Windows Storage Server 2012 Workgroup edn - users?
I'm looking at NAS solution to backup our Windows Server 2012 R2 to. One of them (Buffalo) uses Windows Storage Server 2012 Workgroup edition, which says it's limited to 50 users which I'm a little confused by. We have 150 users on out main server, but if I am using the the NAS to backup does this matter (as it'd be one 'user' connecting to the NAS)?
If it does, can anyone recommend a NAS box that will work with Windows Server 2012 R2 with a 2x2TB storage?
