Synology DS925+ NAS Leaked (AGAIN)

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

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. Anything purchased via these links will result in a small commission to me (Robbie) and Eddie at NASCompares, which really helps us keep doing what we do.

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

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.

Credit to ERROR204 on imnks.com

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.

Credit to ERROR204 on imnks.com

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?
