The problem with using different brands is that my controller doesn't make it clear which ports are used for each side of the mirror and/or stripe. To further confuse things, Seatools shows a different serial number order than the RAID controller BIOS screen does (and it's a minor difference, like position 2 and 3 swapped).
I wonder if it's better performance wise to match brands for the mirroring or striping portion... I would imagine the former would make more sense, since the seek speed for mirrored writes would be near identical.
Anyway, when I purchased the original 4 drives they came from 3 different countries, but it didn't really make much difference in the end: they've all been replaced due to failure.
