Synology DiskStation DS1821+ (8-Bay NAS) $1,423.75 Delivered ($0 VIC/SYD/ADL C&C/in-Store) + Surcharge @ Centre Com


Fantastic price, cheapest it's been for over six months on the Synology 8 Bay Synology DS1821+. For anyone that missed the $1399 deal last year, this is the best price I've seen since; apparently it was rumoured there was a price increase on the units after the 2023 sale, so now when adding the coupon (CHOPCHOP15) the price drops to $1423.75 which is great and even cheaper that the $1449 deal in January 2024.

Surcharges: 1.2% Card & PayPal, 2% AmEx.
Free shipping excludes WA, NT & remote areas.

I picked one up this morning, seems to have stock online and in variety of store locations.

  • Can these Synos do Plex with no issues? Because I have 918 and it has intel chip with built in transcoder.

    • +11

      The DS1821+'s CPU does not support hardware transcoding, so keep your DS918+ :)

    • +5

      These Synology NAS have a Ryzen CPU - so unfortunately are not as amazing as the Synology x20 series (220+ 420+ 720+ 920+, 1520+) which house the Celeron J4125 (720+, 920+, 1520+) or J4025 (220+ and 420+) when it comes to the transcoding factor.

      However the 1821+ is still an incredible buy if you want the space in one box. (Edit; I have a 920+ with DX517 which I use for Plex; I got the 1821 to run along side these for data only at this stage).

      • Plex can also keep optimised versions so depending on your needs you can plan ahead. But no for Ad hog streaming it’s probably not a good choice.

    • Got a DS1821+, running Plex without issue.

      • +4

        Yes… when hardware-accelerated transcoding/encoding/decoding is not required. If you only stream locally and has smooth home network, likely you don't really need to transcode your videos for playback, then you'll be Plexing/Jellyfining/Embying no issue.

    • +1

      What do you need to transcode in 2024?

        • -6

          Time to upgrade your playback device.

          • +4

            @gadgetguy: You can also transcode to save bandwidth - my device can handle it fine but often crap hotel wifi etc can't.

        • Really!? My 9yo TV with a $0.20 Mediatek SoC will handle 4k 265.
          In 2024 really the only codec for tc is AV1.

      • +2

        Bucket loads. Most modern devices when playing remotely will still automatically transcode down to a lower bitrate and will only play natively if you manually select original quality.

          • +5

            @gadgetguy: Yeah, we get it - you love direct streaming. Cool. But there's plenty of use cases for transcoding. For instance, streaming to limited bandwidth devices or streaming to multiple devices at once (especially remote devices over residential internet connections).

          • +3

            @gadgetguy: Sure, i'll just get everyone that uses my plex remotely to somehow plug an nvidia shield into their smartphones and tablets….

          • +4

            @gadgetguy: And when you max upload bandwidth for remote users ?

          • +2

            @gadgetguy: For local playback with one device… sure… but if you stream remotely from outside your home while travelling or have a household of devices that are accessing the Plex library that are not Shields… i.e., tablets, laptops, phones etc… you'll quickly learn how important transcoding can be.

            • -2

              @timjohns: Some of the excuses used here for transcoding are downright broken.

              Laptop? Tablet? Phone?
              You mean your devices can not handle even vaguely modern codecs?
              Running Plex and jellyfin both to multiple 5-10 year old clients here with no issues.

              Yes there is a use case for transcoding but 80% of what prime are saying above is not a valid use case.
              Remote streaming over low bandwidth is about the only valid excuse.

              All the other devices people are mentioning after probably just not setup correctly (my jellyfin playback on mobile works fine after allowing the client to use external codec) or are so ancient your need to replace them.

      • Depends on how many clients you sharing with - and how many remote users.

    • Just plug in a portable hard drive and there’s your Plex storage sorted, son.

    • do Plex with no issues?

      Get the codecs aligned and you won't need to 'transcode'.

  • +9

    i'd never go with synology again after my 1815+, the os restricts the brand of drives and has a secret whitelist in it which gimps the status monitoring. U can circumvent the list and edit it, but its not worth going to a company with these types of practices.

    • +4

      True, though doing so is pretty easy (Google Synology_HDD_db).

      I was going to buy a QNAP recently, but with their security issues, and use of soldered RAM, I’m not sure they are better.

      • +2

        My drives have not been on their compatibility lists for at least 6 years, across 2 different Synology Models and various upgrades. Currently on 8 x 18TB drives (WD and Synology) in each NAS, none of which are on the list. Never had any issues or had to do anything.

        • +1

          Ye, i was a real fan of synology, generally rock solid, but as i grew more into self hosting and stuff, i outgrew synology's catalogue of higher end devices, i certainly didnt wanna spend thousands on their rack mounted options for not much performance/value.

          In the end i went with a custom setup of a silverstone 20 bay rack chassis and did a truenas scale server(cause zfs and dockers). essentially it did cost thousands but at least i got much more value and expansion capabilities. I would recommend small synologies for people with fewer requirements as they have a decent interface/gui os with DSM and the simplicity.

          • @Aarent: I went the same route but also used Proxmox. TrueNAS is just used as storage and for serving files. So much better than the synology route in terms of flexibility and cost savings.

      • Difference is that it has an unlocked bootloader, so you can just install a different OS such as TrueNAS or even Xpenology (basically Linux with a DSM web ui) onto it and never have to worry about QNAP’s software issues (unless it impacts the hardware).

    • +2

      Not sure of other models. But my 1821+ have 22TB WD Red Pros and 64GB (2x32) ram. Both HDD and RAM are not on their compatible list.

      • Me, too. I bought 2x Synology 4GB ECC RAM for DS1819+ and it generates incompatibility error. But it doesn't stop you from using it and ECC is enabled without issue. I believe only the enterprise XS series would enforce part limits.

  • Nice deal. I need to replace my DS213+ and I'd love to replace it with a DS723+. Totally different to this beast but I'm a simple man.

  • +15

    Under Powered n over priced

  • +3

    What are some budget NAS recommendations for a plex/jellyfin media server?

    I’ve just setup a spare laptop with an external HDD - but i worry i’ll soon run out of space once i automate it a bit more.

    I have been keeping a lookout on fb marketplace for used ones but dont know if its worthwhile going down that route.


    • +1

      Second hand where i live all seem to be 10-15 years old for $50-300 or $800+ for 2020 on. I have been looking for a while and think i will DIY.

    • +2

      Old PC. 7th gen or higher intel will have onboard QuickSync, which will be great for transcoding.

      As your HDD collection grows, you might need to grab an HBA card with IT Mode from AliExpress or eBay for around $50-70.

    • +3

      I personally bought a HP Z440 off ozb which came with a Quadro GPU (did not have h265) and chucked in a 8TB hard drive. I'm currently running Unraid OS and using it to host my plex along with a plethera of other local services/servers (adguard, arr suite, game servers, etc).

      Not sure if this is overkill/overpriced for you but it's just what I have set up. It's also probably not the smartest way to set it up but it works for me and I enjoy having a relatively powerful workstation to try a bunch of things on.

      I also upgraded the Quadro GPU to an RTX 2060 that I got really cheap off of a mate but you can most likely get a much cheaper GPU if you want to get one that supports h265 encoding. Although I did use my Plex without h265 encoding for a long time and did not have any complaints regarding quality, although I am not someone who stresses over the finer details of my video/audio quality experience anyways.

      Without the new GPU, this cost me about $400-500 for a server that can run Plex and many other things without issues.

      Hope this helps?

  • just paid $1149 for DS1522+ 8 days ago OMG!!!

    Why these things are expensive? due to security?

    • +7

      Ease of use. You basically pay for the convenience.

    • +5

      You basically see them as a box you can plug in few hdds and watch plex on. For that may be its expensive. But they have much more sophisticated service stack and capabilities

      • -1

        Can’t you just get USB hub for $30 and add hard drives?

        • +1

          You need something to process the files, 4k especially requires a bit of hardware.

    • +8

      I’ve used both QNAP and Synology NAS devices.

      Synology software is definitely easier to use, and some features seem to be geared more toward business users.

      If you want a box that sits in the corner with minimum fuss, and just works, Synology fits that bill.

    • +4

      Synology products in general attract a premium because the software is easy to use relative to the possible complexity of scalable storage solutions like these, but this thing in particular is oriented more for home office/small businesses users rather than general consumers. In that sense this is actually fairly cheap: Servers can cost hundreds of thousands of dollars in some cases, and the embedded processor in this one is old but has some of that same enterprise DNA; it's an AMD V1500B if I recall, and supports ECC RAM, which is usually used in applications for mission-critical data (in conjunction with offsite backups, etc). So rather than your anime library, the idea with this thing is you would use this unit to host a database requiring moderately high availability, or to provide high-speed storage for editing 4K video, or something which ultimately relates back to your job/income. tl;dr - if it wouldn't be a tax-deduction, you probably don't need it.

    • They're the Apple of the NAS world. Extremely overpriced because you're paying for the software just as much as the hardware, and of course can't run the software on your own hardware.

      Upto you if you see the value in it.

    • +2

      You pay for the synology tax. They load it with crap that you don't need or has opensource alternatives that are much better.

      Storage -> Truenas (or paid Unraid)
      Synology Photos/moments -> Immich
      Synology Mail -> don't bother running a mail server unless you want headaches
      Synology Office products -> Nextcloud
      Container Manager -> its just docker
      Surveilence Station -> Blueiris
      Audio/Video Station -> Plex etc.. there's a heap of stuff
      VM Manager -> Proxmox + Truenas or Unraid or Proxmox + unraid
      VPN Server -> Openvpn server

  • +3

    I’m still waiting for 1824+ or 1825+. Based on the cycle, the 1821+ is due for a refresh.

    • This. The current product range from Synology is showing its age and needs a refresh. There are not many areas left in technology where a 3-to-4 year-old device is the current model. Even enterprise storage moves much quicker. Hope to see new *24+ or *25+ models soon.

      • +1

        If they don't start releasing 2.5Gbe as standard across the range this year then they're a lost cause.
        It's standard to the bulk of motherboards now.
        How it's not standard on a device so specifically geared to benefit from it is madness to me.

        It's like buying a race car that is limited to 60kph.

    • +1

      Is there a website out there that lists all their products like the Apple buying guide? I've tried to find one before but failed to find one.

  • Ouch NAS are expensive and above my needs. On another note, would someone recommend a good DAS enclosure? 8 bay but open to consider 6 or even 4 bay? Been looking at qnap, terramasters, orico, etc can't decide.

    Just looking to use them as JBOD. Don't need anything else.

    • +1

      Think I just get a $800 techfast/nebula 4060 build and upgrade the case to JONSBO N4 NAS.

    • It's more integrated, but an Antec P101 8 bay case with a second-hand HBA would be about $200 delivered.

  • I've been waiting for an 8 bay for a while but if this can't transcode & I have an NVIDIA shield, can the shield transcode and send to external devices logged into my Plex?

    • +1

      As long as you don’t have the tube-shaped version, you can use a Shield as a Plex server with content on your NAS.

      In my experience, Shield doesn’t make a reliable Plex server however. I would pair a Synology NAS with a separate mini PC.

    • +2

      Transcoding is inferior anyway, just mount your files as network shares and play via Kodi … Kodi will play 4K lossless HDR10 OR Dolby Vision without major overhead on my DS1821+

  • +1

    Take some old pc parts and throw in unraid you are all set.

    • Booom! This is the way!

  • +2

    I’d be going for the UGreen NAS devices now. Far better value for money. Synology still using 1GB/s network ports.

    • How is software experience with ugreen?

      • +2

        Not good since it needs time to mature, but it’s irrelevant since you can install a much better OS like TrueNAS, UnRAID or OpenMediaVault.

      • Excellent, since you can install unraid.

    • Yes I'm keen to try them out when they become more widely available, they're looking great hw-wise

    • +1

      It's just that 1) UGreen DXP8800 Plus is US$899 pre-order via Indiegogo which is dangerously close to DS1821+ in this deal, and 2) I'm adding a NIC for 10GbE anyway. Given DSM is of its own league (even compared to QTS/QuTS Hero) there's really no reason not to catch this.

      Finally give me a reason to replace my DS1812+ (!!)

      • Which 10GB card can you put in this? I definitely need 10GBit for the network.

        • +1

          Mine is a Dell variant of Intel X540-T2 with a fan. Most Intel cards would work, so does Mellanox. Some Emulux would do, too. Those are quite cheap used.

          Synology official cards are mostly based on Aquantia. If you're buying new, look for the ones with Aquantia chips.

          • @xmagic: Thanks. I was wondering if the Intel cards will be limited by the 4x PCIe lanes, as I think they are X8 cards.

            • @Scrobo: Technically speaking you can run 10gbe at full speed on PCIe 3.0 x2.

              x8 cards generally because they’re old and running on PCIe 2.0. Still 4x lanes would be sufficient if you only use one of the two ports.

  • I have a 220+ that's been pushed hard and out of capacity. I've been waiting for a deal on the DS423+ but the extra bays on these models is very appealing. Shame there's no transcoding.

  • 1Gbit networking and no USB 3.2 Gen2 support?

    Are there any decently priced NAS units that have good transfer speeds? Even 10Gbe is getting a bit slow these days.

    • If you go spinning rust without SSD cache the whole system will not saturate a 10Gb connection. Just check the product datasheet. There's enough bandwidth in the PCIe slot for a dual-port 25GbE NIC to saturate its SSD slots (either for cache or storage), too. Otherwise the system performance will be the bottleneck.

      If you really need extra performance, there are models from QNAP or others with Thunderbolt connection (for CFE ingestion, for example) or other high-speed connectivity. Will be much more expensive than this one, too.

    Seem they have raised the price of the DS1522+ to $1299 and the coupon no longer works with that model.

    • +1

      Thanks, updated the post.

      • +1

        Sadly they have now also killed the coupon for the DS1621+ as well.

        • Spewing, hopefully some people after it was able to get it. Thanks, I've updated the post.

          • @shiprekt: Yeah. Seems they had put the price up for the DS1522+ just so they could discount it back down to the $1148 price for the EOFY sale. lol

            • @fsfwerefdgfgh: Probably realised how cheap it was with the discount and coupon stacking haha. But still a shame they've apparently caught on to that.

      • Haha they have now added the DS1522+ back to work with the 15% code for $975.80

        • Unbelievable ahah. They upped the DS1821+ price it seems.

  • Okay, so do I get this and throw a 10GBe card in there, or grab a Antec P101 case, and throw 8 drives in there and an inexpensive low power PC in there and a software RAID? Hmmm….

    • +1

      Up to you, comes down to what you prefer. Do you prefer to build something and setup how you want it with flexibility or want something that can just be left one 24/7 and hum away with super decent and low power consumption that just works - pretty much set and forget.

      Each person will have their own pros, cons and use cases - just got to review your own needs and weigh up your options.

    • There's no comparison as they solve different problems. You pay extra for the software bundle, sleek package and support, which you don't usually get from DIY solutions. But of course you don't get the flexibility, feature set, etc. vice versa.

      Besides Synology DSM is not actually hardware RAID - whether it's common RAIDs or SHR, they're all based on a combination of mdadm, lvm, and optionally btrfs, with their own way to manage those in a user-friendly package.

    • Build your own.

      Use unraid or truenas, whatever floats your boat.

    • Depends if you want to buy into the Synology ecosystem. I use both TrueNAS and Syno depending on requirements

  • For those out there who are using the DS1821+, did you guys upgrade your RAM? If so, which compatible one did you upgrade to, and please provide the link.

    • For "official" compatibility:

      16GB - D4ECSO-2666-16G DDR4 ECC SODIMM
      8GB - D4ES01-4G DDR4 ECC SODIMM
      4GB - D4ES01-8G DDR4 ECC SODIMM

      Check out Synology compatibility list: DS1821+ RAM Compatibility

      Reddit list including Synology and other branded RAM modules that may be an option: Reddit post

      Edit: Just be sure to double check before you buy as that reddit post is a few years old and hopefully Synology hasn't done any silly buggers since.

      I used this - https://www.amazon.com.au/gp/product/B09G4MK264/ - been running it for past two years with no problem

      • Awesome, thank you for the recommendation

    If you have an old pc just build your own. If you don't then buy one off marketplace for half the price with better specs.

  • Looks like the code has been expired ahead of time

  • Do any know if this is coming back? I missed it waiting for payday
