I’m trying to set up a RAID6 md array on fedora22 using four WD30EFRX-68EUZN0 disks and would like to make sure I’ve tuned the disks for best performance and lifetime.
I’m interested in any tips for tuning these drives. I was reading the thread located here regarding the idle3 timer:
It seems to indicate the idle3 timer should be tuned to a 300s value to decrease the number of times the head is parked, considering the drive will be used in a NAS setting and infrequently idle.
It looks like it’s now possible to disable the timer completely, and wondered if people thought that was a better option?
Do you have any other tuning or performance tips I should know about for this drive running on Linux?
