when equipping a storage system, it does make sense to use disks from different manufacturers, different models, and different vintages (manufacturing batches).

equipping a storage system with disks all of the same make, model, and vintage is invoking the statistics gods to strike failure all at once (or close enough that you won't be able to keep up with the rate of failure and time to rebuild)

personal experience: attempting to rescue a failing 192 disk system containing disks all of the same make and model. wearisome.
