Some people are saying good things about raid 10 (sriping and mirroring).

Any comment?

Glad to hear you learned the lesson the easy way about stripe sets.
With RAID 0 you have greater speed but if either of the drives fails
you lose ALL your data.  And you can only access it through a RAID
controller of the same type.  RAID 1 (mirroring) is what you want for
data security, but it comes at a price since you need 2 drives to do
the job of 1 and you lose some write speed, depending on your
controller.

As all things in life, the good stuff is never cheap. RAID 10 requires at least 4 harddisks at 50% capacity and can be terribly expensive to migrate upwards without an intelligent RAID controller that supports RAID extending.


Lately I have been a bit disappointed with IDE RAID at least with backplanes. Ah well, we will see. My desktop based RAIDs are fine and I recently broke my RAID10 into a RAID1 with 2 JBODs for much easier migration and backups.
