Note:
To create a storage space, you’ll have to connect two or more additional drives to your computer – you can’t use your system drive for this. The drives can be either internal or external drives.
You can open the Storage Spaces configuration window from the Control Panel or by bringing up the Start screen with the Windows key, typing "Storage Spaces," clicking the Settings category and selecting the Storage Spaces shortcut.
Select the drives you want to use for the storage space and click the "Create pool" button to continue. You’ll lose any files that are already on the drive – copy any important files off the drives before pooling them. You can add additional drives later.
The resiliency type controls how Windows handles your data. There are four options:
* None: Windows will store only a single copy of your. You’ll lose the data if one of your drives fails, but no space will be used on backups.
* Two-way mirror: Windows will store two copies of your data. If one of your drives fails, you won’t lose your data. This requires at least two drives.
* Three-way mirror: Windows will store three copies of your data. If one or two of your drives fails, you won’t lose your data. This requires at least three drives.
* Parity: Windows stores parity information with the data, protecting you from a single drive failure. Parity uses drive space more efficiently than mirroring, but file access times are slower. Parity is ideal for drives with large, infrequently updated files, such as video files.
