We are looking at converting about 12TB of 21TB of disk from Mod 9 to 27 (32,760). We are doing those storage groups that have 250GB of data in them so they use 10 M27s and adding another M27 adds 10% or less. Two storage groups have 1,600GB so adding 9 or 29.4 GB are very minor. We have some storage groups with a mix of M9s and M27s and we have not seen any problems.
