Review on OWC Mercury Elite Pro Dual RAID USB 3.1 / eSATA Storage Solution, 4TB by Rashid Summers

I've almost finished copying about 700GB of data for a work colleague to have a safe backup hard drive for safe use. This damn thing corrupted my drive copying the last few files. WHAT?! I cannot send such a disk to someone to use. It would be better to throw everything on flash drives. Absolutely worst experience with an OWC product I have ever had. The time I spent copying these files is annoying. Now I have to figure out the data erasure and send the damn thing back for a refund and find a new solution. What a waste of my and my colleague's time. So much for trusting OWC for a reliable experience.
