I go the exact opposite way these days, I buy 3 drives from 3 different brands and run them in a ZFS raidz. This reduces the risk of all the drives failing at the same time (which can happen with any batch of disks) but also makes it easier to determine which physical drive needs replacing when you have a failed disk in a NAS (since each disk is unique).
