Pools
2 minute read.
Last Modified 2024-03-19 08:38 EDTTrueNAS uses ZFS data storage pools to efficiently store and protect data.
For more on ZFS storage, see ZFS Primer.
We strongly recommend users review the available system resources and plan the storage use case before creating a storage pool.
- Allocating more drives to a pool increases redundancy when storing critical information.
- Maximizing total available storage at the expense of redundancy or performance entails allocating large-volume disks and configuring a pool for minimal redundancy.
- Maximizing pool performance entails installing and allocating high-speed SSD drives to a pool.
Determining your specific storage requirements is a critical step before creating a pool.
The articles in this section provide information on setting up system storage, which includes adding, importing or managing pools.
