    W00t, easy question to close the year 😀 :w00t:

    Not really sure though why a Microsoft resource is so necessary when the question itself is about a pretty universal concept.

    Agreed

  • Can't see the need for a Microsoft reference on a question that's about something universal. But I agree with Tom - I'd never use a Wikipedia reference as sole support for any statement.

  • learnt in begining of college days.. easy one...

  • My Master's degree program won't let me use Wikipedia at all... If it doesn't come from the university library as a scholarly resource, use it at your own risk... 😀

    Yes, 'independent' is misleading - how are disks in RAID 5 'independent' when the data is striped across them? And in RAID 0 the disks are obviously wholly dependent on each other. They're only independent in RAID 1 or RAID 10.

    I know it's all over the web and text books now, but it's wrong. Gartner has a definition on its website headed RAID (Redundant Array Of Independent Disks), which says under RAID 0 'if one drive fails, the entire disk array subsystem is unavailable'??!?

    It's not specific to Microsoft and so doesn't require a Microsoft reference.

    Just to be (even more?) pedantic, 'independent' is not spelt 'independant'.

  • Thanks to you all for your thoughts on my question. It keeps me thinking and learning, which is why I'm here.

    All the best for 2013.

    Dave.
