I have some questions relating to drive expansion on SHR/BTrFS, QTS/Ext4 and QTS-hero/ZFS. On each of these combinations, ...
(1) Can you begin with 1 drive without being locked into JBOD, RAID 0, RAID 1 or RAID 5?
(2) Can you begin with RAID 1, and later, easily change/expand to RAID 5?
(3) Can four drives set up as two RAID 1 pairs be easily expanded to a 4-drive RAID 5?
(4) I know that SHR/BTrFS allows expansion with larger drives without loosing their capacity. Can either of the others do this?
(5) In each of the combinations, if an additional drive is added to a RAID 5, can the data be evenly distributed over the whole RAID? ...easily?
Thank you in advance for the assistance.
