Good NAS, shame about the old processor

DSM (software)
Synology..
Synology HDDs only

Great NAS. Despite the vendor lock for hard drives, I bought this NAS anyway. There's a script on GitHub to use drives from other brands. It works great, and I highly recommend it.

Nice product, but good preparation is required.

Works well
Easy to install
Installation beginning is not all plain sailing

The product works well. I did have to install it several times before the optimal configuration was complete. This was because different types and sizes of hard drives were used. That's also a plus (you can combine multiple types of hard drives).
