Synology DS925+ NAS Officially Launches in Eastern Markets – Full Specs and Features Confirmed

Following early retailer listings and semi-official leaks earlier this year, the Synology DS925+ NAS has now been formally launched in Eastern markets, including Taiwan, Japan, and China. With full documentation and product pages now publicly available, we finally have confirmation of the system’s complete hardware and software capabilities, as well as early indications of pricing and the compatibility of Hard Drives and SSDs (something of a hot button topic of late). As expected, this system builds on the DS923+’s foundation but introduces key changes that shift its performance profile and position within the Synology portfolio once again!

At the heart of the DS925+ is the AMD Ryzen V1500B, a quad-core, eight-thread processor previously used in larger business-class NAS models like the DS1621+, DS1821+, and DS2422+. Its integration into a 4-bay unit marks the first time this CPU has appeared in Synology’s enthusiast/prosumer tier, bringing greater virtualization, multi-user performance, and multitasking efficiency to this class. With a base frequency of 2.2 GHz and TDP of 16W, the V1500B is a lower-power but more scalable chip compared to the dual-core R1600 in the DS923+, which has a higher clock but fewer threads. This change benefits users focused on Docker, VMs, or simultaneous file operations.

Confirmed in the datasheet is the DS925+’s dual 2.5GbE network ports, supporting Link Aggregation (LAG) and SMB Multichannel, allowing up to 5GbE aggregate throughput—a significant improvement over the DS923+’s 2x 1GbE configuration. Expansion also sees a shift: the DS925+ uses the new DX525 expansion unit, connected via USB-C (6Gbps), replacing the legacy eSATA-based DX517. Internally, the system includes four hot-swappable drive bays (3.5″/2.5″ SATA HDD/SSD), and two M.2 2280 NVMe Gen 3 slots for SSD caching or storage pools (when using Synology’s SNV series drives).

Memory support includes 4GB of DDR4 ECC by default, expandable up to 32GB via two SODIMM slots, and the system supports 200TB volumes (with 32GB RAM) and up to 32 internal volumes. Storage management features are as expected from DSM 7.2+, including Snapshot Replication, Hyper Backup, Active Backup for Business, and Hybrid Share. While the system does not support 10GbE upgrades (removal of mini PCIe slot), Synology appears to be emphasizing strong native network performance and reduced complexity over modular upgrades.

Physically, the chassis weighs 2.26kg, has two 92mm fans, and offers 2 x USB 3.2 Gen 1 ports, alongside one USB-C expansion port. It operates within a 0°C to 40°C range, supports high altitudes up to 5,000m, and includes all standard Synology DSM security tools: firewalls, encrypted folders, SFTP, HTTPS with custom ciphers, and Adaptive MFA. As a data platform, the DS925+ supports 500,000 hosted files in Synology Drive, up to 80 Office users, and 150 Synology Chat users. On the virtualization side, it supports VMware, Hyper-V, Citrix, OpenStack, and allows for up to 8 virtual DSMs or VM instances (license-dependent). Surveillance support includes two default camera licenses, and scalable support for up to 40 IP cameras at 1200FPS (H.265), with full integration into Surveillance Station and optional C2 cloud backup.

Synology DS925+ Pricing and Availability

Following the official launch of the Synology DS925+ NAS in Eastern markets—including Taiwan, China, and Japan—we now have more concrete pricing details. In China, the base unit without drives is priced at ¥4,999, which converts to approximately £500 before tax. Pre-configured options are also being sold, featuring combinations of Synology’s own-branded hard drives in 4TB, 8TB, 16TB, and even 64TB arrays. For example, a DS925+ with 2 x 8TB Synology drives (16TB total) is listed at ¥8,469 (~£845 pre-tax), while a fully populated 64TB configuration with 4 x 16TB drives is priced at ¥14,919 (~£1,490 pre-tax). In the UK and other Western markets, the DS925+ is expected to launch in early May, with Amazon UK listings already live very briefly last week before it was taken offline, showing the base unit at £550 including VAT. Here’s a rough estimate pricing table for the Synology DS925+ configurations, converted from Chinese Yuan (CNY) to both US Dollars (USD) and British Pounds (GBP) using the exchange rates as of April 22, 2025 (remember this does not precisely calculate tax across nations and their currencies, so these are for rough guidance only):

  • 1 Yuan= 0.1371 USD

  • 1 Yuan = 0.1025 GBP

Configuration Price Yuan Price (USD) Price (GBP)
DS925+ (Diskless) ¥4,999 $685 £512
DS925+ + 2 x 2TB HDD (4TB total) ¥6,379 $875 £654
DS925+ + 2 x 4TB HDD (8TB total) ¥6,659 $913 £683
DS925+ + 4 x 2TB HDD (8TB total) ¥7,759 $1,063 £795
DS925+ + 2 x 6TB HDD (12TB total) ¥7,479 $1,025 £766
DS925+ + 2 x 8TB HDD (16TB total) ¥8,469 $1,161 £868
DS925+ + 4 x 4TB HDD (16TB total) ¥8,319 $1,140 £853
DS925+ + 2 x 12TB HDD (24TB total) ¥9,679 $1,327 £992
DS925+ + 4 x 6TB HDD (24TB total) ¥9,959 $1,365 £1,020
DS925+ + 2 x 16TB HDD (32TB total) ¥9,959 $1,365 £1,020
DS925+ + 4 x 8TB HDD (32TB total) ¥11,939 $1,635 £1,224
DS925+ + 4 x 12TB HDD (48TB total) ¥14,359 $1,968 £1,472
DS925+ + 4 x 16TB HDD (64TB total) ¥14,919 $2,046 £1,528

Note: Prices are approximate and based on exchange rates as of April 22, 2025. Actual prices may vary due to fluctuations in exchange rates and regional pricing policies with regard to inclusive tax at checkout.

The accompanying DX525 5-bay USB-C expansion chassis—which replaces the legacy DX517 and uses a similar metal casing—is priced at £439. These prices align with Synology’s long-standing strategy of maintaining consistent MSRP targets for its 2-, 4-, and 5-bay Prosumer-tier NAS units year-over-year, even when internal hardware evolves.

Synology DS925+ NAS HDD Compatibility in 2025

One of the biggest shifts accompanying the DS925+ release is Synology’s newly enforced drive compatibility policy on 2025 and newer NAS systems. Starting with this model, only drives listed on the official Product Compatibility List (PCL) will be supported during initial installation. At launch, this list consists exclusively of Synology-branded HDDs and SSDs, though Synology has confirmed that it plans to expand the third-party validation program moving forward. This move represents a broader shift by Synology toward an appliance-like ecosystem, citing increased reliability, faster support diagnostics, and significantly reduced system anomalies when validated media is used. According to the company, using listed drives can reduce storage-related issues by up to 40%, while severe disk anomalies on newer systems have reportedly decreased by as much as 88% under the new policy. Even though the DS925+ NAS has not been globally launched, in the regions it HAS been launched (China, Australia and Jopan, at the time of writing) it has opened up access to the DS925+ hard drive compatibility pages. Here is what you will find:

Practically speaking, this doesn’t mean you can’t install third-party drives (e.g. Seagate or WD), but using unlisted drives may limit your access to certain features—such as volume creation, deduplication, disk health analytics, automatic firmware updates, and even eligibility for Synology technical support. Fortunately, drive migrations from older Synology systems are supported, and older Plus series models (up to and including 2024) remain unaffected.

Still, new users and businesses investing in DS925+ hardware should factor these limitations into their decision, especially if they plan on using existing non-Synology drives. We are still awaiting FULL confirmation on the extent of the utility of 3rd party HDDs in realword use however. For example – can you even initialize a Synology DS925+ NAS with unverified Synology Hard Drives? There have been claims online that you cannot – but until this is fully verified, I/we will need to hold off full judgement!

Final Thoughts

The Synology DS925+ marks a meaningful update to the company’s 4-bay Plus series—bringing improvements in multi-core processing, networking, and system efficiency. The shift to a more capable 4-core, 8-thread AMD V1500B CPU, combined with 2.5GbE networking and modernized expansion via USB-C, ensures this model is better suited to the needs of virtualized, multi-user, and SMB environments. Yet, some users will see the removal of the PCIe slot for 10GbE upgrades as a notable loss, especially compared with the DS923+ which retains this feature.

That said, the DS925+ does benefit from many refinements learned across the Synology portfolio, and its arrival coincides with a broader strategy shift—one that tightens integration between hardware and software while prioritizing platform consistency. This NAS is clearly aimed at power users and businesses ready to invest in Synology’s controlled ecosystem, and for those who are fine with that trade-off, it offers a lot of value. However, prospective buyers who are still committed to third-party drives or planning future high-speed networking upgrades may want to carefully weigh their long-term priorities before making a decision.

Synology 2025 NAS Hard Drive and SSD Lock In Confirmed – Bye, Bye Seagate and WD

Par : Rob Andrews
16 avril 2025 à 12:30

Synology is closing the gap on third-party hard drive support further in 2025

UPDATE 3 – Synology has now made the DS925+ NAS NAS Product Page live in several of the Eastern regions (China, Australia, Japan – not the Taiwan page yet however). With it, we can now see the official compatibility pages. On the hard drive page there is now only Synology Drive media, and the option to select supported 3rd party HDD choices is removed. For all we know, this will return if/when 3rd party drives from WD and Seagate are verified. But at least for now, it seems the brand is serious about only recommending its own storage media in their 2025 systems at launch:

The full list of drives includes the Synology Plus series of HDDs, the Enterprise class drives and the enterprise class SATA SSDs. However, there are currently no Surveillance class drives listed (WD Purple/Seagate Skyhawk, etc):

In terms of M.2 NVMe SSD support, the brand has also removed any selection of 3rd party SSDs from Samsung, WD, Seagate, etc. I am particularly surprised about this, as their own M.2 drives are good for durability, but performance-wise are much lower than most in the market and whether it is as caching drives or as storage pools, there are definitely a lot of good options in the market. I hope Synology roll out some performance class SSDs to compensate for this very soon.


 

UPDATE 2 (22/04) – I have been in communication with several representatives from Synology regarding this matter to get further clarification on this from them. The following statement was provided by a senior Synology representative and provided publicly with their consent :

 

“Synology’s storage systems have been transitioning to a more appliance-like business model. Starting with the 25-series, DSM will implement a new HDD compatibility policy in accordance with the published Product Compatibility List. Only listed HDDs are supported for new system installations. This policy is not retroactive and will not affect existing systems and new installations of already released models. Drive migrations from older systems are supported with certain limitations.

As of April 2025, the list will consist of Synology drives. Synology intends to constantly update the Product Compatibility List and will introduce a revamped 3rd-party drive validation program.”

Reason for the new Synology HCL Policy:

Each component in a Synology storage solution is carefully engineered and tested to maintain data security and reliability. Based on customer support statistics over the past few years, the use of validated drives results in nearly 40% fewer storage-related issues and faster issue diagnostics and resolution.

  • Each validated hard drive on the compatibility list undergoes over 7,000 hours of comprehensive compatibility testing across platforms to ensure operational reliability.
  • Technical support data shows that validated drives result in a 40% lower chance of encountering critical disk issues.
  • For models that have adopted the new hard drive compatibility policy, severe storage anomalies have decreased by up to 88% compared to previous models.

By adhering to the Product Compatibility List, we can significantly reduce the variances introduced by unannounced manufacturing changes, firmware modifications, and other variations that are difficult for end-users and Synology to identify, much less track. Over the past few years, Synology has steadily expanded its storage drive ecosystem, collaborating with manufacturing partners to ensure a stable and consistent lineup of drives with varying capacities and competitive price points. Synology intends to expand its offerings and is committed to maintaining long-term availability, which is not available with off-the-shelf options. We understand that this may be a significant change for some of our customers and are working on ways to ease the transition. Synology is already collaborating with our partners to develop a more seamless purchasing experience, while maintaining the initial sizing and post-install upgrade flexibility that DSM platforms are renowned for.” – Senior Synology Representative on the record.

 

Original Article:

Over the last few years, Synology have not been exact about being forward in supporting. Back in 2021, we started to see the brand reduce the number of third-party hard drives and SSDs on their systems. This diminishing support has manifested itself in two main ways. The first is that drives that are listed on the official support and compatibility pages have significantly reduced, favouring the utilisation of their own growing range of hard drives and SSD media. The second way this has presented itself drew significant criticism in 2022/2023, when utilising third-party hardware resulted in the system presenting warning messages and even service limitations being suggested. It appears that this is something they are putting into force for their new 2025 series of devices. Numerous websites in Germany have today reported that Synology plans to go full first-party drive priority on all systems released from the 2025 generation and onwards. An official statement from Synology via an official source has not been released, but it appears that the brand is going to go hard on pushing their own drives when using their own systems – at least at launch. So, what are the intended limitations for those who want to use non-Synology branded drives from Seagate and Western Digital? And why would Synology do this with their systems that have been open for over 25 years? Let’s discuss.

UPDATE #2 – There is now an official press release by Synology on this, available from Synology.de:

Synology is increasingly relying on its own ecosystem for upcoming Plus models Germany, Düsseldorf – April 16, 2025Following the success of the High-Performance series, the company is now increasingly relying on Synology’s own storage media for the Plus series models, which will be released starting in 2025. Users will thus benefit from higher performance, increased reliability, and more efficient support.  “With our proprietary hard drive solution, we have already seen significant benefits for our customers in a variety of deployment scenarios,” said Chad Chiang, Managing Director of Synology GmbH and Synology UK. “By expanding our integrated ecosystem to the Plus series, we aim to provide all users—from home users to small businesses—with the highest levels of security and performance, while also offering significantly more efficient support.”  For users, this means that starting with the Plus series models released in 2025, only Synology’s own hard drives and third-party hard drives certified according to Synology’s specifications will be compatible and offer the full range of functions and support.

There will be no changes for Plus models released up to and including 2024 (excluding the XS Plus series and rack models). Furthermore, migrating hard drives from existing Synology NAS to a new Plus model will continue to be possible without restrictions.  The use of compatible and unlisted hard drives will be subject to certain restrictions in the future, such as pool creation and support for issues and failures caused by the use of incompatible storage media. Volume-wide deduplication, lifespan analysis, and automatic hard drive firmware updates will only be available for Synology hard drives in the future.  Tight integration of Synology NAS systems and hard drives reduces compatibility issues and increases system reliability and performance. At the same time, firmware updates and security patches can be deployed more efficiently, ensuring a high level of data security and more efficient support for Synology customers.

TL;DR: Synology to Restrict Third-Party Drive Functionality on 2025+ NAS Models

Starting with the 2025 generation of Synology Plus series NAS devices, the company appears to be tightening restrictions on third-party hard drives. While you’ll still be able to use non-Synology drives (like those from Seagate or WD), early reports suggest that certain features may be limited or disabled unless you’re using Synology-branded or Synology-certified drives. According to preliminary reporting (not yet officially confirmed by Synology), using third-party drives may restrict (i.e several news reports indicate this, but no official statement/confirmation yet):

  • Creation of storage pools

  • Access to health monitoring tools

  • Volume-wide deduplication support

  • Drive lifespan analysis

  • Automatic firmware updates

  • Access to official Synology support

Older NAS models (up to and including 2024, excluding XS+ and rackmount units) are not affected. Drive migration from existing systems to new ones should remain possible — but full functionality may require Synology drives.

What are the proposed limitations of using third-party hard drives in the Synology 2025 lineup?

Although the brand themselves, at the time of writing, has not officially stated that devices after the 2025 series will only support their drives, sources highlighted on numerous news outlets have detailed that a number of key storage features and functionality are going to be limited. These include health monitoring tools, deduplication features built into DSM, official support from the brand in some cases, and (most worrying of all if it’s true) storage pool support. I’m still waiting for further clarification if this storage pool support limitation to first-party drives is only referring to the use of M.2 NVMEs in storage pools (something we are already aware of from the 2023 series), or whether people are not going to be able to use third-party hard drives in storage pools moving forward in 2025 series releases. But it would seemingly very much indicate the latter. It’s also worth highlighting that this limitation seems to be a ‘launch’ choice and may also mean that drives are granularly added to the supported pages as the likes of WD and Seagate submit compatibility reports. But the message seems to be that Synology themselves will not be the ones who verify the drive compatibility.

It should also be worth highlighting that users who have purchased devices before the 2025 lineup will not be currently affected by this change and will continue to have broader support of third-party hard drives, although even that has diminished since 2021–2022 as it stands. This does bring into question for some whether this broader policy is something that would be applied in a large-scale DSM update down the road, i.e. DSM 7.3 or DSM 8. For now, until we have an official statement from the brand or access to compatibility lists for the intended new products, we need to reserve our full judgement.

Why would Synology reduce compatibility with the majority of third-party hard drives (Seagate and WD)?

There are plenty of reasons why Synology would consider a move like this, for good and for bad. So in the interest of balance, let’s start positive. What are the good reasons why Synology would endeavour to only support the use of their own storage media in their systems?

  • To a much smaller group, it allows them to tailor performance and system deployment expectations a great deal more realistically and could result in improved overall performance for all users, as it allows the development of future solutions to be significantly more targeted.
  • If Synology solutions only support Synology drives, it allows the brand to be a great deal more effective at reducing the TCO of the system to buyers, as it will be an all-in-one party solution and even opens the door to the brand rolling out bundled systems that will further reduce the total cost of ownership.

  • Export costs in the US — Synology centralising the full component list of their products to the end user can also allow them to better absorb any potential costs efficiently and hopefully pass those cost savings onto the consumer, reducing reservations on purchasing the product in light of potential price hikes.
  • Support will be a great deal more specialised if end user deployments have fewer variables to consider, resulting in reduced support resolution times and potentially improved support services as an end result for all users.

Beyond the other potential benefits, they will be considering this proposition to drastically reduce third-party hard drive compatibility and utilisation in the 2025 lineup:

  • In a word, profit. Having their own storage hard drives as the main — and potentially only — storage option alongside their systems will allow the brand to make profit vertically across the product deployment. For a long time, the brand was only really monetizing the core system itself, which is really only going to be replaced every 7 to 10 years for most users. Storage media, given the escalating growth rate of people’s data, will require a great deal more regular replacement.

  • If Synology storage media is largely the only option to buyers, the brand has a greater degree of control over which products are available. So, for example, currently Synology has fewer different capacity tiers and drive variation tiers compared with other brands (i.e. 24TB drives, surveillance-optimized drives, M.2 NVMEs built for performance, etc.), so in some cases a user may have to opt for a larger capacity or a more enterprise-class drive when they might not need to.

  • Eliminates smaller-scale purchases. This is a particularly cynical point of view, I know, but a move like this will almost certainly push value series devices significantly more towards the likes of the BeeStation (which are already pre-populated and fixed with Synology storage media) and away from the Plus series, as a divide begins to appear in terms of the overall total purchase price for many users. Alongside upselling their value series to that buyer tier, it will also move only more serious buyers towards the Plus series and higher from 2025 onwards.

All of the above reasoning towards why Synology would prioritise their own drives over that of third parties are my own points of view, but I do think there’s a ring of truth in some of them.7

What are the potential problems surrounding Synology’s push toward its own storage media over third-party drives?

There are several small issues that are worth highlighting in this broader plan of Synology hard drive prioritisation that we should probably touch on — and hopefully ones that Synology themselves will resolve quickly if this is something they’re going to push hard on. Such as:

  • The brand inadvertently revealed earlier this year that they are working on a 6 x 2.5-inch SATA SSD system called the DS-625 Slim. However, the only 2.5-inch SATA SSD media the brand has are way too enterprise — the SAT5200 series — and would be like putting a Ferrari engine into a Ford Focus in terms of the disparity in the hardware being used and the price point!

  • Synology has still yet to introduce higher-performing M.2 NVMe storage media, and although several of the new 2025 series of devices arrive with M.2 NVMe support, Synology’s own M.2 SSDs prioritise durability over performance. That is a good thing, but users who are not going to be able to use third-party SSDs for caching or storage pools face being restricted to much lower-performing SSDs in these bays.

  • How will the system identify the use of third-party drives, and to what extent are these drives going to be limited? Although lots of details have been revealed in the news reports today, we’re still yet to see a full detailing from Synology themselves on an official platform.
  • Surveillance utilisation. Synology has an impressive range of surveillance solutions in the NVR and DVA series, as well as support for Surveillance Station on the majority of their systems, but to date, the brand still does not have surveillance-optimised hard drives in its lineup. Surveillance-optimised hard drive media like WD Purple are designed to have much higher write performance leveraging rather than read, and surveillance drives are generally only accessed for a very small percentage of the time when in use. Will third-party drive limitations extend to these systems as well?

I’m still waiting on an official Synology response on this matter, as there have been early indications (such as the Synology DS925+ Amazon.co.uk link 2 days ago) that indicate some of these systems may be arriving in May 2025 — not that far away! So, until we have full and officially backed confirmation on this, still treat it with a grain of salt. I’d be lying if I said I wasn’t a little disheartened by this move by the brand, as although their software is still absolutely the king of the hill in the world of NAS, further restrictions on their more modest hardware to only use their own range of hard drives — versus that of more widely available, globally distributed, and industry veteran–backed drives — seems a very odd move, and one that I think a lot of home/prosumer/enthusiast/SMB users might take issue with.

Synology DS925+ NAS Leaked (AGAIN)

Par : Rob Andrews
14 avril 2025 à 16:00

The Synology DS925+ NAS is (STILL) Coming..and Soon

It is fast becoming the worst-kept secret in the world of network-attached storage, but Synology’s continued plans to launch refreshes of a number of their popular desktop devices received another public outing this weekend, when keen users on Reddit spotted the official pages for the Synology DS925+ and DX525 on Amazon.co.uk, listing hardware specifications, pricing, release dates, and general background info. Although the appearance of the DS925+ isn’t exactly surprising—given the large info drop semi-officially revealed at an official event by a user on Chiphell—it is nonetheless surprising to see these two official Synology products seemingly added by Synology themselves for Amazon distribution, yet with absolutely zero mention on the traditional Synology platforms (Synology Products, Synology Downloads, Synology Download Registry, etc). Nonetheless, this appearance has confirmed numerous details about the DS925+ hardware specifications, for good and for bad, so I wanted to go through the further confirmed specifications and what they mean.

Synology DS925+ NAS Confirmed Hardware Specifications

As previously alluded to last month in the previous leak, the Synology DS925+ will arrive with the already integrated CPU from AMD that featured on previous SMB releases—the V1500B. This is a quad-core CPU that allows for more cores, more threads (i.e. more vCPUs) than the R1600 in the DS923+, as well as a lower TDP—though also a lower total clock speed available at first. It arrives with 4GB of ECC memory that can be scaled up to 32GB via two SODIMM DDR4 slots. DS925+ includes 2 × 2.5GbE, a very welcome if somewhat overdue upgrade on this product series from Synology. The SSD compatibility for storage pools and the speed allocated to each slot is still TBC. The expansion capabilities of the DS925+ have changed from the long-running eSATA support and DX517 of older Synology devices and now lean towards popular USB-C, and this is what triggered the new DX525 expansion box. We are still awaiting confirmation of the confirmed speed of this USB-C port, as well as its broader compatibility for other things (given the larger variety of USB-C options available in the market compared with eSATA), but slides shown at the Synology partner event last month seemingly indicated that this will NOT be USB 3.2 Gen 2 10Gbps.

Probably the biggest and most controversial change here in the newer generation box is the removal of the mini PCIe upgrade slot that featured on the DS923+. The new DS925+ completely lacks this ability to scale up to 10GbE later down the line, which is probably going to upset a lot of users. PCIe modules they have sold (which would greatly explain, perhaps, the motivation for removing this feature), it is still something of a blow that this new generation device has removed a particularly appealing network upgrade path option. The motivation for this could be theoretically for multiple reasons, such as:

  • Synology might well have deemed the two-times 2.5GbE network connectivity on the DS925+ sufficient for the four drives of SATA storage that it features, as well as ensuring that the system does not overlap other devices higher in the product portfolio food chain too much.
  • The PCIe line distribution of this CPU and the chipset used on this board might result in limitations to the distribution of those lanes and therefore made the upgrade difficult to implement.
  • The USB-C port for expansions may support a 10GbE upgrade module down the line that Synology intend on rolling out—a bit of a long shot though, as currently USB-C to 10GbE is only afforded to TB3/TB4/USB4 connectivity and would commit a great deal of internal lane distribution to that port to accommodate this potential upgrade.
  • As previously alluded to, perhaps user integration of this upgrade slot on previous DS923+ devices was too low to justify accommodating this feature in the newest iteration.

Any of those reasons, or others, might well be why Synology decided to rescind this feature on this device. Nevertheless, it is something of a bitter pill that this device will not be featuring the ability to scale up out of the potential 5GbE bonded network connection that it arrives with and likely serves as a slight bottleneck to more high-performance hard drives in the SATA bays, as well as a significant cap on using SATA SSDs or M.2 NVMes in storage pools via the provided slots.

The AMD Ryzen R1600 and V1500B are both embedded CPUs used across Synology’s NAS lineup, but they serve distinct roles depending on the target user and workload. The R1600 is a dual-core, four-thread processor with higher clock speeds (2.6GHz base / 3.1GHz boost), making it ideal for environments that prioritize single-threaded performance—such as general file sharing, light server tasks, and basic backup operations. It has a TDP of 25W and is commonly found in more entry-level to mid-range Synology NAS models like the DS723+ and DS923+. By contrast, the V1500B is a quad-core, eight-thread CPU running at a lower base clock of 2.2GHz, but it delivers greater efficiency and significantly better multi-threading performance—essential for virtual machines, Docker containers, multiple user sessions, and parallel workflows. Its lower TDP of 16W also makes it a more efficient option for always-on deployments in business settings.

CPU Comparison: AMD Ryzen Embedded V1500B vs R1600

Specification AMD Ryzen Embedded V1500B AMD Ryzen Embedded R1600
Cores / Threads 4 Cores / 8 Threads 2 Cores / 4 Threads
Hyperthreading Yes Yes
Base Frequency 2.20 GHz 2.60 GHz
Turbo Frequency (1 Core) Not Supported Up to 3.10 GHz
Turbo Frequency (All Cores) Not Specified Not Specified
Overclocking No No
TDP 16W 25W
Cache (L1 / L2 / L3) 384KB / 2MB / 32MB 192KB / 1MB / 4MB
Socket Type BGA1140 BGA1140
Architecture Zen (Normal) Zen (Normal)
CPU Class Embedded / Mobile Embedded / Mobile
First Seen Q2 2021 Q4 2022
Single Thread Rating (CPUBenchmark) 1230 (-28.7% vs R1600) 1724 (Higher)
CPU Mark (Overall) (CPUBenchmark) 4829 (Higher) 3276 (-32.1% vs V1500B)
Estimated Yearly Power Cost $2.92 $4.56

What makes the V1500B particularly notable in the DS925+ is that this CPU was previously reserved for Synology’s larger SMB and enterprise-tier systems, such as the DS1621+, DS1821+, and DS2422+. By introducing it into a prosumer-class 4-bay NAS, Synology is clearly continuing its long-standing trend of moving mature hardware platforms down into lower product tiers over time, as the cost of components becomes more accessible and manufacturing scales improve. This strategy enables Synology to offer higher-tier performance at mid-tier price points, effectively refreshing their product range while maintaining price consistency. For users who prioritize multi-tasking, virtualized workloads, or long-term scalability, the arrival of the V1500B in the DS925+ marks a significant shift in capability for this tier of NAS.

Want to Understand How Synology NAS Product Refreshes Work, as well as Why Synology Chooses Certain Hardware? Read my article below:

Synology DS925+ NAS HDD and SSD Compatibility?

Unfortunately, there is no mention of Synology’s position on third-party hard drive and SSD compatibility on the new DS925+ confirmed yet. Realistically, basing it on the predecessor and other Synology Plus Series devices, at the very least, we’re going to see a repeat of the priority towards Synology’s own series of hard drives and SSDs, with a handful of third-party drives from Seagate, Western Digital, and Toshiba added to the support list. This has now become the status quo with the majority of Synology Plus Series and above devices, and if this device rolls out with that, I’m not going to say that it’s perfect, but at the very least it does still leave a narrow window open for users to use third-party hard drives without the system spitting alerts or amber warnings at you during setup.

As the system is being listed on the Amazon pages without drives included, that at the very least removes the concern of many that Synology may have been proceeding down the pre-populated system route, or being more rigid on the lock-in of the drives you can use on the system. Nevertheless, there is still the matter of the M.2 NVMe slots and whether this system will continue with the policy of third-party drives only being supported for use as caching, whereas Synology’s own M.2 NVMe drives support both caching and storage pools. It will most certainly continue with this position.

Synology DS925+ NAS Price and Release Date?

As originally predicted last month, the pricing of the DS925+ will be largely the same as that of the DS923+, as Synology is always keen to maintain the pricing at each tier of its portfolio year on year—even if sometimes that can result in the hardware being a little more lean despite the cost of components going up. I kind of respect how long Synology has been able to maintain the same price for their prosumer 4-bay device, right? All the way back since 2015, it has always arrived at that similar £550 price. Keep in mind that the price listed on the early leaked Amazon.co.uk page includes VAT, whereas pricing listed in other countries like the U.S. will likely not include tax.

With regards to the intended release date and availability of the DS925+, the Amazon leak page appears to indicate the 7th of May. Now, whether this has always been the plan by the brand when refreshing all of its currently existing product line, or it is a launch date that has been changed rapidly in light of discussions surrounding tariffs and stock travelling around the world, is yet to be confirmed. Nevertheless, that seems like a fairly reasonable launch date in light of the information—originally appearing online with the product page added to Amazon on April 8th—and the slow but steady gear Synology goes through when making a product live across traditional online retailers. You can use the links below to monitor the availability and price of the Synology DS925+ on Amazon, as it will redirect to your own region via the link.

Synology DS923+ vs DS925+ NAS – Buy Now or Wait?

When comparing the Synology DS923+ and DS925+, the differences are subtle but important depending on your priorities. Both NAS units share the same price point, run Synology’s DSM software with identical features, and include the same baseline 4GB DDR4 ECC memory (expandable up to 32GB). They also both lack integrated graphics, feature four SATA drive bays, and offer two M.2 NVMe Gen 3 slots for SSD caching. However, the DS925+ gains an edge in raw parallel processing power, featuring a quad-core, eight-thread AMD V1500B CPU, which translates to more virtual CPUs (vCPUs) for virtual machines and containerized applications. It also benefits from dual 2.5GbE ports, enabling up to 5GbE performance with Link Aggregation or SMB Multichannel, compared to the 2x 1GbE ports on the DS923+, which top out at 2GbE combined. Additionally, the DS925+ offers a faster expansion interface via USB-C (6Gbps) versus the older eSATA (5Gbps) on the DS923+.

Estimated Price ~£550 ~£550
Warranty 3 Years (5 Years with Extended Warranty) 3 Years (5 Years with Extended Warranty)

That said, the DS923+ still holds certain advantages. Its AMD R1600 CPU features a higher clock speed, which may offer better single-threaded performance in lighter tasks or low-concurrency applications. Crucially, the DS923+ supports an optional 10GbE upgrade via its mini PCIe slot, a feature completely removed in the DS925+, which could be a deal-breaker for users planning to grow into a higher-speed networking environment. So, should users buy the DS923+ now or wait for the DS925+? If 10GbE upgradeability or faster per-core performance is important for your workload, the DS923+ is still a strong option. However, if you’re prioritizing multi-threaded performance, better default network speeds, and a more modern expansion standard, the DS925+ is the more forward-looking choice—particularly for virtualization and container-heavy environments. Ultimately, both devices serve the same class of user, but choosing the right one depends on whether your focus is scalability or efficiency out of the box.

Synology DS401+ Drive Review

Synology DS401+ Review: A Big Leap in Data Portability

Synology has once again redefined innovation with the launch of its latest device, the DS401+, a radical departure from traditional NAS design. Unlike anything in their existing lineup, the DS401+ is a compact, ultra-portable single-bay system that arrives with 8GB of pre-installed storage.

While its modest appearance might lead some to question its capabilities, this device is full of surprises and packed with what Synology describes as “next-level user-driven expandability.” Upgrades are a breeze, requiring nothing more than confidence, persistence, and maybe a little brute force.

Connectivity is as streamlined as it gets, with USB 2.0 ensuring compatibility with virtually every system released in the past 20 years.

Performance skeptics will be pleasantly surprised to learn that the DS401+ boasts transfer speeds of up to 8GB per second—a metric achieved under rigorous, real-world conditions involving trajectory and velocity.

While traditional benchmarks focus on read/write speeds, Synology’s new direction explores the physics of momentum as an alternative measurement of data mobility. One of the standout features of the DS401+ is its offsite backup functionality.

Designed for those constantly on the move, users can effortlessly transfer data, pop the DS401+ into a bag, and take their backup anywhere—whether that’s to work, the grocery store, or an accidental adventure sparked by a missing cat collar, missing your train and leaving your bag at home – can’t question it, that’s a pretty solid off-site backup!

While the DS401+ doesn’t support DSM, Synology’s usual operating system, it does come with pre-installed software of a different nature. Details remain scarce, but early reports suggest a mysterious blend of anti-ransomware tools, possibly paired with rudimentary antivirus protection.

Whether this is a security feature or just a cleverly disguised README file remains to be seen. Nevertheless, the DS401+ clearly takes a bold stance on cybersecurity—even if no one knows exactly what it’s doing.

File sharing has never been more intuitive. With the DS401+, users can now share files simply by passing the device to someone else. There’s no need for network mapping, no passwords to remember, and absolutely no waiting for uploads. This tactile approach to data transfer offers unmatched immediacy and person-to-person encryption powered by trust. For those concerned about future expansion, Synology has teased a “Forb” edition, rumored to support even more aggressive upgrade techniques.

And for power users who demand more from their tiny NAS, Synology has introduced the DS401+ Forb, a “four-bay” variant that somehow fits into an even smaller form factor than the original. Early hands-on impressions describe it as “smaller than the palm of your hand but twice as confident.” While there’s no visible evidence of four bays, Synology assures customers that the extra capacity is there if you’re willing to think small enough. Expansion remains as simple as ever—just apply additional USB drives using light percussion.

The launch date of the Synology DS401+—April 1st—is no coincidence. Known globally as April Fools’ Day, it’s a time when tech companies occasionally tease products that walk the line between absurdity and brilliance.

From its minimalist design to its unconventional “performance” metrics, every detail feels like a carefully crafted nudge and wink to the audience. It’s a playful reminder that innovation sometimes requires not just thinking outside the box—but joking about the box entirely.

New Synology NAS for First Half of 2025 Revealed – DS925+, DS1825XS+, DS625Slim, DS1525+ and More

After what seems like quite a while for many, we have finally got pretty large confirmation that Synology are refreshing a large number of their Desktop (and a couple of Rackmount systems) devices – as well as launching a few new storage media options. This new information arrives via ChipHell user ‘nineeast‘ in a recent forum post. I am still in the process of identifying the event that the photo below was taken from, but given the preponderance of people taking photos, it won’t be long before this spreads further. This is of course the potential that this is a hoax… but (as you will see later in the article) the chiphell post is not the only source. Nevertheless, it looks like Synology are getting set to refresh a huge number of solutions, launching their DS925+, DS425+, DS225+, DS1525+, DS1825+, DS725+, DS625slim, DS1825xs+ and RS2825RP+ between now and Summer 2025. So, let’s discuss what these refreshed devices bring and whether they deserve your data.

*Update* In order to better track each of the new Synology NAS revealed at this event, I have made update pages for each device below. Additionally, as mentioned in the video, I am canvassing user feedback on these new releases (ideally existing Synology NAS users and/or SIs – system integrators) for a follow up video soon. put your feedback in the comments below or in the Reddit thread HERE

Which Synology Solutions were Revealed at the Synology Event?

The big deal here is that it is tremendously rare for Synology to reveal their roadmap of solutions, let alow share it with users in such a detailed fashion. Synology have always been tremendously restrained when it comes to revealing their product refreshes (and new product lines). That said, refreshes of products in their portfolio periodically is pretty normal, and most Synology solutions will see a refresh every 2.5-5years (depending on the product tier, with XS series devices generally having a longer refresh cycle), and many have been wondering about when a refresh to the x22/23 range of devices would arrive, and in what form it would take. The TLDR list of solutions shown were:

DESKTOP SOLUTIONS RACKMOUNT SOLUTIONS EXPANSIONS MEDIA
DS1825+ – AMD V1500B, 2.5GbE ×2

DS1525+ – AMD V1500B, 2.5GbE ×2

DS925+ – AMD V1500B, 2.5GbE ×2

DS725+ – AMD R1600, 2.5GbE ×1

DS625slim – Intel J4125, 2.5GbE ×1

DS425+ – Intel J4125, 2.5GbE ×1

DS225+ – Intel J4125, 2.5GbE ×1

DS1825xs+ – AMD V1780B, 2.5GbE, 10GbE + OOB

RS2825RP+ – AMD V1780B, 10GbE RX1225RP – Suitable for certain RS series devices

DX525 – Suitable for certain DS series devices

SNV5420 Series – M.2 2280 NVMe

SAT5221 Series – 2.5” SATA SSD

HAT5310-12T/16T – 3.5” SATA HDD

HAT5310-4T/8T – 3.5” SATA HDD

HAT3320-8T – 3.5” SATA HDD

The biggest takeaway in these shared images seems to be that the bulk of the solutions in this 2025 year refresh are going to remain largely the same, but with two main changes across the board.

Credit to nineeast on Chiphell forum

Thise changes are 1GbE network interfaces will be upgraded to 2.5GbE interfaces universally, and expansion devices that would have previously used eSATA as a means of connectivity will now be USB-C (as well as a reshuffle of the CPUs in the product tiers/families around), but we will get onto that latter point in a moment. Further information and images have also been shared by user ‘ERROR204‘ on imnks, another storage *& network related forum, as well as bringing further information on the expansion devices. The DS1525+, DS925+ and DS725+ will serve as refreshes of the DS923+, DS723+ and DS1522+ NAS. It’s unclear whether they will be using that mini PCIe upgrade card like the existing series (the E10G20-T1-MINI) as the slide below indicates that they will not, but the DS925+ and DS1525+ will see the R1600 Dual Core / 4 Thread Ryzen processor in their predecessor replaced with the v1500B 4 Core / 8 Thread CPU (previously used in the 6/8/12 Bay desktop NAS devices. The DS725+ however will remain as the R1600, but will see the 1GbE NICs upgraded to 2.5GbE.

Credit to ERROR204 on imnks.com

Interestingly, the default memory on the DS725+ will increase to 4GB of ECC Memory (as opposed to the 2GB in the DS723+ predecessor). However the slide below also indicates that it will no longer support the mini PCIe 10GbE adapter. So it’s a mixed bag in the DS725+ refresh really. This slide also indicates that the USB-C connected expansion will seemingly remain at 6Gb/s transfer speeds – which is a little odd, given USB 3.2 Gen 1 is 5Gb/s and USB 3.2 Gen 2 is 10Gb/s – something to ponder.

Credit to ERROR204 on imnks.com

Next is the ‘media’ series of devices and also a return of the Synology SLIM series. The DS625slim arrives (refreshing the DS620slim from 2020) and the DS425+ and DS225+ arrive as refreshes for the comparatively (for Synology’s MO) new DS224+ and DS423+ NAS. These will be continuing to use the existing Intel J4125 Quad Core Celeron CPU from 2019/2020 (something I know will not please everyone), but will also see upgrades to 2.5GbE from the 1GbE on their predecessors. Additioanlly, I think we can assume the DS425+ will have the 2x M.2 NVMe slots of it’s predecessor.

Now the DS925+ (a refresh of the DS923+) has the upgrade from the R1600 CPU to the V1500B CPU we mentioned earlier, alongside the new USB-C expansion support (the DX525) and 2.5GbE NICs, so I think we can assume the DS1525+ will be similarly reprofiled from the DS1522+, but I am unsure if it will have 2x USB-C ports instead of 2x eSATA (almost certainly, but not 100%). I think many user are going to have mixed feelings once again about the CPU choices present here in the bulk of these new refreshes.

Now onto those two 8 Bay devices, the DS1825+ and DS1825xs+ (serving as refreshes of the DS1821+ and DS1823xs+ respectively). As covered in my video in 2024 about previously leaked information on the DS1825+, it seems that both of these devices will have the same CPU as their predecessor devices, but will see upgrades from their 1GbE ports towards 2.5GbE (with the DS1825xs+ maintaining it’s 10GbE copper connection). All other specifications (M.2 slots, expandability, memory, etc) will all seemingly remain the same – though I think we can once again assume that expansion ports will be USB-C in line with the DX525 box.

For many, it will be a little disappointing that we did not see a 6-Bay model arrive and in fact there has not actually been a 6-Bay Synology NAS since 2020 (when the DS1621+ and DS1621xs+ were launched), increasing fears that Synology are eliminating that tier of their portfolio. However, there is ZERO confirmation on this and the 6 Bay option in the Synology store is still present for the DS1621+ and DS620slim, though the DS1621xs+ has disappeared (likely replaced internally with the 8 bay XS option).

 

Finally, there is the storage media that was listed. Some drives we already knew about. For example, the SAT5221 Series of SATA SSDs already appeared on vietcorp (HERE), but the HAT3320 is seemingly a refresh/new line in the Synology Plus series of hard drives – and there have been rumours circling for a while that these would be Seagate Ironwolf drives, but currently unconfirmed.

Finally, there is the Synology SNV5420 series – a new M.2 NVMe media drive range, but it is currently unclear if this is a complete refresh of the SNV3400/SNV3410, or as the naming convention seems to indicate, a higher performance/class of M.2 NVMe SSDs. This is something that has been LONG DEMANDED as Synology still have a solid insistence on their systems/add-on cards with M.2 NVMe Support HAVE TO be their own media drives if you want to use the slots of Storage pools, yet the SNV3400 range and it’s variations are comparatively low speed and high priced vs the rest of the M.2 NVMe SSD market as a whole.

So, that’s everything we know so far. Let’s now discuss what we think together in the comments!

The New Synology 2025 Product Line Up – What I Like and What I Don’t!

I have mixed feelings about the entire Synology refreshed line up – on the one hand I DO think there is a meaningful refresh here on the DS925+ and DS1525+ NAS. No one was expecting Synology to completely change this product family, as they have already made it pretty clear that these two system profiles are designed now more for the SMB user, small business, container deployer and those with file processing needs – i.e not multimedia as the focus. So, them upgrading this from the R1000 CPU in the x23 series to a V1000 CPU (doubling the cores and threads) will be tremendously welcome – as will 2.5GbE out the box (though I would like more clarification on the E10G22-T1-MINI 10GbE upgrade card support – as it looks like this is now not supported and that would be a real shame). Also, as much as its a bummer to see the V1500B CPU that Synology have already had on their products in 2020 in these 4 and 5 Bay solutions, they ARE good follow up CPUs over the R1600 in profile, and still have a length support time with AMD backing them up. All that said, the DS725+ seems pretty hard done by here, in fact the DS425+, DS225+ and DS725+ all seem to essentially be the same NAS, but with the 1GbE NICs swapped out with 2.5GbE. I mean, if the price remains exactly the same as the DS423+, DS224+ and DS723+ (and no other hardware surprises arrive in the form of no NVMe slots, etc), then these are…technically…refreshes. But more like a DS224+II, than a whole new DS225+.

Regarding the Intel Celeron devices, I am a little puzzled more than anything else. 2.5GbE on these is good (even if we overlook the fact that 2.5GbE has been fairly standard on ALL NAS systems in place of 1GbE since 2020 from everyone else), but the J4125 CPU is a CPU that has long since retired by Intel (indeed, Intel Celeron naming itself is long gone in favour of the Alder Lake and Twin Lake N processors). So unlike the strong support afforded to the AMD processors I mentioned above, the J4125 seems a remarkably dated choice right now. Still, better some kind of graphical capable CPU in the line up than none at all. Still, odd choice. As there are a lot of holes in these specifications, it’s tough to make a full list of what is good and bad, plus we have to acknowledge that things CAN change during development. So, I’ll hold off for now with anything concrete on my own thoughts, but again, I would love to chat in the comments here or on YouTube for your own thoughts.

Things we still need confirmation on!

As I just mentioned, there are still a lot of gaps in these specs and till we have the full picture, we can’t judge anything! So, here are the questions I still have about these new refreshes that remain unanswered for now:

  • HDD and SSD Compatibility, will it be largely the same as the existing 22/23/24 series devices (i.e largely Synology drives, but a few Seagate/WD/Toshiba drives), or will these new series be the first to arrive with strict Synology-only drive media and/or pre-population?
  • How is the USB-C 6Gb/s? Is it an adapter, or a USB-C Port on the old lane internally?
  • Where is the 6-Bay?
  • Ambiguity at best, complete removal at worst, of the 10GbE upgradability of the 2/4/5 Bay V1500B option NAS’. Is this for real?
  • Is the SNV5420 a new high performance M.2 NVMe?
  • Why refresh all of these at the same time? Some solutions like the DS1823xs+ or DS224+ are very early in their expected run, so a refresh so soon seems unnecessary. So why now?
