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.
