Expanding on that: It is generally a bad idea to use 100% drives from the same manufacturing batch because their eventual failures are likely to be very close together Similarly it is a good idea to use a mix of drives from different manufacturers, in order to try and spread any failures out over a longer period of time. I know of very few hardware suppliers who mix batches in their raid arrays and of none who mix manufacturers. So far this hasn't been a problem for our hardware arrays, but I prefer to mix things up when building software arrays.
