I have a WD MyCloud Ex2 Ultra running Raid 1 with 2 6TB WD RED Pro drives. Drive 1 failed today and is rebuilding just fine. I’ve done this before, all good there. I wanted to know if I can upgrade to larger drives and what the max is for this model? Also, this is the 2nd WD RED Pro that has failed in a year, so I’m wondering if I should look at another WD drive. I see they have Gold Enterprise but it doesn’t seem rated for Heavy Duty use. In my solution of RAID with 6TB of space available, I’m about 1/2 full now, so still lots of breathing room, but since I’ve got to restock my ‘backup’ drives I keep in the closet, wondered if I should think about bigger overall.
Also, this unit runs pretty hot and while the HDD’s are ‘within range’ they are a lot hotter than the PR2100 I have with runs the drives at about 40c. The EX2 is running them between 46 and 49c.
Can anyone recommend an external cooling fan I can put on top of this unit to keep them a little cooler?
