Yes, the type of data use that the user goes through will have an impact on storage choices. My 2014 Mac Mini has the oem 500GB ssd and it's primary job is for system files, application software and documents. On a gigabit network, I have a 2x2TB Synology NAS in mirror mode that I use exclusively as my Time Machine target and a Pentium 4 tower running OMV NAS with 4x1TB (Raid 10) for my iTunes and Photo libraries. I use USB 2.0 and 3.0 hdd and USB sticks to physically move data files when necessary. Latency when opening iTunes is not really an issue, but can be with the Photo library, however we're talking about a few seconds delay and since we have the Apple and Windows PC's it's great to be able to access those files from the NAS.
