we use several of this kind of boxes (but with 45 trays) and our
experience was that the optimum volume size was 12 hdds (3 X 12 + 9)
which will reduce the 45 disks to a actual size of 37 disks (a 12 disk
volume is 40 TB size ... in event of a broken hdd it takes 1 day to
recover.. more than 12 disks and i dont (want to) know how long it would
take) and we don't use hot spares.
