The Synology DS725+ is an odd placement. It is a great device for most, don’t get me wrong, but with a seemingly downgraded Network port, the same CPU as a past model, no PCIe expansion port to upgrade to a 10GbE network port, and still an expandable storage option, it makes this a hard device to suggest, even while it’s a great device on it’s own.
As a device, not looking at models from the same company or family, this would probably score a bit higher. But knowing that other models exist at a similar price point from the same reputable company with better features, this score gets knocked a bit.
But with that said, the last thing I will say, with other products in mind, is that the DS723+ may be the better option for you if you need the 10GbE option or want it in the future; however, not everyone will want or ever really need that kind of speed. So, it depends on what you are going to use this NAS for.
Synology DS725+: Price and availability
The Synology DS725+ without drives sells for $499, giving you an empty case ready for whatever drives you want. You can choose to add just one drive, or fill both bays, and you can also fill the M. 2 NVMe slots. If you want more storage, you can grab an expansion DX525 unit and add 5 more bays, bringing the total to 7.
It's widely available right now direct from Synology and online retailers like Amazon.com and Amazon.co.uk.
Synology used to require Synology-branded drives for compatibility, but they have recently opened this up to allow for non-Synology drives, just noting that not all will function the same.
For example, I have 2 Synology M.2 drives in my NVMe slots for caching, and for my main drives, I have 2x 8TB Seagate IronWolf NAS Internal Hard Drives, giving me a total of 16TB of storage, plus the 800GB of caching. This option was cheaper than the Synology-branded drives, and so far, I have had no issues.
Synology DS725+: Unboxing and First Impressions
Synology is one of those companies that has simple packaging, and at this point in my life and professional career, I appreciate that. No need for flashy packaging, just let me get to the product and let the product speak for itself. There are some nice foam inserts to help ensure the enclosure doesn’t get damaged, along with the power brick and cable, some RJ-45 LAN cables, drive bay screws, a key, and the guide.
This enclosure is super minimal, and with the NVMe slots under the device, the overall footprint is pretty small. I was able to add this to a small rack pretty easily, even though this is a desktop model, not a rack-based model. For this current setup, a rack system works well, but for the future, I want the flexibility of putting this on a desktop, making this formfactor perfect for me.
I was able to get things set up pretty quickly, not having to follow any instructions other than confirming the best way to connect to the NAS for the first time. Setup all occurs over at find.synology.com, which I've also used for my other Synology drives, and I was good to go.
For this setup, I have the Synology DS725+ 2.5GbE network port plugged into a Zyxel network switch that also has two media computers connected, and that switch is connected to my LAN. I also have a redundant network line for any potential failover running from the 1GbE port directly into the building.
Once I got that squared away and installed all four drives, I plugged in power and booted it up, then visited find.synology.com to install DSM and set the parameters I wanted. The setup was pretty straightforward, and there were no spots where I felt confused or unsure about what to choose. It probably took about 15-20 minutes from unboxing to using and syncing files.
Synology DS725+: Design & Build Quality
The physical design of the Synology DS725+ is pretty simple, and I like that. It’s not trying to be flashy. I do wish Synology would adopt more ports on the front for file transfer, as other companies like UGREEN do, but it’s not the end of the world by any means.
For this kind of storage, I understand why they don’t make it the primary focus, as the user base would probably be those who are not in the media space or have other ways of ingesting footage. Though I was able to easily ingest SD cards via an adapter, which was a fun surprise.
This is the kind of NAS you can, of course, tuck away if desired or keep on your desk, and you won’t feel bad about it at all, as it looks clean and sleek with its matte dark grey/black colorway and minimal lighting and badging.
Speaking of the looks, the build quality is great on this; there are no loose pieces or elements that feel cheaply designed. Everything feels quality without feeling so nice that I shouldn’t use it. Sadly, again, there is no expandable PCIe Gen 3 port, but there is an expandable USB-C port on the back for an expansion bay if desired down the road.
One thing that was updated since I received this unit and started testing is that Synology now allows all drive types again. While I do understand the backlash Synology was getting for this move, I see it as a lot like Apple's walled garden.
Yes, there may be part of it that is for trying to make users spend more on their products, but Apple is very particular about what can and will go into their devices, so they can have more control of the outcomes, producing a reliable experience which they could not ensure with products they do not design.
I think Synology was trying to ensure the best performance by only allowing its drives that meet its standards and performance expectations, not just any drive. However, now you can add just about any drive. Synology just notes that it may affect your performance, so make sure you do some research before choosing a non-Synology drive.
Synology DS725+: In use
I’ve had this drive up and running in my team’s media area for several weeks now. Its primary use is as a media server, hosting RAW video and photo files, communicating with a DaVinci Project Server, and working as a sync between Macs and Google Shared Drives, as well as other media folders scattered about. We rely on the cloud sync functionality to keep everything in check, uploading and downloading as needed.
Synology’s DSM 7 software is so easy to use that I can connect to it and work from my iPhone, my iPad, my Mac, or just interact with the file server through Finder. It is incredibly easy to set up and work on.
Right now, I have one volume containing all 16TB of my storage drives, and then both of my NVMe drives are set to cache that volume, making for one big drive that can work as fast as I need it to. I may add another set of drives through the expansion bay in the future and set up another volume, or I may split this volume over time depending on usage, but what’s great is that Synology makes that super easy.
If media storage is not what you need this for, this is even better as a file server, acting as your source of truth, a RAID server that can backup your critical files, or even work as a hybrid with a cloud service, backing up your cloud files, your computer files in the field, or perhaps taking what you store on a more expensive, but sometimes more convenient cloud service, pulling it down to your cold storage Synology backup, and freeing up your more convenient cloud service storage. Either way, this system is fantastic for all types of storage management.
Synology DS725+: Final verdict
I’ve only touched on the DS725+'s capabilities, which speaks to just how capable it is. However, circling back, its product placement is a bit odd. So, if you are looking for a great NAS for your business professional use, then you should probably check out the DS725+ as well as some of the other DS systems that Synology offers, but if you find a great deal, and you are ok with a 2.5GbE max port, then you should absolutely consider grabbing the DS725+ for your business or use case.
As most things do, this purchase comes down to the right deal and the right use, but at the end of the day, Synology is still highly respected in this space, and for good reason. They make great gear, even if some of it is oddly positioned against its brothers and sisters.
