Noticed a lot of concerns about drives not be listed on drive compatibility list. I purchased Samsung SSD drives and Ironwolf HDD drives and everything has worked as expected. One detail I wish I would have known up front before purchasing: research RAID configurations. I had to go over budget to get a 3rd 4TB SSD drive to have 7.6 TB of available space for writing new files. If you use the SHR raid type the 2nd drive installed in a volume will be set aside for backups. Otherwise, loving the intuitive DSM user interface and plenty of good YouTube videos to help do it yourself first-time NAS owners like myself. This has been a perfect fit for video editing in 4k and being used as a central databased for CAD-based software like Revit once I upgraded to to the 10 GbE connection.

I've never owned a Synology NAS at all before. I've been getting in to more homelab type stuff lately and it was getting to the point where a couple of Raspberry Pis weren't really cutting it anymore. I wanted to get something that's compact, relatively low electricity use, has lots of storage, and can run VMs and docker containers. This thing fit the bill perfectly.I'm a linux engineer and programmer by trade. I can honestly say that the DSM web interface is the absolute best web interface I've ever seen anywhere. It's absolutely incredible. It feels like you're using a desktop operating system in your browser and everything just works, I haven't run in to any problems with it at all. Synology have done an excellent job of making the UI friendly enough for average users to be able to use it, but also flexible enough for power users to get what they want to done. The ability to SSH in to the NAS and issue commands directly is great too.Things I've been able to do with mine so far:- I installed the docker package from Package Center and setup several docker containers (heimdall, pihole, jellyfin, uptime-kuma, etc...) and mapped their data directories to be stored under sub-directories of the docker shared folder which gets automatically created when you install the docker package. I then created another shared folder called docker_backups. I then navigate to Control Panel - Task Scheduler and created a new task for each of the containers to back them up to that location every 3 days. An example of one of the commands that I used to do that: docker stop pihole && tar -cvzf /volume1/docker/backups/pihole.tgz /volume1/docker/pihole; docker start pihole- I also installed the Virtual Machine Manager package from Package Center. I then took a backup from my existing Home Assistant server that was running on a Raspberry Pi 3. I downloaded the .ova for Home Assistant OS from the Home Assistant site and imported it in to the Virtual Machine Manager which worked flawlessly. Then once the Home Assistant VM was booted I restored by Home Assistant backup to it. I plugged my Z-Wave controller in to the USB port of the NAS. It showed up a few seconds later and I mapped it to the VM in Virtual Machine Manager. It has remained mapped ever since, the mapping has survived several reboots of the NAS. After that I went to Task Scheduler and created a new task to backup the VM weekly with the following command (note that I found that the VM's name needs to not have any spaces in it for this backup method to work, so first I renamed my vm from "Home Assistant" to "Home_Assistant"): /var/packages/Virtualization/target/bin/vmm_backup_ova --dst=vm_backups --batch=1 --guests="Home_Assistant"- I created several shared folders for documents, backups, etc... and I used the Synology Cloud Sync package to automatically send the most important files up to my Google Drive. Synology Cloud made setting this up super easy and the synchronization is virtually instantaneous when there are changes or new files. This is an absolutely killer feature that I love. If I were doing this on a regular Linux box I'd likely need to mess around with some third party package trying to get something like this to work, and it likely wouldn't be anywhere near as good as this is.- I wanted a second IP on one of the interfaces but I found that there's no option to do that in the DSM interface, so I found a simple but kind of hacky workaround of just creating a new task in Task Scheduler to run this command every minute (they didn't have an option in there to run on reboot): ifconfig ovs_eth1:0 10.0.0.8 netmask 255.255.255.0 broadcast 10.0.0.255 up- I installed the Snapshot Replication package from Package Center and I set it up to do btrfs snapshotting on several of the shared folders which I consider to have data that we want protected from things like accidental deletion and ransomware. The snapshotting keeps track of only the changes which are made to the files in the folder each time a snapshot is taken. This allows you to navigate through a snapshot folder and go back to a specific date and see the files and folders as they were on that date. So for instance if ransomware were to encrypt all of your files on a share you could just go back to the snapshot from the day before and get all of your files back. I have it setup to keep the last 128 days of snapshots for each folder. This is an absolutely killer feature which is one of my favorite things about the NAS. If you have a shared folder mapped as a network drive on your windows computer you're also able to navigate through the snapshots directly from there as well, making this even more convenient.- I installed the Synology Drive package from Package Center and my wife and I are currently using that to view our documents that we have stored on the NAS (as we currently have a project to digitize as much of our filing cabinet as possible). The NAS also has a nice "Universal Search" package which allows you to tell it to index documents in a shared folder based on the text inside of them and then perform searches based on that, which makes locating documents much easier. We just need to make sure that we scan documents with OCR enabled and then the automated indexing takes care of the rest once the documents are uploaded to the NAS which is really cool.- I setup QuickConnect which is a feature that allows you to securely access your NAS via two factor authentication remotely without needing to have any ports open on your router. I'm really liking this feature because I keep all of the ports on my router closed and this allows me to pick some obscure URL that no one is likely to guess and then to use two factor auth on top of that which makes it quite secure.- I installed the Antivirus Essential package from Package Center and set it up to perform periodic scans on the shared folders. It's nice because it can detect whether or not a file has changed since it last scanned it, so it only scans stuff that has changed which makes the scan times significantly shorter after the initial scan.- I installed the Document Viewer and Synology Office packages. The Document Viewer allows you to view documents from the DSM interface and the Synology Office package allows you to create new word documents or spreadsheets from the Synology Drive interface which is a really nice feature to have.- I installed the Synology Photos package on the NAS and on my phone and configured it to automatically backup the photos from my phone to the NAS. I also installed other packages on my phone such as Synology Secure Signin (used for two factor auth), DS finder (used for managing the NAS from your phone), DS note (used for keeping notes, kind of a high end notepad which is also accessible from the NAS itself), DS file (allows you to browse folders on the NAS from your phone), Synology Drive (Allows access to the Synology Drive interface from your phone), DS get (allows you to tell the NAS to download a file).- I also configured a feature called Active Insight which is free for up to 3 Synology NAS devices. It collects monitoring and event info from the NAS in to the cloud and allows you to access it any time from a browser or from the Active Insight app on your phone. It stores the historical data for up to 6 months. I tend to do most of my monitoring locally but it's nice to have a backup monitoring method like this just in case.- I also configured email notifications on the NAS so that it notifies me if there are problems.As you can see between the docker containers, the VMs, and the myriad of other features which are available this thing is a little powerhouse that can do just about anything you'd want to. I'd estimate that you can comfortably run around 4 or 5 VMs on this and probably like 30 docker containers before you really start to max it out (depending of course on what those VMs and containers are doing). If it's something overly intensive then you might max things out with just one docker container, it's really up to you to manage the resources appropriately, but this thing is no slouch when it comes to processor capabilities.I highly recommend upgrading the RAM to 32GB if you plan to do docker containers and VMs. Also most unused memory will be automatically used as a disk cache which will help with overall performance as well. I recommend installing a couple of NVMe Gen3 M.2 2280 SSDs in it to use as disk cache. I'd recommend only using them as read-only cache as read-write cache can cause total data loss if a cache drive fails. Even when using them as read-only cache I'd recommend using them in a RAID 1 configuration just in case one of the cache drives dies so that you have time to gracefully shutdown the NAS and replace it. I'd recommend only using about 75% of the space of each NVME drive to leave blocks free to be used automatically as other blocks are exhausted, this will extend the life of the drive considerably. Do not buy Synology RAM or NVME drives, they are horribly overpriced. For NVME cache drives I'd recommend SK hynix Gold P31 and for RAM I'd recommend 32GB (2X16GB) DDR4-2666 PC4-21300 ECC SODIMM Compatible with Synology D4ECSO-2666-16G Memory Upgrade Module by NEMIX RAM. Much cheaper and works just as well. If you need a second 10gig port on the NAS then I'd recommend getting the Synology branded pci-e 10gig card for that, it's overpriced but it'll ensure that you're not dealing with driver issues like I've seen people report with other cards.

I previously skipped this for the 1821+ because when this launched Synology was very aggressive at pushing their own re-labled drives to the point that they'd degrade the interface instead of popping up a hey we didn't test these drives message like all my units before including the 1821+. The non-approved drives are still marked yellow but not red anymore and they don't block stats on your drives that they do show on their own. The rest of why one would buy Synology over competitors or building your own system is still there, their OS DSM and the integration with the hardware.I did upgrade the ECC RAM and added a dual 10 gigabit intel network card and working across this many spindles (or now SSDs in my case) with the new SMB3 feature allows 20 gigabit throughput so I can live edit my files (4K video) while my family does tasks like streaming our video library or working on documents and photos, while a few VMs and docker containers churn away in the background like home assistant and a DNS server.There are unapproved ways to get the yellow lights to turn off if using a drive not on the list that hasn't been tested as incompatible if you know what you're doing an the yellow status is annoying, this isn't needed if you're going to set it up and only bother it when getting an email about time to change a failing drive. Don't use this workaround if buying this for your business buy their drives for the added piece of mind, their drives just aren't what I needed as a home enthusiast especially for what they charge.Yes you can wholesale migrate from another unit if you follow their requirements for migrations by moving drives from one unit to another, I did it from a 718+ to the 1821+ to this 2422+ with the only complaint from the last two units being about my choice of drives, which were just fine on the 718+ as they were listed and tested there.

This is an excellent NAS. It runs really well and is much faster than my 8 year old Synology NAS. It does everything I ask.I can transfer gigabytes to this very quickly.I have to say after years and many tech support requests Synology really supports its products. They answer every question and will be there for you for tough issues. This is a product well worth your consideration.Concern over noise. You can set the fan level from full (loud) to quiet or to cool. I have a cache configured and that nearly shuts off the fans. I hardly hear that NAS. Not an issue.There is a learning curve with this as expected. You need to configure it to your liking and use cases. Please consider not all reviewers took the time to optimize this to their needs.With the prior device I was able to use Synology software to back up and restore all my data. I transferred all my data to this using their Hyperdrive backup. It worked without a hitch. Data was secure.Serious buyers should read the online reviews and the youtube videos about choosing a Synology NAS. This will get you an idea of what you are getting with this device. I recommend it and also recommend choosing your RAID level of your volume created very carefully so you don't have to rebuild this later.

Replaced my 10 year old synology with this one. Works great.. 10gps Ethernet is future proof. Runs docker like a champ. I have a half dozen containers running and rarely see the cpu over 5%. Does not support hybrid raid if you want a model that supports a mix of drive sizes or hardware video decoding look elsewhere in the lineup.
