*Apology for my poor English and poor knowledge about unraid system. Hi guys, files i'm dealing with are mostly normal sized, but i do collect HD movies and my work produces lots small sized pictures. So my questions: 1. How much space do i have to give up for redundency? If i have 6x 8t drives, do i still need only 1 parity drive( let's say 10t ) to keep all my data safe? 2. What are the average speeds of copying large files and pictures. (My Qnap is doing 120mb/s on large files, but pics (large amount) are just painfully slow somtimes 10mb/s sometimes 500kb/s). If i use some good HW, maxed up my ram will copying be faster? 3. Can i run Roon server with unraid. Thanks in advance.
