Just started data hoarding movies, thinking about hopping on this Costco deal, opinions?

I saw an ad on Facebook for a 4tb nas for 50 bucks. It's a Lacie with dual 1gb Ethernet and yeah it's a 4tb alright. Idiot selected maximum security storage and had it mirror 4tb 8 times. Also has 4 USB ports which I added another 2 4tb to. That I already had. This was 6 months ago and ive filled up all those 36tb and another 40tb. Then I have a 4tb+2tb+ the 2 SD card slots have 1tb+1tb so 8tb in my little handheld and I don't want to admit what I have in my desktop. But I got a good deal on USB C 1tb SSDs and bought more then all my fingers and toes worth. Everything is 95% or more full.

Should I get help?
