It was very easy to set up. It was working in less than 30 minutes. I attached it to a Win 2012 Essentials server using eSata in Raid 5 mode. I am using it to replace a WHS setup.
Power adapter is thin enough to fit a 2-prong cord next to it in a power strip.
Does not rely on CPU, PC power supply, OS or any software. This is hardware RAID and does not rely on PC.
It recognized my drives, and transfers files just fine
