1.5.4 Disk Spanning (SPAN)
The drives show up as one volume, combining the storage capacity of all drives into a single large
volume. Spanning is an array (not RAID) that is written sequentially across the drives. By itself, it
does not provide any performance or redundancy benefits.
HDD
2, 3 or 4 drives
1.5.5 Disk Striping with parity (RAID 5)
The drives show up as one volume but the total capacity, depending on the drive with the smallest
capacity, is the combined size minus the size of one drive. RAID 5 uses block-level striping with
parity data distributed across all member disks and therefore provides the perfect balance between
high performance and data integrity. When one hard drive fails, it can be replaced and the data
rebuilt automatically.
HDD
3 or 4 drives
1.5.6 Non-RAID (IND)
The drives show up as independent volumes and no RAID array is created. This setting is ideal for
drives with different capacities, without having to create a single large volume (disk spanning).
HDD
1, 2, 3 or 4 drives
1.6 About Data Backup
To protect your files and help prevent the loss of your data, we strongly recommend that you keep
two copies of your data, one copy on your Hydra and a second copy either on your internal drive or
another storage media such as CD, DVD, Tape or an additional external drive.
Any loss or corruption of data while using the Hydra is the sole responsibility of the user, and under
no circumstances will the manufacturer be held liable for compensation or the recovery of this data.
