I’ve owned a synology DS nas for over a decade with no problems. Decided to get a new one because I didn’t want to have to start upgrading all the existing 8tb drives as I would have to buy 3 20tb drives just to start getting more storage. Some people stated that this only accepts Synology drives. I don’t doubt that they would do that because of greed. But I was able to use WD Red Pro drives. They are far from cheap but they were properly detected and setup. It does say that they are not on the compatibility list and they won’t guarantee compatibility but everything works up front. Obviously it updated the OS before I did anything so perhaps they loosened the restrictions on drive compatibility I know in my old DS I was able to use Green drives but mostly use the Red drives now days. I will not be able to talk about longevity on this model as I wouldn’t expect any issues for years. As my old unit just turned 13 years old and is still running just fine. The only problem it has is not compatible with future OS upgrades as my old unit is now to old.

UPDATE: I have been up for about a month with no issues. I added the 2 port 10GBE card, which didn't really increase transfer speeds. It took a while to get all of the certificates transferred from my old NAS to this one, but that is complete. My opinion remains that Synology makes the best once things are running you can forget it NAS units. I was running out of room in a 6 bay 1621XS+ NAS with all bays filled with 16TB drives. Thanks to drive shortages, it is cheaper to purchase a new NAS with more bays and add a spare drive than purchase 6 20TB drives to gain similar storage space. I had read about the Synology 3rd party drive drama. I also read about Synology reversing the decision for the DSxx25+ series units. I would not be surprised if Synology forces the 3rd party drives issue in future NAS releases as the company is focusing attention on servers and data centers instead of home and prosumer users. The basic features of the 1825+ are equal or less than my 5 year old 1621xs+ NAS it is replacing. I am downgrading an Intel 4 core Xeon D-1527 server processor for an AMD desktop processor and native 10GB ethernet for 2.5GB connectivity for two more bays. I do not have virtual machines or use docker and thus was underutilizing my server processor. I rarely transfer enormous files other than wired backups to another NAS. If 2.5GB ethernet becomes too slow in the future, I can upgrade to 1 or 2 10GB ports with an expansion card. The 5 year old RAM and m.2 SSD in my old NAS are the same as the new models making it easy to upgrade the 1825+. This gives me 32Gb of RAM and 2 400Gb m.2 SSD. Some may say that is not a good thing. It is clear that Synology is more focused on great user interface and reliability and less focused on the latest and fastest components. I do find the larger fans on the 1825+ to be an upgrade. 120mm fans will move more cubic feet of air than 90mm fans. This will extend drive life. Also, 120mm fans spin slower while maintaining airflow which will reduce noise. Unless you turn the fans up to full speed, the loudest thing is the hard drives. I had no issue migrating my RAID with 6 16TB Seagate Exos x16 drives to the new NAS. I then expanded the RAID with a 7th Seagate Exos drive. Synology does give a petty message that I am using drives that are not on the compatibility list, but it no longer gives RAID instability warnings or turn the drive indicators orange. You have access to all SMART data in the disk utility software. Other programs, such as surveillance station, do not share drive information. I understand Synology doesn't want a user to install desktop drives, but Enterprise drives from a reputable manufacturer? That is just plain petty and cost a star on the rating. Currently, this NAS officially supports 8 24TB Synology drives. It also supports up to 32Gb of Synology RAM and either 400Gb or 800Gb Synology m.2 drives. From my reading, using non Synology branded RAM and m.2 drives will cause error warnings or non booting. This further proves Synology is likely to force their drives on us again in the future. I researched the new enclosures that utilize USB C instead of eSATA. There is no noticeable speed increase with the new bus. This is nothing but a money grab obsoleting the older expansion units. With my hardware gripes why use Synology? The reason is the disk station software. Although I know how to use Linux, it is not my favorite thing. 99.999% of the time you do not need to telnet or shell into a Synology NAS to make changes outside of what the interface allows. There is no other NAS on the market with as powerful and user friendly interface. The software has multiple applications available for backups, mail servers, virtual machines, dockers, cloud sharing, and multimedia streaming. It is easy to find 3rd party software for Synology as well. If you want a mostly hands off NAS, Synology is the brand. Once you get everything running, it just works for several years without issue. If you like to continually tinker with settings, Synology will drive you crazy with passive aggressive messages while forcing changes in terminal or power shell. Yes it works with Plex. No, it doesn't offer transcoding. Will Synology be my brand of choice in the future? It depends on how they handle 3rd party components. For now, I have another 5 years before I need to make that choice. If you have an older Synology NAS and don't want to move to another vendor, I suggest purchasing a DSxx25+ series if you like your 3rd party drives. Although it is unlikely, going to provide you with a huge performance upgrade, it will provide you with 5 more years of Synology updates and support without having to make a decision regarding 3rd party drives.

I looked into a lot of different NAS solutions, and I chose Synology because I can dynamically add to my array without losing data or reformatting. Several other manufacturers (you have to ask their tech support to find this out) require you to completely reformat the new array when you add a drive (as if I have 40+ TB just sitting around to do a backup). I also like that Synology's proprietary RAID allows me to mix different size drives and not have to live with just the smallest drive size (there are some limitations to this). I also like that I have 8 drive slots, so IF drive prices ever come down again, I can start adding more drives.

I bought this hard drive station thinking I could put in HDDs from another brand, like Toshiba NAS N300 16TB. But no, it won't let me; it says it only supports Synology drives. It also doesn't allow me to put in NVMe drives that aren't Synology, and the worst part is that the capacity and speed of the NVMe drives Synology offers are 10 years old compared to what's available today. I don't recommend this hard drive station for anyone looking for flexibility when it comes to selecting the drives they want to use. They should change the title of this product and state at the beginning that it will only work with Synology drives.

Synology devices have been my go-to devices for data storage. They're extremely reliable and although the software might not be as feature-filled as other brands, you're paying for the stable reliability of the device. I've only had one ever die, and that was after almost 10yrs of service. It was not even Synology's fault. It was a batch of faulty chips years ago that affected lots of devices. I've now purchased about 5 of these and they're all solid.

Three-time Synology owner (DS1812, DS1819, DS1825) and almost wasn't given the now short-lived decision by Synology to only support first-party drives (Synology branded) on the DS25 series. So it is clear, as of DSM 7.3 Synology has silently walked back their short-lived first-party only experiment and now third-party drives are supported on the DS25 series. There are still some first-party requirements around NVMe (be sure to read up on it, search "synology drive compatibility policies"), but third-party 3.5" spinning disks work just fine. I have a fleet of Western Digital Red Pro 18TB drives working very well in the DS1825. Comparing Synology CPU, memory, networking, etc. against Synology's competition is missing the forest for the trees. It is rather well-known (and accepted) that Synology NAS's do not have the latest, greatest, best, fastest CPU's and memory "per dollar". We buy Synology for the best software and support, not for bleeding edge bountiful hardware. DSM (the OS) and the package management is second to none for prosumers looking for something that is feature rich and "just works" without fidgeting, tinkering, and hacking around (although you can certainly do that as well). My Synology runs as a SMB share, DNS Server, and DHCP Server. It also provides the backend NVR functions for several non-Synology cameras through Surveillance Station and serves to backup my personal OneDrive (natively through Synology Cloud Sync and Hyper Backup) and iCloud Drive (through some third-party tooling given the security enabled on my iCloud account and Synology Hyper Backup). Other functions I've used over the years include the Container (Docker) manager, Active Directory integration, and using it as an iSCSI target. From a software standpoint, each of these use cases have worked very well over the years and remain the principal reason I look to Synology for my NAS needs. They just work without much care and feeding (other than software updates). I evaluated and built out a TrueNAS host (with ECC memory, LSI HBA and everything) given first-party drive requirement from Synology (I was frustrated like everyone else). TrueNAS is fine, but I just don't want to tinker anymore. After reading about Synology DSM 7.3 supporting third-party drives, quickly picked up a DS1825 and some fresh WD Red Pro's over Black Friday 2025. If Synology decides to go down the road of "first-party drives only" again on the prosumer lines (like the DS), it'll be on a future series and equally as frustrating. Fingers crossed they've learned their lesson. For now, I've got 7 years of Synology DS1825 with third-party drives to enjoy until I am in the market again when the DS1832 is released. We'll see what it looks like then.

I've owned quite a few Synology NAS units over the past 14 years—the DS1812+, DS1813+, DS1815+, DS1819+, DS1621xs+, and DS1821+. With the exception of the DS1815+ which had a design flaw that practically guaranteed premature failure, the rest have been reliable 5-star products. Unfortunately, the DS1825+ is not a 5-star model. Historically, Synology has used Delta power supplies in these units. They have always been whisper quiet. Synology chose a different power supply for the DS1825+. (I suspect it isn't sourced from Delta because the power cord is plugged in at a different orientation than all my previous Synology units.) This power supply emits what sounds like coil whine, a high-pitched noise that can be heard above everything else in my office. I found it to be very distracting. After returning my first DS1825+, I ordered a second DS1825+ from a completely different high-volume vendor. It exhibited the same high-pitched noise. I spent more than a week working with Synology Support, which was excellent (as usual). The determination was that this noise is just the way that the DS1825+ sounds. They offered to do an exchange but conceded that a third unit was likely to sound like the first two. I will not be ordering a third unit. It's worth noting that if this unit is going to be kept in a dedicated server room, then the noise doesn't matter at all. And I have no reason to think that the unit has any other issues. That said, most users are going to use it in an office. For this type of deployment, I cannot recommend it. Two stars.

Hardware is topnotch. Easy to install hard drives without tools. Nicely done. Setup software couldn't find Synology's own webpage. REALLY??? That part of the setup was clugey. However, once DSM was installed, setup went smoothly. I installed 4 Synology 16TB hdd's and the unit runs very quiet. Can barely hear it running. In contrast, my other NAS with 4 Seagate 14TB hdd's, I can hear from the other room. I would definitely buy it again and would recommend this to others.
