There is probably a very slightly elevated chance of both drives failing AT SOME POINT, but prematurely, if they are from the same batch and it was a bad batch. I can't see 2 drives failing at the exact same time. If hard drives lasted exactly 1000 hours or something, sure.
As long as you have another copy of your data somewhere else, I wouldn't worry about it. Or if 1 drive fails, get another & rebuild ASAP.
