I just traded a Synology 413 for a Drobo 5D.
The Drobo is significantly faster at data transfers. It also spins up from sleep much faster and spins up with my Mac (I had to manually wake up the Synology). The cooling fans are a fair bit louder on the Drobo (that being said, Drobo packs the drives in tighter than Synology so that might not be a bad thing). I also like being able to dim the Drobo lights since it is in my bedroom.
Do note that the USB 3 interface for the Synology is only for attaching external storage. Unlike the Drobo, you cannot directly connect the Synology to the Mac via USB 3 (only over Ethernet).
Drobo seems to polarise people's opinions so much. It seems to have this reputation for not being considered a serious but of kit.
The only thing that I don't like is the non standard RAID implementation. I'd feel better if I had the choice to choose what RAID set up I wanted. The dashboard software is limiting much more then I was expecting but then I was running a Qnap NAS which has a ton of options.
