Why would you want to use dd for this? Dd will suffer from the
following drawbacks:
1. Unused space will also be backed up
2. You cannot restore onto anything except an exact mirror (size-wise)
of the backed-up partition
3. You cannot restore selective files
4. You cannot view the contents of the archive.
Use Tar or even Cpio to back up your data.

Compile the MD driver into your kernel, get the utilities as specified
in the kernel config help
(/usr/src/linux/Documentation/Configure.help) and use them for
achieving RAID 0,1,5
