Create a New Storage Pool

Important:

  • Before you start, make sure there is no important data on the drives that the storage pool is going to be created on. All existing data will be deleted during the creation process.
  • Go to the HDD/SSD page and make sure the status of each drive is Normal or Not Initialized.

To create a storage pool:

  1. Launch Storage Manager.
  2. Go to Storage Pool and click the Create button.
  3. Choose the storage pool type:
    • Better performance: This type of storage pool supports only a single volume but provides better performance.
    • Higher flexibility: This type of storage pool supports multiple volumes and the RAID Group feature.
  4. Enable secured storage pool:
    • Secured Storage Pool:
      • This Storage Pool consists of SEDs only, and the SEDs will be protected by authentication.
      • The Hot Spare drives and SSD cache must be SSDs as well.
    • Normal Storage Pool:
      • This storage pool is not restricted to SED usage but is not protection by authentication either, and only SEDs which are not protected by authentication can be used.
      • Once a normal storage pool is created, you will not be able to enable SED authentication.
  5. Configure storage pool properties:
    • Storage pool description: A description of this storage pool.
    • RAID type: Different RAID types offer varying levels of data protection. For more information, please refer to General.
    • Minimum number of drives per RAID: The minimum number of drives required for the selected RAID Type.
    • Maximum number of drives per RAID: A higher number of drives per RAID increases the probability of RAID failure. We recommend adjusting the number limit of drives in a single RAID and using RAID Group to strike a balance between data security and storage pool capacity.
    • RAID Group feature: Whether the RAID Group feature is supported by the selected RAID type. While a single RAID has a restriction on the drive number, the RAID Group feature allows your storage block to be composed of multiple RAIDs, thus increasing its capacity and drive redundancy. RAID Group is supported by RAID 5, RAID 6, and RAID F1.
  6. Follow the remaining steps of the wizard to finish creating the storage pool.

Note:

  • The maximum number of drives per RAID and RAID Group feature are available on specific models only. For more information, please visit Synology website.
  • The maximum number of drives per RAID can be changed only if the selected RAID type supports the RAID Group feature.
  • If the RAID type of the storage pool is RAID 5, RAID 6 or RAID F1, the system will perform RAID Resync to the storage pool to enhance access speed and to improve data resilience.
  • When creating a storage pool, you need to select which controller should the storage pool mount on. After the storage pool is created, you can change and mount the storage pool on another controller by going to Storage Pool > Action > Change Controller.
