So Far - Excellent!

Bought this to upgrade and expand from a 12 year old Synology that's been running fine (with a few expected drive replacements). So far, LOVE this thing! If you're not an expert on the ins and outs of good NAS configuration I recommend checking out some great content providers on YouTube to learn the best methods to set it up right. Once it is setup, this thing works great! There are cheaper solutions, and doing it DIY could make for a little more horsepower - BUT if you want solid, simple, and secure... I don't think you can go wrong with this device.

Easy to use and the right size for our family

Synology has good software and the NAS is easy to use. I use it for personal data, and really like the peace of mind knowing things are backed up. The drive bays weren't quite as nice as an older 1515 I own, but it's still definitely worth the purchase. Five days gives a lot of flexibility and you can always expand later.

Replacing an older model

I've used Synology for local backup of photos since 2012. When my 10-year-old model finally died, Synologys top tier support ran me through some steps to confirm that it was in fact dead, and helped me easily migrate my still good drives to a new device. It was back up and running in 30 minutes. They even recommended some DIY steps to potentially salvage my old model. My 2012 box gets less use, but it's still going strong when needed.

Great for storage needs

Works great as a nas, but for hosting media servers I would advise against it because it lacks a gpu (the older version had one) and has a weak cpu. However, if the goal is mainly for storage and backups, I did not notice any issues with the hardware.

Powerful but rattles - not for a quiet space

Expensive device with the premiere proprietary forms of RAID which allows for trouble-free expansion. 4/5 stars because the metal chassis makes the device rattle when drives are spinning up sometimes.

Great new NAS, Drobo 5N replacement

I bought this to replace an old Drobo 5N. Other sounds form the HDDs, the new NAS is virtually silent; the Drobo fans were very loud. It is providing all the functionality of the old NAS and more. Setup was simple and straight forward. There is a lot of performance and control options. Very happy with the new hardward.

Synology DS1522+ is the best NAS for most people

I did a lot of research shopping for my NAS. I was hesitant about buying from Synology because the company has some really lame anti consumer business practices. Ultimately though I wanted a device that "just works". In this area Synology fit the bill and seemed far ahead of their competitors. I'm very happy with the quality of the device and the ease of setup. The software is really excellent. SHR offers a lot of flexibility for expansion. They have elegant solutions for pretty much everything you'd want to use a device like this for. I'm using this as my own "cloud" to store all my data, run Plex, and manage a large photo library for myself and my family. I'm very happy with this device overall and would recommend it to anyone looking for their first NAS.

Very reliable and support is top notch

This is my second Synology product. They are very reliable. I had a question on this unit and Synology support is top notch. They respond within 24 hours and will leave the ticket open until your issue is resolved to your satisfaction. They can be used a a Security Camera server and much more besides just backup.
