Does Bitlocker in Windows 8.1 Pro or Windows 10 Pro support RAID 0 drive configuration? RRS feed

  • Question

  • My laptop has two SSD drives that run in RAID 0 configuration (so it's hardware RAID, not software RAID, but specifically RAID 0, where data are stored across two drives, not mirrored).

    I am currently running Windows 8.1 Pro 64-bit and ran into some difficulties when I turned on Bitlocker. I was able to get my computer back to functioning, and Bitlocker says that my drive is now fully encrypted, but I have an error message from Intel, which is how we discovered that my drive is really two drives with RAID 0. I'm wondering if anyone knows much about this. Specifically:

    Does Bitlocker in Windows 8.1 Pro support RAID 0 -- should I trust that it's actually fully encrypting my data and won't cause problems going forward, e.g., if I de-encrypt and re-encrypt to change the Bitlocker settings or upgrade my OS?


    Would upgrading to Windows 10 Pro, which I haven't done yet but plan to do eventually, result in Bitlocker working better with my RAID 0 configuration (e.g., is RAID 0 newly supported in Windows 10 Pro?)?

    I haven't been able to find information about Bitlocker and RAID 0 that is current enough to answer my questions.

  • Hi,

    According to TechNet document, hardware-based RAID is supported for BitLocker, however software RAID is not supported. For your reference: https://technet.microsoft.com/en-us/library/ee449438%28WS.10%29.aspx

    Moreover, Windows 10 remain support RAID 0, just in case please backup Windows before upgrade.
