How to Create a New Pool and Storage Space in Windows 10

information   Information
Storage Spaces helps protect your data from drive failures and extend storage over time as you add drives to your PC. You can use Storage Spaces to group two or more drives together in a storage pool and then use capacity from that pool to create virtual drives called storage spaces. These storage spaces typically store two copies of your data so if one of your drives fails, you still have an intact copy of your data. If you run low on capacity, just add more drives to the storage pool.

You can create a simple, mirror (two-way or three-way), or parity storage space:
  • Simple spaces are designed for increased performance, but don't protect your files from drive failure. They're best for temporary data (such as video rendering files), image editor scratch files, and intermediary compiler object files. Simple spaces require at least two drives to be useful.
  • Mirror spaces are designed for increased performance and protect your files from drive failure by keeping multiple copies. Two-way mirror spaces make two copies of your files and can tolerate one drive failure, while three-way mirror spaces can tolerate two drive failures. Mirror spaces are good for storing a broad range of data, from a general-purpose file share to a VHD library. When a mirror space is formatted with the Resilient File System (ReFS), Windows will automatically maintain your data integrity, which makes your files even more resilient to drive failure. Two-way mirror spaces require at least two drives, and three-way mirror spaces require at least five drives.
  • Parity spaces are designed for storage efficiency and protect your files from drive failure by keeping multiple copies. Parity spaces are best for archival data and streaming media, like music and videos. This storage layout requires at least three drives to protect you from a single drive failure and at least seven drives to protect you from two drive failures.

This tutorial will show you how to use Storage Spaces to create a new pool and storage space in Windows 10.

You must be signed in as an administrator to create a new pool and storage space.



Here's How:

1. Add or connect the drives that you want to group together with Storage Spaces.
Note   Note
These drives can be internal or external hard drives, or solid state drives. You can use a variety of types of drives with Storage Spaces, including USB, SATA, and SAS drives.

The number of required drives will depend on if you want to create a simple, mirror (two-way or three-way), or parity storage space. See info at the top of this tutorial for how many drives will be required.


2. Open Settings, click/tap on the System icon, click/tap on Storage on the left side, and click/tap on the Manage Storage Spaces link on the right side. (see screenshot below)
Note   Note
You can also open the Control Panel (icons view), and click/tap on the Storage Spaces icon instead.

4. Click/tap on Yes if prompted by UAC.

5. Select (check) the disks you want to add to the new storage space to create a storage pool, and then select Create pool. (see screenshot below)
warning   Warning
Windows will permanently delete all partitions and files on selected formatted drives (disks).

Be sure to back up anything you do not want to lose to another disk first.

6. Enter a name (ex: "Storage space") you want for this storage space. (see screenshot below step 10)

7. Select a drive letter (ex: "E") you want for this storage space. (see screenshot below step 10)

8. Select a file system you want for this storage space. (see screenshot below step 10)

9. Select a Simple, Two-way mirror, Three-way mirror, or Parity resiliency type you want for this storage space. (see screenshot below step 10)

10. Enter the maximum size you want this storage space can reach, and click/tap on Create storage space. (see screenshot below)

11. The new storage pool and storage space will now be created. (see screenshot below)
Note   Note
The physical drives are the disks you selected in step 5 above.
