It is really odd that two different makes of drives failed at the same time. When I build large arrays I always use at least two different manufacturer's disks together. I found out the hard way that within a single manufacturing batch all the drives have about the same life expectancy. I had a five disk RAID5 with a hot spare. When one of the drives failed it started the rebuild onto the spare. While thrashing about to recreate the missing parity data a second drive failed, lost everything at that point. That's not supposed to happen either.
