it expecting it to.

    • MasterScythe on 20/12/2021 - 14:15

      Just a note; UnRaid is great for a media server, because a bit flip here or there over time in a media file (other than photos) won't usually cause any appreciable damage.

      However, it offers no data\block level protection, so if you plan to use it for actual NAS duties, outside of media, You're better off exploring other options like ZFS or BTRFS based solutions.

      I think LTT made UnRaid popular, personally; and they did NOT do a good job of expaining the risks, and the extra work required to self-replace any damaged data from another backup that's important to you.

      It's also not free…. If it's a media server; and you add files rarely; consider something like SnapRaid.
      Proper block level protection, free, multi-platform, just schedule based, not real-time is all.
      But I don't need more than 24hr updating protection for a media server anyway.

      • Quantum on 20/12/2021 - 17:15

        hol up, you mean to say Unraid offers no data protection? And that a bit flips can happen without detection?
        I am pretty sure it has parity drive(s) specifically to detect data (bit) errors…

        Unraid is a bit like Apple in some regards, you pay more, but it just works. Some people like to trade money for time I guess.
        I do agree it is more of an Archive/data hording NAS than a high speed "scratch space" NAS. (Different NAS solutions definitely have different goals)

        Would it be fair to say unless you like to fiddle and get under the hood, and you think managing your NAS and its OS is fun, you are better off sticking to a paid solution like Unraid?

        • MasterScythe on 20/12/2021 - 19:15

          hol up, you mean to say Unraid offers no data protection? And that a bit flips can happen without detection?

          Correct, it does not checksum the data at a block level whatsoever.

          I am pretty sure it has parity drive(s) specifically to detect data (bit) errors…

          I'm absolutely certain you're mistaken. One very recent option is to choose BTRFS as the top level file system on each drive, which will ALERT a user to an error
          However, as each disk is a BTRFS drive, not a BTRFS Storage cluster, recovery is not possible. It's Alert Only, and that feature is 'community driven' and only an option via command line, it's not really an UnRaid feature.

          Unraid is a bit like Apple in some regards, you pay more, but it just works. Some people like to trade money for time I guess.

          Other way around, UnRaid has certain features that work well, but if you're using it for data storage, then its on you to manually checksum and backup your data, in case of bit flips or write errors.

          I do agree it is more of an Archive/data hording NAS than a high speed "scratch space" NAS. (Different NAS solutions definitely have different goals)

          No, we disagree. Without block level checksums it's TERRIBLE for Archive storage, because there's no way to recover from a bit flip or silent sector errors.

          Would it be fair to say unless you like to fiddle and get under the hood, and you think managing your NAS and its OS is fun, you are better off sticking to a paid solution like Unraid?

          There are better solutions, which are designed around protecting billions of dollars. The ZFS filesystem was built for bank databases, where an error could lose millions, it's foolproof, and worlds better, and MUCH harder to make an error, than any 'unraid' solution.

          If you want portable 'any disk size' archival storage, you'd use SnapRAID.

          • Quantum on 20/12/2021 - 22:12

            @MasterScythe: Thanks for taking the time for the informative reply & helpful side note.

            I'm absolutely certain you're mistaken.

            I don't think so, I will stand by the fact that Unraid can detect a single bit error. Technically that is correct, for what is worth anyway. That is its principle of operation. However I will concede it will take a month to tell you about it, you will have no idea which drive or file caused it, and no easy fix for it. The more drives there are the worse the problem is. So it is almost useless. Even worse users can "repair" parity, in other words accept the error and do nothing about it. But hey on the plus, you would be able to replace a totally failed or missing drive. Flipped bits and all.

            Good marketing trumps good technology? Has Unraid and LTT done a hatchet job on everybody?

            So does that mean Unraid is only good for data you are prepared to accept corruption in? (like media which can disguise/hide mirror errors in most cases) Is it a bad NAS solution? Or is it totally irreverent if you are not running ECC RAM?

            • MasterScythe on 20/12/2021 - 22:52

              @Quantum:

              I don't think so

              I know so.

              I will stand by the fact that Unraid can detect a single bit error. Technically that is correct, for what is worth anyway. That is its principle of operation.

              If you're that confident, please contact the developer and teach him how.
              Many of us contribute code to this project, and he's resistant to 'new ideas' on bitrot protection.
              Because so far none of the devs have figured out a way to impliment it.

              However I will concede it will take a month to tell you about it, you will have no idea which drive or file caused it, and no easy fix for it. The more drives there are the worse the problem is. So it is almost useless.

              Why? I dont understand your claims.
              Can you elaborate?
              A parity mismatch is instantaneous… why would there be a delay?

              you will have no idea which drive or file caused it

              No idea which file, correct, because errors are 'in a file' only in the eyes of a user. In an array, they're in a block; it could be 1 billionth of a file, or 2 files in the case of shingled storage. There's no block level checksum, So it can't know.

              However, drive should be instantaneous.
              It should be able to see 'the math on this drive is wrong' but there is probably a googleplex worth of ways to make the math 'work out'; it has no idea which method is correct (ergo, which block to repair).

              What do you envisage would make disk detection slow though?

              Even worse users can "repair" parity, in other words accept the error and do nothing about it. But hey on the plus, you would be able to replace a totally failed or missing drive. Flipped bits and all.

              This totally contradicts what you've claimed above. If it's able to "idenify a single bit error", why not flip that bit?
              All it can do is know there is AN error, it doesn't know if it's single, multi, or whole partition.

              But hey on the plus, you would be able to replace a totally failed or missing drive. Flipped bits and all.

              Correct, and that's its value.
              Being able to have drive level redundancy for uptime.

              Good marketing trumps good technology? Has Unraid and LTT done a hatchet job on everybody?

              No, everybody is just incapable of assessing technology these days.
              Their marketing doesn't lie, and LTT's use case is PERFECT for UnRaid.

              They're working with video files, many which are ever-changing (until release); you can flip a LOT of bits in a video file before it becomes humanly noticable; and this is why it's popular for a Plex server also.
              Just storing video? Thats great, 100 flipped bits over 10TB? You'll probably never know.

              But flip 1 bit in a JPEG, and it's corrupted.
              https://upload.wikimedia.org/wikipedia/commons/1/1a/Bitrot_i…

              Their use case is PERFECT, but you'll notice they run zero UnRaid servers anymore and have moved to ZFS solutions for exactly these reasons.

              So does that mean Unraid is only good for data you are prepared to accept corruption in?

              Yup! And it never claimed to be anything else.
              It's a disk pooling solution, with disk level protection, and nothing more (on a storage level).
              Linux MDADM, Windows RAID, and traditional 'Raid Cards' form old servers are in the same boat.
              It's not possible without block level checksums to know what a block is meant to contain, especially if it's literally a piece of a fragmented file, for example.

              That is literally why ATOMIC COW file systems have become popular.

              https://arstechnica.com/information-technology/2014/01/bitro…

              Is it a bad NAS solution?

              If your NAS contains data that can't handle bit errors, yes, it's a very bad solution.

              Or is it totally irreverent if you are not running ECC RAM?

              No, this is where a good file system is key. I'll use ZFS as the example, because it's king of this trickery.
              ECC RAM does indeed help to assure that the initial write went without error.

              For this example, lets assume that the file was written correctly;
              next comes the magic of block level checksums.

              When reading a file, there is a comparison between the checksum stored with the file and the checksum calculated on the file; and if they disagree, then the checksum stored on the blocks, making up that file.

              The clever part here, is that ZFS is smart enough to correct the flipped bits, on the fly; and the user requesting the file, will get a 'temp file' (stored in the ARC cache) which is 'healed'. ZFS however, will NOT resilver (heal) the file, UNTIL you run a scrub.

              Upon running a scrub, it will correct these errors, and assuming you snapshot nightly, you can go and test the files to make sure they're OK.

              But, what if your RAM is bad? Well, here is where ZFS is smart.
              If your ram is spitting errors, the new block level checksums WONT match the original checksum, and it will try again.
              If it fails multiple times, the file system will instead serve you the 'corrupted' file, storing a log of the 'unrecoverable' file for you to look at.
              You can then force the repair if it IS broken, via corrupted metadata or some such (after running memtest), or tell it to accept the 'error' and recreate the checksum on that file.

              NOW

              There is one theoretical risk of Non ECC RAM with ZFS, but nobody has known to have actually had it happen.
              IF you had 'Evil Ram', and it was able to have the EXACT same bit pattern, land in the EXACT same faulty memory addresses?
              Then you'd have the multiple checks passing as correct, out of. pure. dumb. luck.
              In that freak instance, it could 'heal' a healthy file with junk data.
              The odds of this are in the ether of imagination, but it's a theory that can, arguably, happen.

              BUT, in that instance, thats why you have snapshots, right? Thats why you run an ATOMIC COW file system.
              200MB 'backing up' tens of terrabytes? Yes please.
              Just roll back that file to before this error occurred, and bam, you're back and working again.

              It's an amazing filesystem.

              BTRFS does some very similar things, but its younger; and ReFS is heading that way (but is a baby so far, with almost no features enabled outside basic checksuming… and Microsoft is gatekeeping its use for some reason…).

              Basically, just run ECC ram, it's cheap and easy if your CPU and chipset support it….
              But if they DON'T? You're still WORLDS better using a filesystem like ZFS than not using it; because it has safetys built in for that scenario.

              TLDR?

              So does that mean Unraid is only good for data you are prepared to accept corruption in?

              Yes.

              It's great for a media server, or even a true backup server (because you still have the originals, right?) But for archival storage, or single-point-backups of changing data? It's a terrible idea.

              It exists to pool drives, and enable uptime via disk level redundancy. It's never claimed more, and it does that admirably.
              It should never be recommended to 'new users' who aren't used to manually monitoring their own file integrity (if that matters to them).
              It's just…. too much work.

              • Russ on 21/12/2021 - 18:26

                @MasterScythe: All of the methods of error correction discussed above require either multiple drives (e.g. RAID) or data duplication (e.g. mirroring).

                While this permits the recovery of a file where one of the drives/copies has every bit corrupted, it's overkill for bit rot.

                Flash memory chips, such as the MT29F256G08A, use simple two-dimensional parity for error correction, using only 448 bytes per 8Kbytes of data. This solves most bit rot problems. And that's using a very simple algorithm designed for simple hardware decoding, and much better error-correction algorithms are readily available.

                Do you know of any file systems or file utilities that use this approach to making files repairable? Increasing the size of a file by 5% is preferable to mirroring in many situations.

                  Yes. The RAR Archive container, utilising Recovery Records.
                  https://www.winrar-france.fr/winrar_instructions_for_use/sou…
                  It's what I use to protect archive backups stored on standalone disks.

                  You're also very correct that it requires some form of parity disk; a 5 drive RaidZ1 loses 20% of it's space, not 5%, but you gain read\write speed, and resilience against downtime due to disk failure also.

                  So yes, if you're looking for basic protection against bitflips, then a 1% recovery record on a RAR file is already massively beyond that; at 5% it's (realistically) unbreakable.

                  It does however, sacrifice ease of access; though this CAN be worked around by using FUSE level filesystems; like rar2fs
                  https://github.com/hasse69/rar2fs
                  And treating said 5% 'protected' RAR as a mounted drive.

                    @MasterScythe: Thanks! I had looked into Parchive, which was originally for reliably storing data on CDs and DVDs, back when they were popular. But the overview of what it does isn't clear about how much extra space is needed. Your method is much more understandable, and comes with file compression too!

                      @Russ: Yeah, people overlook it because rar is closed source.

                      But after all these years, no weakness has been found in it, outside of being vulnerable to brute force password guess attacks.

                      The fact that the command line version is free, means I can use it to backup anything, anywhere :)

                      I really advise skimming the actual RAR manual, its way more powerful than most know.

                      Overkill your backup with like 10% recovery, and never worry again :)

      No, these are fine.

      If, like most 'nanas', EVERYTHING she does is online, or in an office product;
      It's worth considering using Linux Mint on it, for 'nanna duties' because she literally can't infect or break it.
      - It still has a 'start menu'.
      - It mounts anything you plug in, to the desktop (like a Mac) so no need to go 'looking for drive letters'.
      - It ships with Firefox.
      - It ships with OpenOffice\LibreOffice (totally Office365 compatible).

      It. Just. Works.

      And probably most important for an 'old person', it never 'prompts you' for ANYTHING.
      There's no risk of tech-panic\tech-freeze where older people just STOP using the machine, because it asked them something they don't know.

      I've supported retirement homes and disability centres for a long while; and being able to say "Virus proof, 'break' proof (they're not root), and no unexpected questions" puts people at total ease.

      My parents went from 'Should I click this?' to 'Haha, someone tried to scam us, but we're smarter than that now!' within DAYS of being told there's now zero risk of 'breaking' their PC.

      Not to mention, that because Cinamon (Mints desktop) is so windows inspired, ALL the habits they pick up, are totally transferrable.
      Still a corner menu, still 90%+ of the same terms for settings, same app names…. It just makes sense.

      You don't have to.
      I'm not the boss of you :P
      But it does make sense to give the Live CD\USB a try for yourself, and see what I mean.
      Right tool for the right job.

      The only negative I can think of is that its a true dead end system.

      There's nothing in here you could 'upgrade' from the 2nd hand market, and make it appreciably better.

      So, while a $300 ddr4 based system, might have a higher end CPU and the ability to add current(ish) gen ram, in a years time; this is 'end game'.

      But for the money? Well, thats why its listed as a bargain :)
