How to create pool with space in Storage Spaces on Windows 10 

Here's how you can start creating a pool and storage space on Windows 10 using Storage Spaces with Settings and Control Panel.

Parity storage space on Windows 10

Storage Spaces is a feature available on Windows 10, which allows you to group physical drives into one logical storage that you can expend, adding more drives and protect the data with different protection levels.

On Windows 10, Storage Spaces supports several RAID-like features, including “simple” to increase storage performance, but does not protect files against hardware failure (requires two drives minimum). On the other hand, the “two-way mirror” requires two drives and offers protection against failures since the data is copied in multiple drives, and there is a “three-way mirror,” but it requires five drives.

Storage Spaces also offers the “parity” resiliency option, which requires at least three drives, and it provides storage efficiency and protection against failures by copying data in multiple places. If you want to protect data against two drive failures, then there is the “dual parity” option, but it requires at least seven drives.

In this guide, you will learn how to create a pool and storage space using the Control Panel and the modern Storage Spaces experience in the Settings app of Windows 10 (build 21286 or higher).

How to create Storage Spaces pool and space using Settings

The Storage Spaces experience in the Settings app is available starting with build 21286 and higher releases. If you are not using this version, you can still complete the task using the Control Panel instructions below.

To create a pool and storage space in Storage Spaces, use these steps:

  1. Open Settings on Windows 10.

  2. Click on System.

  3. Click on Storage.

  4. Under the “More storage settings” section, click the Manage Storage Spaces option.

  5. Click the Create a storage pool and Storage Space option.

  6. Confirm a name for the storage pool.

  7. Select the drives to create a storage pool.

    Quick tip: The number of drives you need will depend on the resiliency level you want to use.

  8. Click the Create button.

  9. Under the “Name” section, confirm a name for the storage space.

  10. Under the “Size & resiliency” section, specify the size of the space.

    Quick tip: If you plan to dedicate all the available capacity to the storage space, you can leave the default size. You can also make the storage larger, and when space starts to run low, you can add more drives to extend the storage.
  11. Use the drop-down menu, and select the resiliency option, including:

    • Simple – requires at least two drives, and there is not data protection.
    • Two-way mirror – requires at least two drives, and there is data protection in the event of one drive failure.
    • Three-way mirror requires at least five drives and offers data protection of up to two drive failures.
    • Parity requires three drives. Offers data protection and performance.
    • Dual parity – requires at least seven drives. Offers data protection with up to two drive failures and performance.

  12. Click the Create button.

  13. On the New volume page, specify a label for the drive.

  14. Specify a letter for the drive.

  15. Select the NTFS option for the file system.

    Quick tip: You can also access the Advanced settings to mount the drive as a folder, specify the allocation unit size, and enable compression.
  16. Click the Format button.

Once you complete the steps, the new drive will appear in File Explorer to store data. If a drive fails, the storage and data will be available, but you will need to replace the hard drive in question as a second drive failure will cause data loss.

How to create Storage Spaces pool and space using Control Panel

To create your first drive pool and space with Control Panel, use these steps:

  1. Open Control Panel.

  2. Click on System and Security.

  3. Click the Storage Spaces option.

    Control Panel Storage Spaces option
    Control Panel Storage Spaces option
  4. Click the Create a new pool and storage space option from the left navigation pane.

  5. Select the drives that will be participating in the pool.

    Create pool select drives
    Create pool select drives
  6. Click the Create pool button.

  7. Under the “Name and drive letter” section, confirm a name for the storage space.

  8. Specify a letter for drive.

  9. Select the NTFS option for the file system.

  10. Under the “Resiliency” section, use the drop-down menu, and select the resiliency option, including Simple, Two-way mirror, Three-way mirror, Parity, or Dual parity.

  11. Under the “Size” section, specify the size of the space.

  12. Click the Create storage space button.

After you complete the steps, the pool and space will be configured, creating a new drive available in File Explorer with the letter and label you specified.
