Based on statements from the openZFS documentation where it is described
as providing "the same level of redundancy and performance as raidz" [0].

 in regard to IOPS with a lot of bandwidth. How much bandwidth depends on the
 size of the RAIDZ vdev and the redundancy level.
 
+A 'dRAID' pool should match the performance of an equivalent 'RAIDZ' pool.

 For running VMs, IOPS is the more important metric in most situations.
