:Synchronizing a volume can take from five minutes to many hours, depending on
The level of RAID
The capacities of the hard drives in the volume
(The NAS's available resources (concurrent tasks such as backups or downloads will slow synchronizing
For example, creating an unprotected RAID volume takes less than five minutes while RAID 6 with large
.capacity hard drives can run for many days. You can access the volume while it is synchronizing
:It is important to note that during synchronization
NAS performance is reduced due to a heavier demand upon the CPU RAID
protection is not available until the synchronization is complete
Older hard drives can fail, especially models that are not constructed for NAS
Single-disk and unprotected volumes: Expansion
Important info on NAS backup: It is recommended that all users back up data to DAS or another

NAS as further protection against the loss of a hard drive and secondary points of failure (e.g.
.hardware, network, etc.). See Backup Manager for details
Removing healthy hard drives from an unprotected
volume
:An unprotected volume can be
SimplyRAID single-disk
RAID 1 single-disk
JBOD
RAID 0
Removing a healthy hard drive from an unprotected volume while the NAS OS device is powered on will delete
all of the volume's data. While removing healthy hard drives is not recommended, you can avoid losing data by
.shutting down the NAS first. Return the hard drives to their proper bays before powering on the NAS
