Single: requires 1 device only, it's also the only way of using all space from different size devices, BTRFS equivalent of JBOD, no performance gains vs single disk or RAID1 -dconvert=single -mconvert=raid1 RAID0: requires 2 device, best performance, no redundancy, if used with different size devices only 2 x capacity of smallest device will be available, even if reported space is larger. -dconvert=raid0 -mconvert=raid1 RAID10: requires at least 4 devices, to use full capacity of a 4 device pool they all need to be the same size. -dconvert=raid10 -mconvert=raid10 RAID5/6 are still considered experimental so use at your own risk RAID5: requires at least 3 devices. -dconvert=raid5 -mconvert=raid1 RAID6: requires at least 4 devices. -dconvert=raid6 -mconvert=raid1 Many thanks to The Lime tech team for giving us unRAID Jonnie Black for his info on btrfs raid modes Music credit firmament by Kevin MacLeod is licensed under a Creative Commons Attribution licence (https://creativecommons.org/licenses/...)
