This (disk-less) 4 HD WD NAS looks EASY & cheap ($330) but it's seems to be RAID or JBOD only. Can I put 4 NON-RAID / NON-JBOD x 6TB drives in there & just duplicate 'em to my 4 bay ICY DOCK's as back-up? I just want to replace my 4 separate ~ 4 HD ICY DOCK's that use existing, small HD's & stick them in a single unit w/ big HD's. I would like to access my 4 x 6TB data from anywhere, but I really don't know where to start? Should I buy this pre-built NAS or DIY? EDIT: well - at the end of the next video, he refers to Synology & I am reading about that now... I'm not a newb & I've built my own game boxes for 20 years & I run linux on my old PC's, etc. Any advice in helping me avoid hours & hours of research is appreciated!!!
