In my case, Synology has worked fine. Reliability is a big deal for non-backup RAID (not the same as "backup," but does the trick, 90% of the time).
It's entirely possible that their newer units are crappier than the old workhorses I have.
I don't use any of the fancier features that might require a beefier CPU. One of the units runs a surveillance station, and your choices for generic surveillance DVRs is fairly limited. Synology isn't perfect, but it works quite well, and isn't expensive. I have half a dozen types of cameras (I used to write ONVIF stuff). The Surveillance Station runs them all.
