That is sort of true. With two physical disks RAID0 turns them into one device. In theory your OS reads/writes to both at the same time, speeding things up by a factor of two. In reality the speedup is far less than two. And since both disks have been turned into one device, you have no place to put a mirror. And another bad point about RAID0 is that if one disk fails, you lose both disks, because half of file was written to one disk and the other half to the other. Trying to recover means you have to match all the parts; not generally possible.
John, Thanks for confirming. That's what I thought RAID0 did and I assumed the HOW-TO was providing approaches to flavors other than RAID1, which has the redundancy I want. Root's crontab runs backups at 00:30 each night. Since only changes are written to the vaults I'm not concerned about speed. Stay well, Rich
