I started my home server off with a 3-drive RAID-5, with 3 identical drives with consecutive serial numbers. One started giving building pending sectors within a month, another after 9 months. By now I have 6 drives in RAID-6 from 3 manufacturers with varying power-on-hours and no two from the same batch. Cheers, John.
