Synology is great. I've got a 2012 model still chugging away in my closet with no signs of stopping. I can probably count the number of times I've had to reboot it on my 2 hands. Very reliable. I just wish they would put slightly more powerful CPUs in their lineup.
But I also have a 2011 model that is still chugging away. I'd still be using it today as my main NAS except I wanted to get a second NAS to act as a physically separated, mostly cold backup. The old one is now a Hyper Backup target for the new one, and I have it on a power schedule so that it spends 99% of the time completely switched off.
I've got a 2012 two-dish model too, right now it's only used as home media server but for quite some time I was using it for work (NFS with users and all that, and iSCSI for occasional use). Setting it up was stupidly easy.
