Default Shared Folders
When the hard drives are formatted, the NAS will create the following default share folders:
 home: The user's home folder.

 RAID 0 Striping Disk Volume: RAID 0 (striping disk) combines 2 or more hard drives into one
larger volume. The data is written to the hard drive without any parity information and no
