    When would it be a good idea to use a RAID 0? If you are always faced with total failure, what's the point?

    When the data doesn't matter, but speed does. It used to be popular with video game systems, for example, where load time mattered a lot, but it was easy to install again should the data be lost.

    RAID 0 is common in caching systems where data needs to be stored temporarily, but never matters. Basically, anytime that you'd be okay using just a single disk, you might be okay using RAID 0. If you think about it, if you have only a single disk and anything fails, all is lost. That's how your desktop is, for example. So if you are already okay with that risk, you might be okay with double the risk but twice the speed and capacity, too.

    It's for "ephemeral" storage.
