Not always, depends on the controller, and method or erasure, sometimes it just removes the RAID configuration from the controller, and the data remains in tact on the disk.

we use Dban to wipe disks

No, it never deletes data.  It deletes a few MB of metadata that is external to the file system.    Every byte of your existing data survives the process.  It is just that the controller no longer knows that the disk is part of a RAID1.
