    How does parity work?


    Hello all,I am researching Windows Storage Spaces, and I am having a hard time finding how parity spaces work on a technical level. I gather that they require more physical drives and they have slower read and write speeds, but take up less space than mirroring does. However, I don't understand how parity protects you against disk failure.I don't have an issue, I'm just wanting to teach a Windows class at my library and I want to be able to explain everything Windows related.Thank you in advance!

    :)

    Storage Spaces Parity Repair?

    Hi: I'm a newbie here... using an OWC Thunderbay 6 DAS with Thunderbolt 3 for video/photo files using (Win 10 Home) Storage Spaces for the past 6 weeks without problems. Using Parity option in Storage Spaces to emulate RAID 5 protection.

    Today, got Parity Error in Manage Storage Spaces, though all 6 drives show "OK". Both Hard Disk Sentinel and CrystaDiskInfo also show normal drives. No pertinent drive events in Event Viewer.

    From reading other posts from folks with Storage Spaces issues, I'm inclined to "repair" this parity error if possible, and then consider migrating to DrivePool to avoid repetition or other future issues with SS. Can anyone walk me through how to do a parity repair?

    If not doable, then can someone detail a step-by-step process for migrating my 24Tb currently on Storage Spaces to Drivepool? Many thanks!
