Arguably the problem is they will have differing performance albeit
the same specs. Does this matter in the grand scheme of things for
most RAID environments? I wouldn't think so. I've seen RAID1 setups
failing at the same time with the same drives installed- problem is if
you buy from the same place you're pulling from the same batch, at
minimal one should mix it up to some extent.
