In this video I take a look at dRAID in ZFS. dRAID is a variant of RAIDZ that allow for much faster rebuilds and better uses of a hot spare drive. In this video I compare the rebuild times to a RAIDZ array, and look at performance differences. I also cover how to create a dRAID array in ZFS, and the different parameters that need to be set.
