Devices can be of different sizes. However, if one drive in a RAID configuration is bigger than the others, this extra space will not be used. Someboot loaderssuch asSyslinuxdo not support multi-device file systems. Btrfs does not automatically read from the fastest device, so mixing differen...

This negates the purpose of increased redundancy and just wastes filesystem space without providing the expected level of redundancy. The duplicated data/metadata may still be useful to statisticall...
