Adding 2nd HDD to the already new SSD for our mid 2011 Mac Mini

My Problem

No problems but, we replaced our old WD externel drive that started to get noisy with a new Synology TS-251 2-bay NAS external unit and a Seagate 4TB IronWolf NAS SATA 6Gb/s NCQ 64MB Cache 3.5-Inch Internal Hard Drive and thus wanted to have the old Mac Mini updated as well and installed a new Samsung 850 EVO 500GB 2.5-Inch SATA III and will pair with an old 500Gb Seagate HDD using raid1.

My Fix

Replacement of the MacMini HDD with the SSD went very well and is up and running wit our new Synology system.

My Advice

If you don't really need to replace your external drive you should wait for SSD prices to fall; they probably will within the near future due to technology and competition.
