 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' should match the performance of an equivalent 'RAIDZ' pool.

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

applied with a small change: added 'pool' after dRaid for better 
readbility, thanks!
