So far I have been considering a Drobo 5D3 (I know the horror stories some people have had with Drobo's "bricking" , but I haven't had any of those problems and am currently using a 5 year old 5D and I am not getting the speed I'd like even though i have 128gb MSATA in the cache bay and 7200rpm drives.) I like that like the 5D I can set up the 5D3 with dual drive redundancy (Drobo's version of RAID 6) and swap out smaller capacity driives for larger ones as the need arises. I have also looked at the Areca 8050U3-6 , a 6 bay Thunderbolt 3 box which is a hardware RAID solution. This being a hardware RAID I have been advised that all of the drives have to match. On the plus side ARECA appears to be very heavy enterprise level equipment and is well respected. At Lloyd Chambers recommendation I am now also looking at the OWC ThunderBay 6, Also a six bay box which uses SoftRaid as a RAID controller and can set it up for RAID 6. The drives I will be using are 10TB HGST He10. Question (finally!): Has anyone here used the earlier OWC ThunderBay boxes and what were your experiences?
