Unraid OS 6.11.5
I didn't think about this issue when I set up my array.
I have UniFi Video writing to drive 1 (so also to the parity disk)
UniFi Video is writing 24/7 to the array, thus hammering 2 disks.
Sooner or later, the disks are going to reach their max writes and fail.
One possibility: Move disk 1 to an unassigned device, thus saving the parity disk, but loosing disk protection. That disk is a WD Purple, so is designed for 24/7 operation.
Any advice please??
