Sounds like they are cooking or vibrating themselves to death? But also, longer term, you realize Greens are explicitly stated by WDC as not for RAID 5? And RAID 5 implies 24x7 and they're also not a 24x7 drive? The early failure isn't what you asked for, but you've got drives that aren't really applicable for your use case. > what is your experience with 3TB drives, WD and others? > > (low power drives appreciated, performance is not an issue) The WDC Reds are what (it seems) the buyers of Greens thought they were buying. Take a look at those, you can use them in RAID5 and 24x7 and they have a 3 year warranty. And for a non-enterprise disk the Hitachi Deskstar for that same size and warranty range, and I *think* it's a 24x7 drive also but I could be wrong.
