I currently have a Drobo 5D. At the moment it holds 3 WD Red 3TB drives. This leaves me with 2 free bays for expansion. The Drobo is primarily used for video editing. All of my projects for FCPX reside on it, and I work straight off of it via ThunderBolt. To be honest the more I use it the more I feel I could replace it with a faster drive more suited to my uses? I would prefer to stick with RAID5 so I have a single disk redundancy just in case. For my uses, would I be better off with a Pegasus or a Lacie?
