Why is only the LED indicator light for HDD1 on when there is data being read in the RAID 1 created by HDD1 and HDD2 on D2-310, D4-310 and D5-300C?
The date on the two hard drives is completely the same if these two HDD’s are created as RAID1. Where reading data, only HDD 1 is being read and HDD is under the waiting status, which will help to last the HDD’s life.
