How well does this cope with drives of different capacities?
Eg. I have a Synology NAS that I started with 2TB drives and now has a mixture of 2, 3 and 4 TB drives in a RAID 6 configuration, this is easy to manage and as soon as the 4th drive of the largest size is accommodated the full capacity is available.
Will this Array make use of all the capacity when the minimum number of larger drives are added? Eg. if it is in RAID 5 and has three 4 TB drives will I get 22TB available in one volume when I insert three 5 TB drives?
