Raid 0/1 they will be fine. Raid 5 not so much. Depending on the actual ones you ended up with they may work, or may constantly drop out of the raid set due to tler. I have a set of WD Black drives that worked fine in Raid 5 until I had to rma one, the one I got back would not work and I ended up stuck with them not being able to use for my original purpose.
Some of these drives you can change the tler settings, some you can not. I would not bother with WD drives except for the RE series if you are trying to use them for another other then Raid 0/1. WD will just state you are out of luck if they don't work in any config other then that as no other configs are supported by them.
If you google WD Green drives and raid, you find loads of information about these issues.
