Your NSA has a single bay for a SATA (Serial Advanced Technology Attachment) hard disk. The 
firmware installed during hard disk initialization (

) automatically creates a 

JBOD volume on your SATA hard disk. JBOD is the default storage method if you are using a single 
hard disk for your NSA. 

This JBOD volume shows up in the Storage > Volume screen (

) as 

follows.

When you attach an eSATA hard disk to your NSA, you can configure this volume as: 1) a backup to 
your SATA hard disk (RAID 1); or 2) as a separate storage drive (either another JBOD or a PC 
Compatible Volume). 

This storage method allows recovery of data if your hard disk fails. To create a RAID 1 volume, you 
must connect an eSATA hard disk to your NSA. There are two ways to create a RAID 1 volume: 

• Click the Migrate button - This is a quick way to create a RAID 1 volume. Use this to 

automatically synchronize data in the internal hard disk to the eSATA hard disk. 

• Click the Create a SATA volume button - Use this if there are no existing volumes in your NSA.

Do the following steps to create a RAID 1 volume.

Once you attach the eSATA hard disk to the NSA, the Storage > Volume screen shows the 
Migrate button.
