So true on raid 10, amazing how many people don’t realize that, and friends don’t let friends use raid 5. With the thousands of servers we have online in our DC I have seen too many raid 5 failures during rebuild. Go with atleast raid 6 or raidz3 if using zfs.

Raid10 means if you lost 2 disks you're still OK. Just get a replacement in there already!
