Compact design and attractive. i was a bit afraid to do this on my own but it was simple to put together and get working. Have not had it for long but so far no problems.
Power adapter is thin enough to fit a 2-prong cord next to it in a power strip.
Easy to install, reliable. I have 5 of these units (or their USB-3 predecessors), some of them in service for 2+ Years. Contrary to another review, none of the 5 units I have produce any noticeable sound above a low hum.
Does not rely on CPU, PC power supply, OS or any software. This is hardware RAID and does not rely on PC.
