10.3. Sequential Read Performance on SMB Volumes
The sequential read performance of ReadyTIER on the low tier volume makes this configuration the best overall performer for
sequential operations.

11. Configure a ReadyNAS
This section provides some information on configuring a ReadyNAS system. It includes:
• What volumes are configured by default
• An introduction to the volume wizard
• How to manually create a new volume
• An introduction to parity on ReadyNAS systems
• How to expand an existing volume
• How to add RAID groups
• How to add a tier
• Information about global spares
11.1. Default Volumes
On initial setup, the ReadyNAS automatically creates volumes based on the number of drives installed in the unit.
The table below indicates the default number of volumes and RAID levels for different installed drive numbers. This is also
the recommended RAID configuration should you choose to create the RAID groups yourself. The recommendations below
provide a good balance between performance, capacity and redundancy for most use cases such as backup, file sharing,
surveillance, and virtualization.
Note: For virtualization applications with high random IOPS (such as multiple high traffic volume mail servers), we recommend
RAID 10 for best performance.
