The Synology DS was purchased to replace an old server that had quit. I was able to protect the data and get the unit up and running easily.

This is a go-to device to setup on-site backup of workstations and servers via the Active Backup for Business. Then we connect Hyper Backup to an S3 storage provider for online backup that is cheap and efficient.

I use the 1520+ for media storage including photo and video backups, Mac and Windows backups including for Time Machine and a windows based separate solution. I also use the synology backup solution for a Linux server. I’m running several docker containers and have had nothing but excellent results. I bought it in a bundle with 14TB drives and despite some concerns about possible drive compatibility there has been no I’ll effects. I added NVMe cache storage but for my use cases that doesn’t really do much for me. I’ve been impressed with the versatility over all and the power to run docker containers is pretty impressive. It works very, very well.

This is the best personal use/light business NAS for your dollar that you can buy today. Synology makes a fantastic products that are easy to use and configure and compatible with any of the mainstream software makers that you may deploy on it. This NAS SPECIFICALLY has advantages over even the updated versions that Synology has made. Things like cache storage capacity, default RAM amount, processor speed and process handling. Very easy to use and clean looking GUI and a surprisingly low profile in case you have it on your desktop. Not sure what your need for a NAS may be but if you want one to run a Plex/Media server I can assure you this will be all you will every need for a long time. This will take care of many and most of your home entertainment media. With a proper setup using Docker and container builds for your programs that monitor your shows, music and movies, this NAS will operate flawlessly and allow you to go almost completely hands off when it comes to obtaining, sorting and displaying your media. Some of you may find the drive bay locking feature helpful if you have curious children or you are in an environment where a little bit of added physical security is needed. The front USB port makes transferring media that you already possess a lot faster than using the browser transfer method. You will be pleased at the rubber supports that curtail the unit from sliding and furthermore since not everyone can afford fast, large capacity HDD’s all at once to fill the 5 bays, this NAS is able to be upgraded to accept another array of drives via an supplemental external bay. That way you could improve the quality of your drives on a time frame that better suits you and transfer/swap the data later. Lastly don’t be fooled by the mimicked version of this NAS that has the AMD processor in it. It’s trash and not compatible with some of the software architecture and processing threads needed to run a successful and problem free NAS media server.

We had a DS1515+ that had the power supply die in it, so bought this one in hopes that we could recover. Put in the drives from the old unit, powered it on, ran through a quick migration wizard, updated a couple apps, and we were back in business.

What can I say? Upgrading from my DS1515+ that I had for more years than I can remember was as smooth as silk. I moved the drive into this device and it walked me through a migration that took only a few minutes. As far as the device itself: It’s speedy, does a great job serving as my photo and file storage device in my home, and, most importantly, the media server that all TVs in my house are hooked up to via Plex. I held off on the newer, AMD-based version, because folks mentioned that the Ryzen CPU had issues with Plex and transcoding.

Haven’t had the system up and running too long, but is working as expected. Populated with 5 WD Red Plus 10t drives. Set up and initialization went very smooth. Best advice, go to Synology and read all documentation/User Guide, it will make your life easier if you are not used to setting up a NAS.
