#BUSTED Mythbusting with ZFS: "Single Drive IOPs Limitation per RAIDZ vdev"

Every second week, we will be releasing a tech tip video that will give users information on various topics relating to our storage products.

If there is anybody on our team that likes to bust myths in the storage world, its our very own Mitch Hall!

For this week's tech tip video, Mitch wants to talk about mythbusting some of the "storage wisdom" surrounding ZFS. Anyone who uses ZFS would have likely heard "you will only get the IOPs of a single drive in a RAIDZ vdev". Is this statement true? Or, can this myth be BUSTED? Check out today's video to find out.
