My 2012 Mini Server model with 4GB RAM and 2x1TB HDDs is arriving tomorrow and I would like to start setting it up--it is only being used as a server (files, calendar, mail, contacts, TimeMachine to external drive, VM host, etc.), so I am hoping for some suggestions before I begin. I have 16GB RAM which I will use to upgrade the server and I have a 256GB Samsung 840 SSD on hand. My debate is what to do with the SSD, if anything. --Use it externally for VMs in a USB/TB enclosure --Use it internally for a Fusion Drive --Use it internally for a Boot Drive What would be its best use for a Server? If I use the SSD externally, would you recommend upgrading both of the 1TB HDDs to 7200 RPM HDDs? If I install the SSD internally, should I leave the 5400 RPM 1TB HDD in the Mini or should I replace it with a faster 7200 RPM HDD or with a larger (2TB) 2.5" drive to compensate for lost space? I hope to only upgrade this once at the beginning and then set it up and let it be for a while, so I appreciate any feedback you all can offer.
