Public bug reported:
When setting up a Linux software RAID array inside the Ubuntu Server
install routine (which uses mdadm), beyond the ability to specify array
members and personality, there is no ability to tweak the chunk size.
The chunk size defaults to 512KB which would be suitable for a very
specific set of uses but quite suboptimal for others. The underlying
hardware is also a factor, as SSDs benefit from a much smaller chunk
size due to high performance at high queue depths regardless of use
case.
