NAS newbie friendly
I recently purchased this system to make my own "cloud" and remove the need to save all our family photos on Amazon's prime subscription photo storage service. Prior to this I had never has a NAS and knew nothing about it. Once the system and Seagate Ironwolf NAS drive arrived, I put it all together, go it plugged in and within 20 minutes it was up and running. Synology has their own host of mobile apps that you can download for free that act in the same way Amazon's photo service does and automatically saves your photos to the NAS and even organizes them by date and time the picture was taken. I'm also able to store and share documents from the NAS much faster then trying to email everything or using a USB drive.Overall, I am very happy with the system and its compact design. It fit perfectly in a well ventilated cabinet next to my printer.

I just put two iron wolf 4tb in as raid mode 1 and my photos are now safely backed up and available locally. But then I installed python, enabled ssh, installed web tools and ran my own web server! Everything works so well. Of course I shut down the web server because I don't need one, but still I am impressed at how well it performed. As a NAS it just works, I have access to my network drives without issue. I love the dsm interface, it's so easy.

I finally just replaced a 2013 mac mini server which had been backing up to a 2013 Apple Time Capsule. I obviously needed to upgrade my external storage and wanted to go the NAS and RAID 1 route, but with easy set up and without unneeded complexity. I quickly and easily installed 2 Seagate 6TB IronWolf Pro 7200 rpm SATA III 3.5" Internal NAS HDD and then within 90 minutes of turning this on, my new iMac was sending its initial Time Machine back up here. Synology instructions are simple and accurate. I was also able to quickly connect my iPhone and new iPad Air to this NAS. Now my old mac mini server just completed one last Time Machine back up to this NAS, before I take her down. This Synology DS220j is extremely quiet and even looks good. Highest possible recommendation.

I finally just replaced a 2013 mac mini server which had been backing up to a 2013 Apple Time Capsule. I obviously needed to upgrade my external storage and wanted to go the NAS and RAID 1 route, but with easy set up and without unneeded complexity. I quickly and easily installed 2 Seagate 6TB IronWolf Pro 7200 rpm SATA III 3.5" Internal NAS HDD and then within 90 minutes of turning this on, my new iMac was sending its initial Time Machine back up here. Synology instructions are simple and accurate. I was also able to quickly connect my iPhone and new iPad Air to this NAS. Now my old mac mini server just completed one last Time Machine back up to this NAS, before I take her down. This Synology DS220j is extremely quiet and even looks good. Highest possible recommendation.

4.0 out of 5 stars Easy to set up, easy to integrate with AD, lots of features but a few shortcomings

There's no reason to consider using the Synology cloud for photos and files - this drive has neither the compute nor the throughput to make use of the (rather excellent) Synology Photos. Indexing 20GB of photos would take MONTHS when a comparable cloud service or self-hosted solution could do it in hours.

But it is a TERRIFIC backup, archive and long-term storage drive. I use it for desktop backup and for archiving containers and virtual machines. It's a great Plex server, find the setup instructions on the Synology site. It integrates with Active Directory so you don't have to configure another directory with passwords for everyone to forget. Synology Desktop Backup is a fantastic solution for smaller workgroups (12 users)

Synology Drive: Useless. The performance just isn't there for syncing on endpoints. Synology Photos: Useless. It brings everything else to a crawl and your index will never complete. Containers: Won't run on the DS series.

There are other faster, more expensive solutions for photo and personal cloud storage. But the DS220j is a really good "data glacier". The UI is very intuitive (it's a lightweight Linux of course). Gigabit networking will transfer large files as fast as both ends will allow. Load it up with some reliable enterprise-grade drives (I used Exos, they've been going strong for 4 years now) and enjoy data hoarding.

I first purchased a Terramaster F2-212 and within the first 2 weeks I had 3 issues. After the third issue I returned the unit and purchased this unit from Synology. I've had this unit for 1.5 months now and not a single issue. The system is flawless and the user interface is great. I couldn't grade the tech support because I never needed them.

5.0 out of 5 stars Super easy and way easier than DIY

I had a DIY NAS on a Raspberry Pi for a while. It was extremely slow, despite multiple optimization efforts. So slow it was barely usable. Eventually I asked around for some advice and got Synology mentioned. I am so happy I got this. It was extremely easy to set up and performance is great so far. It is very flexible in terms of how you set it up; for example my drives don't quality for RAID but I can still do automated backups from one drive to another every day. Even if you know nothing about RAID (which I don't) I would recommend this if you want to have a drive accessible from multiple computers / locations or want to have control over backups.

1.0 out of 5 stars Can't recommend what never worked

We ordered one of these after our Asustor NAS died. It arrived and was set up per instructions, and never connected to the router. No IP could be found. In fact, no connection to it was ever established. Assuming it was a flaw in manufacturing, it was returned for a replacement. The replacement arrived and did the EXACT SAME THING.

The error code indicated that it having no operating system was one of the reasons why it wasn't working. The other two potential reasons were no disks installed (Identical, unformatted disks were installed per the usual routine for NAS's) or that it had a "loss of configuration" status.

You can't really lose what you never had, so I'm assuming it was no OS.

BOTH DRIVES were returned, and a refund should be issued.

AMAZON did a GREAT job getting the replacement to us, so no issues there. It's that they shipped it in a plastic bag. Typically electronics do NOT do well in plastic bags, so my guess (supported only by the possibility that this is what happened) is that the METHOD of shipping was such that a static charge could build up on the bag, and cause sufficient EM interference to detrimentally impact the memory.

The NAS is mostly built out of plastic, too, which while an insulator, does nothing to stop EM radiation from passing right through it. Metal would have been better, but there wasn't enough metal in it to provide sufficient shielding.

Again, that's a guess, because I can't for the life of me imagine that something like a consumer-level NAS as this is would ship without a functioning OS installed. I've set up probably half a dozen of these kinds of devices in the past, I know what is needed to ground things, and do practice good electronics hygiene when working on these. So it wasn't anything I did. It was the device (BOTH of them).

I can't recommend what never worked. Two for two DOA (or at least with a blinking status light saying it wasn't going to work) gives it a one star, and it didn't even deserve that much praise.

Your mileage may vary, but if it arrives in a plastic bag, I'd be concerned.

The Synology DS223J NAS impresses with its swift performance and user-friendly interface. Its dual-core processor and intuitive DiskStation Manager software ensure smooth operation for tasks like multimedia streaming and remote access. The sleek design, multiple connectivity options, and built-in applications add to its appeal. While expandability options could be more robust, the DS223J remains a top choice for home and small office environments, offering excellent value and reliability.
