I'm looking at consolidation of a few servers data onto a NAS device, we have had a few office closures and the server warranties have run out so it makes sense to put it all on a NAS.

I have only ever seen Qnap in use and it seemed pretty good, but I've been looking into the Synology RS411 8TB rackmount, their support has got good reviews which is essential for us.

We have about 2TB of data to store and I wanted to set up a RAID 10 on a minimum 8TB system giving me 4TB of space which should cover us for a few years

I just wanted opinions and preferences on brand or info on better pieces of kit.
