Hi there!
Let me start by saying that i am just trying unRaid for the last few days and like it a lot!
I do have a question about parity calculation though. My HW is HP Microserver gen8 with G1610T CPU, two WD REDs 3 TB, two shucked HGST HE 8TB and 128GB SSD for cache.
In my PC al HDDs bench slightly below 200MBps, in unRaid while doing parity calculation with only 2x8TB connected (2x3TB are unmounted, and not associated) the speed I am seeing is 40-50MBps. Is this to be expected? CPU load is never greater than 20%, so what is the bottleneck here?
