Storage Spaces Dual Parity

    Storage Spaces Dual Parity


    I have Windows 8, my OS is on a separate drive and I have placed 8x2tb drives into storage spaces parity. I wanted to use dual parity. No option for dual parity came up and windows did not automatically build a dual parity, as far as I'm aware.

    Storage Pool says using 10TB of 14.5TB
    Drive Tools says 7.82TB free of 14.4TB
    Properties says Used space 6.67 Free space 7.82

    I'm interested to know if I'm already using Dual Parity or if I'm not how to get the option to use it? Ive done a great deal of searching on the net for an image of the option. Or concrete proof that someone else is using the option and have found none.

    Thanks for the links Berton I have read these and not found a conclusive answer. Did you see something of interest amongst these links that I may of missed?

    The only thing that caught my attention besides the references to Windows Server 2012 is somewhat of a kinship to RAID.

    I thought it was interesting it said "It is also possible to use dual-parity in Windows Server 2012 R2" in the first link

    Which may mean you can't use dual parity in Windows 8

    Your links gave me the idea to type "
    dual parity only on server" into google which found this link https://social.technet.microsoft.com...winserverfiles

    Which is someone else asking the same question but as close as Ive come to answer to. Does Windows 8 have Dual Parity?

    Dual parity is only available in the server product.

    Thanks for clearing this up. Do you recommend using Dual Parity for 8x2TB hdd?

    I've heard that raid 5 is not recommended for more than 5 HDD because of the likely hood of an error during rebuild. I've also heard that Parity on Windows 8 is not Raid5 but I would like to know if I'm likely to experience any errors.

    Hi there

    Storage spaces work just great -- and you don't need to use the same size HDD's either. I wouldn't have 8 in the mix --although it depends on the size you want to create -- it might be better for example to create TWO pools of 4 X 2 TB.

    Parity is fine -- unlike mirroring you only need 1/2 of the space that a full mirror uses ("Striping").

    Depending on what you need the space for you could even risk having no redundancy at all. I have data space of my multi-media files with no redundancy. My Multi-media set doesn't change much and I have an archive set in case of trouble. HDD's are fairly robust these days and newer ones don't normally suddenly fail.

    Incidentally if you start with a smaller storage space you can ADD volumes later if you need more space so you don't have to allocate the whole set of 8 X 2 TB in the beginning.

    For shared / remote computers / LAN the storage space appears as a Single Drive so sharing is handled quite normally.

    RAID requires ALL volumes to be the same size. Storage spaces are much more flexible. You can of course use full mirroring if you want but it's not normally necessary.


    Read the link again it's quite helpful.

    Thanks for the info. I have 8x2tb drives and I will be storing a large amount of video footage indefinitely. I want the safest option for storing my clients footage.

    I have read that raid 5 fails during rebuilds when using a lot of HDDs. I'm assuming Single Parity on storage spaces is similar to Raid5.

    I'm not interested in using raid5. I am worried about losing all my data during a storage space parity rebuild from a failed drive. Would I be better off switching to Windows Server2012 Dual Parity because I'm using 8 HDDs? Are you saying I should switch to two lots of 4x2tb instead of one 8x2tb?

    Thanks again for your help Jimbo. If this seems like a double post I'm re wording my question here because it seemed like you were telling me the benefits of storage spaces vs raid and not answering my question. My apologies if I have misunderstood.
