I've had interesting cases where WD Green Drives (specifically WD15EARS,
WD15EADS) don't necessarily "fail" but suddenly have very slow
random/read write performance which slows down the rest of the array.
Removing the drive, and replacing it with a (new) drive usually resolves
the issue. I have since started to avoid "green" drives due to this issue.
