Synology DiskStation is being used for multiple purposes across multiple organizations. The primary use is as a generic file server, but it is also being used as an all-in-one photo management solution (utilizing Synology's PhotoStation or Synology Photos in the latest version of DiskStation), a VPN server (either L2TP or OpenVPN), and an Active Directory Server. It is also used to host virtual machines to handle functions that the DiskStation can't handle natively (such as running a QuickBooks database, Ubiquiti UniFi Controller, etc.)
  • Synology's DiskStation Manager (DSM) provides a robust RAID experience with multiple RAID types available, including Synology's own RAID implementation (Synology Hybrid RAID - SHR)
  • DSM includes a full-blown app ecosystem to extend its functionality beyond its built-in features.
  • Synology is constantly updating DSM with not only performance, bug and security fixes but with major changes as well. In fact, the newest version of DSM, DSM 7, was just recently released.
  • The same version of DSM comes with all of Synology NAS products, from simple single drive models all the way up to enterprise-grade models with upwards of 20 drive bays.
  • DSM is not just a simple firmware OS, it is a full-blown Linux OS with all the features and benefits (and pitfalls) that entails.
  • The default file system for DSM is BTRFS. BTRFS provides some advanced functionality (such as snapshots, bit rot protection and compression) over Linux's default ext4 filesystem.
Cons
  • While BTRFS is a more advanced file system than ext4, it also is in a perpetual state of development, with many features not fully functional and a plethora of bugs. Synology has managed to overcome many of these limitations by placing BTRFS on top of a LVM, but there are much better file systems that Synology could have used, such as OpenZFS.
  • DSM's built-in backup software, HyperBackup, while robust, oftentimes runs into issues. Specifically, backups can be working fine for months or years, and then suddenly the backups will fail. Sometimes these failures can be resolved, but oftentimes the backups need to be completely restarted. Fortunately, even when the backup fails, the existing backups are still accessible, it is just that new backups can not be performed.
  • The underlying Linux OS provides significant benefits, but also adds a fair amount of complexity. Most of that complexity is wonderfully hidden by the DSM interface, but when certain problems arise, delving into the Linux command line is not out of the question.
  • Perhaps the biggest issue with Synology DiskStation is Synology's support. The issue isn't that the support is bad, but it can be frustratingly slow when dealing with a major issue. Synology does have a very active community that is always willing to help, but nothing beats first-party support.
Synology DiskStation is extremely versatile and scalable and is thus useful in a plethora of scenarios - from a simple home NAS solution to an enterprise-level setup. There are two main scenarios in which Synology IS not well suited:
1.) when a person needs a simple plug and play setup for basic NAS system and
2.) when an organization needs more than a NAS setup, but a full-blown SAN setup.
In virtually all other scenarios, Synology is a perfect fit.

Synology DiskStation a Versatile Solution That Provides Excellent ROI!

We utilized Synology DiskStation as NAS to replace the Windows file server on our smaller sites. It has helped us reduce the need to set up a server for smaller offices. We were also able to utilize the built-in and free backup solution Hyperbackup to backup to the cloud (either AWS or Azure) and reduced the need to purchase a backup solution, tapes, and the need for an offsite tape repository for data air gaping. We have also used it as a SAN on or DEV/QA VMWare cluster as well as a medium office. It provided us with a cost-effective solution for medium-sized offices that did not require enterprise-level SAN solutions using iSCSI. Finally, we had used it as a backup server replacing our previous tape drive solution. Using the Synology Diskstation has allowed us to forgo having to purchase tapes and offsite storage facilities for them. We use Synology's Active Backup for Business to backup the data. As an added bonus, backups are deduped allowing more backup frequency. Furthermore using Hyperbackup to send the data to either AWS or Azure provides us an offsite data repository for our backups.
  • Synology's NAS feature provides cost-effective and flexible file server solutions. The ability to expand the array dynamically is a great feature. It helps reduce the footprint needed when setting up a small office.
  • The Hyperback utility is a flexible and powerful backup solution. It can backup the NAS shares as well as other components of the DiskStation. It provides the option to replicate the data to another Synology as well as to the cloud. It is compatible with AWS, Azure, GCP, etc.
  • Active Backup for Business is another great backup solution that is available on Synology. It can be used to back up a physical server, VMWare virtual machines, SMB shares, etc. It can do deduplication, reducing the required storage for backups and allowing for more iterations.
Cons
  • A more robust search feature in Filestation. It is sometimes difficult to search for files in the DiskStation.
  • Improvement on the clustered NAS setup. We've had headaches after setting up a NAS cluster. Once in a while, it goes haywire and we have to figure out if there is any data loss.
  • Better support process now that they are delving into more enterprise solutions. Having the ability to call support instead of e-mails would be great especially on critical issues.
  • Expand dual controller options for the DiskStation.
The Synology DiskStation is well suited as a NAS solution, easy enough to mirror a Windows file server shares setup. Access to the Hyperbackup utility eliminates the need to purchase a tape backup solution. A portable USB drive can be used as the initial backup target. For air gap purposes can connect Hyperbackup to the various cloud providers such as AWS, Azure, GCP to copy backup data there. Utilizing it as a backup solution has also been great, instead of purchasing a tape solution, tapes and an offsite tape repository. Active Backup for Business is another excellent backup utility for physical servers, VMWare virtual machines, etc. Restoring files is fairly intuitive. Until Synology introduced the dual controller setup, using it as a SAN was less appropriate as there was occasional downtime when the controller had an issue but this was less important for the scenarios we were using it for. It would be more of a concern if we had used it for things that require more robust uptime requirements. Overall we are happy with the features of the Synology DiskStation.

We use this as NAS to store off-site backups in a data centre. All we need for this purpose is straightforward network storage and it carries out this function perfectly with very little maintenance needed.The built-in functionality which comes as standard give some useful features and, in the past, I have used a variety of these tools from Surveillance Station to the built-in web server.
  • Out-of-the-box RAID configuration.
  • Loads of built-in applications.
  • Security - lots of features that can be enabled including MFA.
Cons
  • It would be nice to see a slightly better hardware spec for RAM and processor. Using the web interface can be slow sometimes.
  • We occasional get issues with iSCSI connections after firmware update. Not a huge issue as we know to check but would be nice if resolved.
We use this as an offsite (second datacentre) storage for backups. We have Veeam Backup and Replication running in DC1 which then does a copy job over to DC2 and onto the Synology NAS. It works great connected via iSCSI to a repository server connected to Veeam.

Smart move which continues to pay dividends

We have two Synology DiskStations. One we use in our production environment as network file storage for all of our users as well as a general file share. The other we use as offsite backup. We take our Virtual Servers VHDs and back them up there. Using Rsync we also backup our on-prem Synology.
  • Software interface is not overwhelming and relatively easy to use.
  • Reliable. Never have any issues with it.
  • Pricing. Much less expensive than other options we looked at.
Cons
  • It's different than a Microsoft solution - things laid out differently.
  • Meets our needs so hard to identify examples of improvement.
It does not replace a SAN, but for light to general usage, it has worked great for us. The web interface works well. I like it so much that I bought a smaller version to use in my home.

We currently have multiple Synology DiskStation's in our environment and have been very happy with them. They are used for general backup with Veeam, Self-hosted IP Camera solutions and general former employee data storage. These devices have become very critical to our day-to-day activities. Both companies I work for have multiple and serve different functions as described above.
  • Data Redundancy
  • Easy WebUI
  • Connectivity
  • Scalability
  • Versatility to use different drives of different sizes
Cons
  • More Apps
  • Better warranty
  • redundant power supply options
  • more hardware upgrade paths
While I have Synology DiskStations at work, I also have one at home. While I got one of the doomed models that had multiple issues, I was able to get it resolved by a third party. My point is that they refuse to service equipment even at a cost. Thier answer is to just buy new. While they can guarantee newer hardware, some hardware doesn't need to be fully replaced and could just use a refresh. These units are NOT cheap by any means, but having more support, would be a great help. Other than that, these units are very good/robust and have saved my rear more than once.
