You are right - it's not illegal for people to copy their Blu -rays and share in many countries with friends and family .what are you talking about illegal? you know that all the content is legally obtained by ripping owned UHD and BD discs!
Looking at this, all I can say is the dang thing is over priced and under performs. We can get quad M2 PCIe x16 adapters for less money that split four lanes to each M2 and they don't require any kind of chip on them. The other problem is, there are no 8TB M2 drives available as yet, AFAIK that claim is bogus. The highest capacity I've seen available are 4TB units. There may be an 8TB in the future but they're simply not available (Unotanium) at this time.
