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…

Fantastic video. I really appreciate the RaidZ3 9 disk + spare rebuild times – and the mirror rebuild times. Right now I have data striped across mirrors (Two mirrors, 8TB disks) that is starting to fill up and I've been trying to figure out the next progression. Maybe a 15 bay server – 10 bays for a new Z3 + 1 array, leaves enough space to migrate my current data to the new array.
If I had like 24 drives, I'd certainly use dRAID. Sequential resilver….just great, especially with today's drive capacities.
imagine: I only use mirrors and stripes but I am still watching it 😉
