User Manual

The graphic shows the balance of capacity, performance, and reliabilty for the selected protection level
and number of disks. As you change the RAID level, the graphic updates to show the changed balance.
If more drives than the minimum necessary for the selected RAID level are available, the Number of
RAID Groups, Number of drives for RAID Group, and Remaining drives allocated to Global Spare
fields are active.You can chose to organize the volume with RAID groups, or assign disks to the global
spares pool, or a combination of the two.

Add a Tier to a Volume
You can use ReadyTIER to add SSD drives to an existing volume as a tier. ReadyNAS OS automatically
uses a tier for volume metadata.With some workloads, this can improve filesystem performance.
Depending on the RAID setting of the volume, a minimum number of disks are required to add a tier. The
metadata tier disks need not be the same size as the data disks.You can estimate the size needed by
pointing tor the icon of the volume and checking the volume metadata allocation.
