Synology DS923+ NAS Review

The Synology DS923+ NAS Review – AMD vs Intel?

Regardless of whether you are new to NAS or have been well-grounded in the world of premium turn-key private server ownership, there is a pretty high chance you heard about Synology! In the world of NAS, they are pretty much the top brand and with good reason. Their DSM platform has continued to evolve into a complete ecosystem of tools, services and gives a number of SaaS and PaaS alternatives in the market a run for their money, despite their hardware occasionally playing it a tad safe. Every 2-3 years we see their portfolio of solutions have updates and refreshes across the board, which is exactly what brings us to the focus of today’s review. The Synology DS923+ NAS has some particular bit shoes to fill in the form of it’s predecessor, the DS920+ – arguably one of the brand’s most popular NAS solutions in their over two decades of business! The Synology DS923+ Diskstation NAS is a device that event at its first revealed at official events in Oct’22 certainly split opinion, to put it lightly. Arriving with an AMD CPU, despite it being in a historically Intel-powerful product family (for over a decade in fact), the changes do not stop there. The Synology DS923+ NAS might just be a gamble by the company to restructure its portfolio and consolidate its already largely business-leaning position, but will buyers go along with it? Is Synology planning ahead for a change in the mindset of NAS buyers that those same buyers are not quite on board with? Ultimately, does the DS923+ deserve to be the successor to the popular and award-winning DS920+, and does it deserve your data? Let’s crack on with the review and find out!

Note – If you are interested in how the Synology DS923+ and DS920+ NAS compare in terms of hardware, software and scalability, you can find out more by visiting the article HERE on NASCompares, or watch my comparison of the DS920+ vs DS923+ HERE on YouTube.

Synology DS923+ NAS Review – Quick Conclusion

Synology has clearly made something of a gamble in the release of the Synology DS923+ NAS. There is no avoiding that making the switch from the Intel Celeron that has historically been the build choice of this product family and opting for the AMD Emb.Ryzen has ruffled some feathers! On the face of it, the R1600 here has a heck of alot of going for it over the previous generation! Higher clock speed, greater PCIe Gen 3 Support throughout, that 4-32GB of DDR4 memory in such a compact system and just generally giving you a lot more horsepower to play with, as well as better bandwidth potential inside and out! But at what cost? The 1GbE standard connectivity in the base model leaves alot to be desired, the proprietary 10Gb upgrade (though incredibly handy) limits the upgradability a tad and the lack of an integrated graphics processor is likely going to result in many long-term Synology advocates to skip this generation. Synology Diskstation Manager (DSM 7.1 at the time of writing) still continues to impress and although the brand still continues to heavily push their 1st party priorities, they have left a little more wriggle room in DSM 7.1 than DSM 7 before it in terms of media compatibility. In terms of design, I cannot fault Synology on this as the DS923+ chassis still arrives as one of the best-looking and still exceptionally well-structured devices at this physical scale and storage level. As always, a Synology NAS is more about the software than the hardware (and the DS923+ delivers in spades on the software side!) and with DSM 7.2 around the corner improving things. Just always keep in mind that the Synology DS923+ NAS is a system that arrives with the slight emphasis on having to do many things ‘their way’. If you are less technically versed, then you will definitely appreciate this level of user-friendly design and assistance, but more technically minded admins’ main strain a pinch! In short, the DS923+ IS a good NAS drive, but its focus has certainly ebbed more towards the business user this generation than the home.

Synology DS923+ NAS Review – Packaging

I won’t spend too long talking about the external packaging of the Synology DS923+ NAS, as it is remarkably similar to that of other Diskstation devices at this scale. The presentation of the retail box does have more attention to detail than you might expect though (given this is a 99% online purchased device and therefore any kind of glossy/detailed livery is almost a vanity addition!), as alongside the expected Synology logo and sticker for the model ID, the box is printed with tonnes of devices specific details. Synology has always been very, VERY aware of the power of branding with their solutions, as its little details like these (as well as embossed handles and favouring solution/every-man related terminology over cold specifications on the packaging) go a long way to set them apart from the sea of brown-box-rinse-repeat found in most online IT solutions you buy online and not at retail.

Despite the fact the DS923+ NAS is shipped unpopulated from Synology, we still need to grade/review them on the protection this unit is afforded in transit. As solid as a lot of IT kit looks, you cannot ignore the effects of shock or motion damage on them in long-distance travel from their point of manufacture (Taiwan in this case), so I will always give a brand extra points if they have gone the extra mile to spend a little more on protecting their system. In the case of the Synology DS923+ NAS, it’s mostly ok. I wish they used more hard foam/surrounding as you find in their 6-Bays and higher solutions (DS1621+, DS1821+, etc), as the DS923+ NAS arrives in a mostly cardboard structure that I think will be fine for the most part, but wouldn’t stand up to physical pressure tremendously well. Everything is separated very well and the structure/framework is there, it is just mostly cardboard! But I am being a bit petty here… let’s move on!

The DS923+ arrives with the accessories you would expect. The NAS unit itself, an external 100W PSU, Screws for 2.5″ media (3.5″ media installation is toolless), RJ45 Cat 5e ethernet cable, keys for the storage bays, first-time setup document and information on your warranty. All fairly standard stuff, though I am always surprised by the fact that Synology never include heatsinks for the M.2 NVMe SSD bays, given the high priority of the brand towards caching on these storage bays – something that can get those M.2 SSDs pretty hot.

The external PSU is Synology branded, always a nice touch, and although there is a contingent of users that prefer an internal PSU (less fuss, tidier) I will always prefer an external power supplier, as it is hugely easier to replace, reduces the size of the NAS chassis itself and keeps those internal temps a little lower too. Luckily this NAS is such a low-impact model in terms of power use that a modest external power brick is completely possible.

The retail kit for the Synology DS923+ NAS is all fairly standard stuff in contents, but still a very branded package and completely what we would have expected from this very brand-aware company! Let’s discuss the design of the DS923+.

Synology DS923+ NAS Review – Design

The chassis design of the DS923+ NAS is largely the same as the DS920+ and DS918+ that came before it. This is a particularly well-designed device, both in terms of aesthetic design AND it’s efficient system operation 24×7, with tonnes of ventilation throughout and very structured component distribution. Also, the chassis is a largely plastic external casing in matt black, that contains a much smaller structure on aluminium internally. The result is a NAS that is pretty low noise when in operation (unless you use HDDs larger than around 10TB and/or enterprise-grade 7200RPM disks), something that alot of users who plan on taking advantage of the potential increased external bandwidth that DS923+ for photo/video editing will hugely appreciate. That said, one consistent vibe you get in the design of the DS923+ is that direct/physical interaction with the device is kept to a minimum, preferring almost entirely network/internet-based interactivity. Not a huge surprise for a ‘NAS’ of course, but there are a handful of physical attributes that are intentionally absent here. The front of the chassis lacks any kind of LCD display, instead favouring LED indicators. The bulk of the front panel is occupied by the main storage bays and these have alining of ventilation all around them to act as passive airflow.

Passive airflow is definitely a big focus on the design of this chassis, with almost every side of the case featuring ventilation of one sort of around, with the Synology logo being vented. As this system will be in operation 24×7, it is heavily reliant on the rear fans to push air effectively through the system and over the assortment of internal heatsinks as effectively as possible and this chassis does that very well indeed. The Diskstation series at the 2/4 Bay level has always done a great job of melding modern design with necessary system temperature management and the DS923+ is no exception.

The LEDs on the front of the system use the usual three-colour system to denote drive activity and system status (network activity is absent, but the usual LEDs on the RJ45/Ethernet ports themselves are still present). These can have their brightness adjusted (or deactivated entirely) and although lack alot of the more information abilities of an LCD panel (IP addresses, system temp, alert description), they still serve ok as an initial indicator of system activity.

The main four storage bays of the DS923+ NAS are SATA interfaces and can be fully or partially populated with 2.5″ or 3.5″ media. The HDD/SSD compatibility of the DS923+ is still thinner than that of the DS920+, but Synology softened its stance a pinch on this subject after DSM 7.1 and the negative feedback on stricter HDD compatibility (i.e Synology media only). Although the full compatibility list is not as broad as that of the DS920+, we expect more drives to be added after launch (much as we saw with the DS1522+ and RS422+), though drives above 18TB are still absent (at the time of writing) despite 20TB and 22TB hard drives being tested on the DS923+ and working immediately. These four bays also allow you to use a large range of RAID configurations (redundant array of independent disks – a system of combining multiple drives to benefit storage scale, performance and/or data redundancy/safety-net). The usual configurations are here, RAID 0, RAID 1, RAID 5 and RAID 6, but the system also supports Synology’s Hybrid RAID (SHR) which allows you to mix different HDD/SSD capacities. It’s pretty unlikely that you will mix drive media on day 1, but if you partially populate or want to upgrade your drives gradually a few years down the line, SHR is SIGNIFICANTLY easier to expand and absorb newer/larger drives into an existing RAID. That said, the performance of SHR is a pinch lower than RAID 5, so for those hoping to take advantage of the 10GbE connectivity might do well to think about their Day 1 RAID and it’s impact down the line.

The trays themselves are plastic click-n-load tracks that feature a locking mechanism. It’s worth highlighting that this lock is by no means ‘industrial’ and removing a drive is going to be easy for particularly nefarious individuals, but this lock is more to prevent accidental removal than it is as a meaningful security barrier. The trays have screw holes for 2.5″ media to be installed with screws, but 3.5″ media is installed in seconds with the use of side clips that hold the drive in place via it’s own fixtures. The plastic tray is pretty sturdy and heat/cracking is not going to be any concern here. Also, the plastic trays will lower the ambient noise level when in operation more than metal trays would do, but (sorry to be repetitious) if you use bigger than 10TB HDDs, it is simply not possible to reduce the clicks, hums and whurs of these more industrial drives.

The front of the DS923+ NAS also features a USB port that can be used for connecting an external drive for backups in either direction (i. backup the drive contents to the NAS, or present files and folders to the NAS to the drive). Now, the DS923+ does not feature a front-mounted copy button (bit annoying) but DSM does include a USB copy tool that allows drives to automatically trigger a pre-set USB-to-NAS or NAS-to-USB operation when a drive is connected, which is pretty detailed in its setup (pre-set directories, age of files, exclusions, schedules, versioning, etc).

M.2 NVMe Storage Pools on the DS923+ NAS

UPDATE 16/11/22 – We just received word that the M.2 NVMe SSD Bays on the DS923+ and several other Synology NAS systems are going to be usable for both Storage Pools and SSD caching. Details are emerging on this, but much more information on this can be found here – https://nascompares.com/2022/11/16/synology-nas-and-m-2-nvme-ssd-storage-pools-finally

UPDATE 23/11 – M.2 NVMe SSD Bays as Storage Pools Confirmed (images of use and storage options) are detailed here in a newer post – https://nascompares.com/2022/11/16/synology-nas-and-m-2-nvme-ssd-storage-pools-finally

(Back to the review)

M.2 NVMe SSD Support on the Synology DS923+ NAS

Looking at the base of the DS923+ NAS shows us those two m.2 NVMe 2280 SSD slots, each with a ventilated top panel. These two slots support a PCIe Gen 3 SSD in each bay (which can be partially/fully populated) in order to take advantage of SSD caching in the Synology storage system. Caching can consist of Read Caching (when more frequently accessed data is copied to the faster SSD to allow faster retrieval later, though the benefits are only really felt/observed in smaller data) and Write Caching (When data being uploaded/sent to the NAS is initially written to the SSDs and then moved to the internal larger/slower HDD RAID array.

As beneficial as this sounds, it is still a pain that (at the time of writing) these NVMe SSD bays cannot be used for raw storage pools, as there are a number of popular 1st/3rd party applications that would hugely benefit. Still, as more and more Synology NAS systems arrive with M.2 slots AND these are all predominantly PCIe Gen 3×4 in the 2021/2022/2023 generation, I would not be surprised if we see Synology decide to change their position on this in a future DSM update. For now though, these fast SSD bays are restricted to cache use only (though a workaround will no doubt arrive on a GitHub page near you soon enough!).

I have always been a big fan of the Synology Diskstation chassis for it’s minimalistic, yet attractive and efficient design. The absence of a USB copy button still irks me a little and the largely plastic design is not going to be to everyone’s taste, but you cannot fault the amount of R&D that has gone into the construction here. Let’s discuss the ports and connectivity of the DS923+ NAS.

Synology DS923+ NAS Review – Ports and Connections

The ports and connections that the DS923+ NAS arrives with are something of a mixed bag and compared with the 2020 released DS920+ only real include on different (but it IS a BIG difference). The system has two active cooling fans (2x 92mm) that will automatically adjust their RPM as the system’s ambient temperature requires. You can adjust these manually if you are especially noise-sensitive, but I would really recommend it (a low system temp = better system efficiency). The fans are not removable (built into the back panel of the system), so cleaning and maintenance are a little fiddly, but thanks to the large amount of ventilation afforded to the system, this is not really an issue long-term.

Let’s get the elephant in the room out of the way early doors! Those ethernet ports. The default model of the DS923+ NAS arrives with two-gigabit ethernet ports (the same as the DS920+, DS918+ and DS916+ before it), despite almost other commercial NAS brand producing solutions at this consumer-tier/scale arriving with at least 2.5GbE. Now, the adoption of greater than gigabit connectivity in client hardware (laptops, PCs, routers, switches, docking stations, etc) is by no means as ubiquitous as 1GbE (which has been around for decades at this point), BUT it is growing. ISPs are providing fiber internet connections globally that exceed gigabit speeds, along with 2.5GbE and WiFi 6 routers. We are seeing more prosumer switches, routers and PCs with default 2.5Gb network ports (at the same/similar cost as 1GbE), $20 USB-to-2.5G adapters and even the affordability of 10GbE on some client devices has allowed users to gradually scale up their hardware environment. The fact the DS923+ arrives at the tail end of 2023 and does not feature greater than 1GbE ports by default is quite damning. Even if you have no plans for 2.5G right now in your setup and think it something of a fad (favouring 10GbE), in terms of future-proofing and the general standard or networking hardware right now, gigabit ethernet is a surprising weakness here.

HOWEVER, we do need to acknowledge the bit change that the DS923+ brings over it’s 2.5yr older predecessor – the ability to upgrade your network connectivity to 10GbE. The DS923+ is now the 3rd Synology NAS to arrive (after the DS1522+ and RS422+) with support of the Synology E10G22-T1-mini, a proprietary network upgrade module that is one of the easiest and quickest upgrades that I have ever seen to 10G to install! This module fits neatly (by design of course) into the PCIe Gen 3 x2 network upgrade slot, though powering down the device is necessary during installation. At first, I was a little sceptical about Synology providing a 10GbE upgrade to the DS923+ via a custom-made and largely proprietary designed upgrade module (thereby limiting you to ONLY the Synology PCIe upgrade, but not any other traditional PCIe Card 10G upgrades), but over time I have come round a little on this one.

I like how easy this is to install (zero case deconstruction) and it is a very well-designed component (not just a rebadged card with a logo). The 10G upgrade is only available in copper (RJ45/10GBASE-T) currently, but I would not be surprised if Synology roll out an SFP/SFP+ version down the line. As much as I would like to see this port and it’s utility get expanded (2.5G/5G, Dual port?), realistically this is still a PCIe 3×2 slot (so maximum 2,000MB/s to play with and that’s without network/hardware friction) and the physical space here is pretty small.

The next question many will have about the DS923+ and this optional 10GbE upgrade is, can you even saturate a 10G (1,00MB/s+) connection with 4 bays of SATA storage? It’s a good point, as generally, domestic-class NAS HDDs will give you about 180-220MB/s max, with enterprise-class (or Pro) drives giving you 250-275MB/s. RAID configuration will add to this by increasing performance per drive by around 120-200MB/s per extra drive  (again, class dependant) and even Synology on their official pages stated sequential performance of 625/559 MB/s Seq Read/Write. So, is 10GbE on the DS923+ a bit ‘pie in the sky’ anyway? Well, no. As mentioned previously here on NASCompares (sorry to be repetitious) I have performed 10Gbe tests with 4x WD Red Pro 22TB Hard Drives in a RAID 5/0 on the DS1522+ (same CPU, but twice the memory) and managed on several occasions of ATTO Disk benchmark testing to hit 1GB (1.15GB/s) speeds (see below). I will be conducting more specific performance tests on the Synology DS923+ NAS later for YouTube (and updating this review accordingly), but this does pretty much show that the DS923+ have the wherewithal the saturate 10GbE in specific setups.

The DS923+ also have an additional USB Port on the rear and it is here that we should touch on another thing about the device that I am a little less blown away by. The USB ports here are USB 3.2 Gen 1, so 5Gb/s (500-500MB/s max bandwidth). Much like the 2.5G vs 1Gb complaints I made earlier, most other NAS brands at this hardware tier have rolled in USB 3.2 Gen 2 (10G / 1,000+ MB)  ports, as well as USB-C in some cases. With the ease with which a user can add a USB tier to their 3-2-1 backup strategy (allowing them to be a little more financially creative with a network/remote/cloud backup tier as well), the slightly old skool USB ports here are a little underwhelming. With significantly more affordable RAID-enabled USB solutions in the market and/or M.2 NVMe external USB drives arriving affordable to comfortably provide faster external storage for backups, this seems like a bit of a misstep by Synology to ignore. Also, DSM 7 and DSM 7.1 (with DSM 7.2 coming soon enough) have reduced the range of use of the USB ports of Synology NAS systems (removing many network adapters, DTV tuners, wireless dongles, office accessories such as printers, scanners and optical drives), and limiting them largely to storage, UPS’ and assigning them to VMs. I am sure Synology has done the market research and observed reduced utilization of USB on their systems to dictate this decision, but it seems to be another move by the brand to prioritize network/remote access only with their systems.

Lastly, there is the expansion port that allows you to attach the official 5-Bay DX517 expansion device. This £350-400 5x SATA Bay JBOD enclosure is connected via a screw-in eSATA connection and allows you to either expand an existing RAID to increase the drive quantity and capacity overall (though not recommended to spread RAIDs over NAS+Expansion). Alternatively, you can use the expansion as a means to create an additional separate RAID configuration (which can also be gradually populated) that is treated exactly the same as the internal storage of the DS923+. The fact this expansion is JBOD only means that the RAID is managed by the main DS923+ device (which given the expansion cost, is a little annoying), but having this expandability is very useful. You cannot use third-party eSATA JBOD enclosures (unsurprisingly) and you can not get smaller/larger expansion chassis that are compatible with the DS923+, but the support of an expansion does mean that your storage options years down the line have this official option.

Overall the ports and connectivity of the DS923+ are technically no differences in the base model than the 2.5yrs older DS920+, it is only the option to add improved network connectivity towards 10GbE (and paying £129-139 extra for that) that makes this any way improved upon as a refresh of the older device. This upgrade is certainly welcomed, but there is still the hanging question of why they could not just roll this into the DS923+ as a default port on day 1 and just increase the price £100 – as I think there is a good % of NAS users who would have preferred this (especially with 10GbE largely supporting auto-negotiation with 5G, 2.5G and 1G, therefore allowing backwards compatibility). The expandability in storage and USB support remains exactly the same too, which is a little ‘meh’. Let’s take a closer look at the internal hardware and discuss the other big changes that the DS923+ brings over its predecessor.

Synology DS923+ NAS Review – Internal Hardware

This is likely to be one of the biggest areas of contention for many users who have been waiting for the release of the DS923+, as the hardware choices that Synology has made for this system are quite a change of architecture that many expected. The internal framework of the DS923+ is an aluminium storage cage for the main SATA bays, with its own multi-port backboard. The same goes for the M.2 NVMe SSD bays, with both of these boards connecting to the controller board that has CPU and Memory storage.

As mentioned earlier, the DS923+ does not take advantage of any active cooling systems (beyond the rear fans) and is heavily reliant on heatsinks internally to dissipate the heat from key components like the CPU and disperse that heat into the air. The CPU inside the DS923+ is the AMD Embedded Ryzen R1600 processor, an x86 64bit Dual core, four-thread processor with an impressive base level clock speed of 2.6Ghz that can be scaled up to 3.1Ghz when needed. Now, the DS9xx+ series has always arrived with a Quad Core Intel Celeron (or Pentium) processor in the past and when it was revealed that the DS923+ was arriving with a dual-core embedded ryzen, many users were a little unhappy. This was largely down to two factors. The first was that the R1600 is a dual-core, not the four-core that everyone expected. Now the R1600’s four-thread architecture does allow the CPU to spread out quite alot across tasks and services (as well as virtual CPUs in VM deployment), as well as having a higher power in both base and burst mode available, which means it isn’t a bad CPU! But the bigger area of contention from some buyers is that the R1600 lacks integrated graphics. This means that for some tasks and services that are more graphical in nature, the result will be a higher typical CPU Uages % than a processor that has a more specialized graphics management component onboard.

How the Synology DS920+ Intel Celeron J4125 and DS923+ AMD Emb.Ryzen R1600 Compare:

The traditional data handling of the R1600 is very good, as seen in our DS1522+ testing earlier in 2022. As far as DSM (the Synology software) is concerned it will be able to run EVERYTHING! Additionally, the general file handling and throughput internally are going to be great too, so all good news. Then you have the advantage of the newer gen CPU in the DS923+ over the DS920+ supporting PCIe3 lanes, affording greater bandwidth to the rest of the hardware (i.e those M.2 slots being higher bandwidth and enabling that network upgrade slot), all the while with the CPU having the potential to hit 3.1Ghz of power when needed. It is genuinely a good CPU and there are lots of reasons why Synology have opted for this CPU, but it is by no means perfect and some specific user setups and their concerns do have merit.

For a start, the AMD R1600 has a higher typical usage (unsurprising for the spec and generally identified as TDP, as a maximum) compared with the avg Intel Celeron being used in other NAS systems released in 2022 (such as the Intel N5105 or J6412) and in a system that will be in operation 24×7, this is going to a question mark for those affected by erratically rising energy prices right now, The difference might only be pence on the day, but those pence add up! Then there is the dual cores. Although having the four threads IS handy and will be useful, Cores will always beat threads when it comes to capabilities. Finally, there is that lack of integrated graphics. Most users will not notice this as an issue in day-to-day use, but multimedia users and especially a large % of Plex users will notice, if they are a little more reliant on the server-side processing than on the client. For example, if your media collection contains alot of dense/complex audio media (RAW, MP4a, etc) OR alot of higher-end HEVC/H.265 Media BUT you do not have client hardware that supports these types (or allows local client conversions/transcoding), then the NAS will have to use raw horsepower to get the job done – much less efficient than embedded graphics doing the job. Again, you might not be impacted by this (your client hardware might have enough power and privileges, or you own a local HEVC-licensed device), but it IS a concern if you are running a Plex Media Server on the DS923+ and need the NAS to convert files on the fly. Earlier in 2022, I compared the DS920+ (with a Celeron) vs the DS1522+ (with this same AMD R1600) in a detailed YouTube video testing 4K Media in Plex. Here are the results:

Next, we can move on to the other big internal change that the DS923+ NAS has arrived with over the DS920+ before it, the Memory. The DS923+ arrives with 4GB of DDR4 Memory like it’s predecessor – but after that, it is all change! This memory is ECC (Error Correcting Code) memory that is more often found in enterprise NAS setups, due to its higher pricetag, but also its huge benefits towards avoiding bitrot and silent data inconsistency that are not going to be spotted till years down the line when accessing old data. As data passes through the memory, the memory has an additional onboard module that is designed to be constantly making a blueprint/snapshot/parity bit of the data at the start. This is then used to check the data on the exit path and if there are any inconsistencies, the data is remapped/repaired to its original form.

ECC Memory has appeared on lots of Synology NAS’ over the years (with pretty much ALL devices higher than ‘mid-high business having it as standard now), so it is great to see it here on this 4-bay diskstation model. In other good news, whereas the DS920+ had 4GB of memory that was soldered to the main controller board and could be upgraded to 8GB with 1 free slot, the Synology DS923+ has two slots available (one prepopulated with the initial module) and can be upgraded to a massive 32GB. This again is thanks to that R1600 CPU being used. Although Synology still maintains quite a tight compatibility/whitelist on supported memory modules (stating that you can/should ONLY use their own first-party modules), I cannot fault the choice of memory and its upgradability here!

In summary, in terms of the internal hardware, I am mostly happy. The lack of an integrated graphics processor (especially when the same AMD Embedded Ryzen R1000 CPU family has a graphics-equipped model, which was passed over here for the R1600) is a real pain for alot of users, but by no means does it mean this NAS is a write-off! That CPU has alot of capabilities, has opened up the hardware on the system to greater bandwidths, is capable of great internal+external performance and outside of conversion-based activities in multimedia, and still plays 4K and 1080p media very well. There are a few other details regarding AMD Emb.Ryzen vs Intel Celeron that you can learn more bout by reading this article HERE, but let’s move on to the Software side of the Synology DS923+ NAS and DSM 7.

Synology DS923+ NAS Review – Software and Services

At Launch, the DS923+ NAS arrives with the latest version of Synology software, DSM 7.1. However, this does not stop evolving as soon as you get your Synology NAS. DSM has been in continues to be the dominant force in the world of NAS software, providing a massive arrangement of services, applications (first and third-party supported) and a huge number of client applications for desktop, mobile, Windows, macOS and Linux (as well as a bunch of other more home-based tools). These allow management and access to the data on the DS923+ in very tailored ways, as well as the web browser-based access that has the appearance, intuitive design and responsiveness of a local operating system. The DSM interface can be accessed by hundreds of users at the same time (with each user having tailored access, rights and privileges). DSM is available with ALL Synology NAS and the depth and abilities of DSM on any NAS are dependent on the hardware architecture of the NAS itself. In the case of the Synology DS923+, it supports EVERYTHING that is offered by Synology’s platform. DSM is currently in version 7.1, but it looks like we will be seeing beta/full release of DSM 7.2 at the end of 2022 or the start of 2023, which will be adding WORM (write Once Read Many) support, Volume scale encryption and numerous improvements to individual applications. If you want to learn about the DSM 7 and the software and services that are included with the DS923+ NAS, watch my FULL review below (alternatively, you can read the DSM 7 Full Review HERE):

As mentioned, the DS923+ supports pretty much the entirety of the DSM 7.1 applications and services (DSM 7 and DSM 6.2 are still in circulation and still receive regular service and security updates, though the DS923+ will arrive with DSM 7.1 by default and cannot be rolled back). If you are an existing user of SaaS and PaaS (Software as a service and Platform as a service) from the likes of Google Workspace and Office 365, knowing that you can synchronize these systems or choose to export away from them onto the Synology services is going to be very appealing. Then there is the increasing development of their 1st party cloud platform, Synology C2, which is slowly integrating into all the applications that are available on your bare metal NAS (allowing you to add a cloud layer of backup, synchronization and access to your data storage setup). This is a subscription platform, which can only be used with your Synology NAS system (as well as connected with some 3rd party SaaS services, but for those that are moving away from Google/Microsoft/AWS for security reasons, but still want a Cloud+Metal storage network in place, C2 covers pretty much everything. Indeed, although below I have highlighted a number of the key/best applications that are included in your DS923+ Service with DSM, most of them can be immediately integrated with Synology C2  (with even more being added in 2023 with DSM 7.2). Key business and consumer applications that are included with your NAS are:

Synology Office – Create documents, spreadsheets, and slides in a multi-user environment. Real-time synchronization and saving make collaboration a breeze.

Synology Chat – Aimed at businesses, Synology Chat is an IM service that transforms the way users collaborate and communicate.

Synology Drive – Host your own private cloud behind the safety of your NAS with 100% data ownership and no subscription fees. Drive has become one of the premier applications of DSM and allows uses to create intelligent shared team folders that support versioning, file streaming+pinning, encryption, Windows AD support (soon) and native file system support with Windows and macOS.

Synology Photos – Manage your photos and videos with deep-learning algorithms that automatically group photos with similar faces, subjects, and places. Designed after the merger of Synology Photo Station and Moments, it also includes tailored folder, sharing and categorization features to help photographers manage their photos and share them with clients for feedback or business development.

Synology Calendar – Stay on track, share calendars, and schedule meetings, while ensuring sensitive information remains safely stored on company premises.

Synology Active Backup for Business (ABB) – Consolidate backup tasks for virtualized environments, physical servers, and personal computers, and rapidly restore files, entire machines, or VMs – license-free. This software also arrives as a specialised Microsoft Office 365 and Google Workspace platform to sync with those platforms and allow a bare metal tier to your cloud office services

Synology Hyper Backup – Backup your NAS safely and efficiently to multiple destinations with deduplication, integrity checks, compression, and versioning.

Synology Surveillance Station – Safeguard your business, home, and other valuable assets with reliable video surveillance tools. With improved AI services being accessible thanks to Synology BC500 and TC500 Cameras arriving in 2023. Additionally, you can connect this platform with Synology’s cloud platform to use ‘C2 Surveillance’ and bolster the odds of recordings being maintained in the event of accidental/malicious damage to your surveillance system.

Synology Virtual Machine Manager (VMM) – An intuitive hypervisor that supports Windows, Linux, and Virtual DSM virtual machines. Its powerful disaster recovery tools help users achieve maximum service uptime.

Synology High Availability – Synology High Availability (SHA) combines two Synology NAS servers into one active-passive high-availability cluster, alleviating service disruptions while mirroring data.

Synology Central Management System (CMS) – Synology CMS allows you to manage multiple Synology NAS servers quickly and conveniently from a single location.

Synology Video Station – Manage all your movies, TV shows, and home videos. Stream them to multiple devices or share them with friends and family.

Synology Audio Station – Manage your music collection, create personal playlists, stream them to your own devices, or share with family or friends.

Synology File Station – Manage your Synology NAS files remotely through web browsers or mobile devices. This tool allows complete file management and contains all the features and services of your own native file management platform (archiving, extracting, Copy, Cut, Paste, Sharing, native file format opening, integration with the rest of the Synology applications, property/metadata access, etc)

You cannot really fault the software and services that are included with the Synology DS923+ NAS, as you are going to get the very best experience available on the platform, thanks to the hardware and architecture of this NAS. DSM 7 is an ever-evolving platform, so if you are reading this now at the time of publishing or years later, there is always going to be something in DSM for everyone. That said, Synology in recent years has been increasing its priorities towards first-party software and services. This does make sense, as they want to promote their systems and software as a complete ecosystem for your home or business data storage needs (going on in the last few years to release even more Synology alternatives to popular software AND releasing non-NAS hardware accessories such as Routers, Network Adapters, HDDs, SSDs and now IP Cameras). This can occasionally lead to the compatibility lists of hardware or software that you wish to use in conjunction with the DS923+ NAS being a little smaller/restricted than you might like. A specific 3rd party software/service or physical accessory (HDD, Memory module, Network Upgrade) might not appear on the Synology compatibility pages, but that does not mean it will not function with the DS923+ NAS. It is more a case of Synology choosing not to test/evaluate a particular setup (in their defence, there are ALOT) and therefore until stated otherwise is therefore listed as incompatible and is therefore being used without their full, guaranteed support long term. In short, you can DEFINITELY feel that DSM 7/7.1 is a fantastic NAS platform, but it comes with a certain degree of rigidity by Synology on the DS923+ NAS. A little more relaxed than entries in the Enterprise XS or SA systems, but it is definitely still there.

NOTE – Video Review is ‘In Progress’ and will include the 10GbE and DSM 7.1 Testing, which will also be added to this review shortly afterwards. Apologies for the delay.

Synology DS923+ NAS Review – Conclusion & Verdict

Synology has clearly made something of a gamble in the release of the Synology DS923+ NAS. There is no avoiding that making the switch from the Intel Celeron that has historically been the build choice of this product family and opting for the AMD Emb.Ryzen has ruffled some feathers! On the face of it, the R1600 here has a heck of alot of going for it over the previous generation! Higher clock speed, greater PCIe Gen 3 Support throughout, that 4-32GB of DDR4 memory in such a compact system and just generally giving you a lot more horsepower to play with, as well as better bandwidth potential inside and out! But at what cost? The 1GbE standard connectivity in the base model leaves alot to be desired, the proprietary 10Gb upgrade (though incredibly handy) limits the upgradability a tad and the lack of an integrated graphics processor is likely going to result in many long-term Synology advocates to skip this generation. Synology Diskstation Manager (DSM 7.1 at the time of writing) still continues to impress and although the brand still continues to heavily push their 1st party priorities, they have left a little more wriggle room in DSM 7.1 than DSM 7 before it in terms of media compatibility. In terms of design, I cannot fault Synology on this as the DS923+ chassis still arrives as one of the best-looking and still exceptionally well-structured devices at this physical scale and storage level. As always, a Synology NAS is more about the software than the hardware (and the DS923+ delivers in spades on the software side!) and with DSM 7.2 around the corner improving things. Just always keep in mind that the Synology DS923+ NAS is a system that arrives with the slight emphasis on having to do many things ‘their way’. If you are less technically versed, then you will definitely appreciate this level of user-friendly design and assistance, but more technically minded admins’ main strain a pinch! In short, the DS923+ IS a good NAS drive, but its focus has certainly ebbed more towards the business user this generation than the home.

Synology DS923+ PROS Synology DS923+ CONS
  • DSM 7/7.1 (and DSM7.2 Around the corner) still continues to be an absolute tour-de-force of NAS Software
  • This latest generation expandable 4-Bay arriving with a 10G Upgrade Option is fantastic
  • ECC Memory Support and scalability to 32GB is completely unparallel at this price point
  • The design of the DS923+ NAS still continues to be market-leading
  • The New CPU architecture allows great PCIe3 bandwidth to be afforded to the rest of the hardware, inside and out
  • Low Noise, Low Physical Impact and Intelligent Automatic Power Use Adjustment Settings
  • Increased Support for macOS in Synology Drive and Active Backup Suite (DSM 7.2)
  • Synology C2 Cloud Services, 1st Party Backup/Sync Tools and Collaboration Suite App = Complete 1st Party Eco-system that can rival Office365 and Google Workspace
  • PCIe Gen 3 M.2 NVMe SSD Support as Storage Pools!!! FINALLY!
  • Tremendously User-Friendly!!!
  • The AMD Emb.Ryzen instead of a Intel Celeron (with Integrated Graphics) will be a dealbreaker for alot of users
  • The default 1GbE ports that the system arrives with are tremendously dated
  • The USB ports on the system are older gen USB 3.2 Gen 1 (5Gb/s) and their support/usability have been quite pared back in recent DSM releases
  • The continued moves by Synology to prioritize 1st party hardware and software services may put some users off
  • Plex Support on the Synology DS923+ is still great for native playback, client-side handling and client devices with relevant multimedia licenses in place, but if server-side media conversions are needed – this system will struggle in comparison with the DS920+ before it
