Not sure if it's destrip or destripe but it's basically like puzzle you take a block from each drive according to the layout you are using e.g. Left symmetric and then write it down in that order computing missing blocks from parity blocks - this way you would write an image which you can mount without using mdadm. Data restoration companies are using this technique.
