Using RAID 1 is limited by the size of your physical disk. One option is to write your backup file to multiple independent RAID 1 arrays, which may further increase I/O throughput by using different controllers or channels.

Using RAID 5 causes some write performance loss, because parity verification is required. If you really want to make the backup process run faster, this raid level may not work.
Raid 10
With the raid 10 solution, you will get the advantages of both RAID 0 and RAID 1.
