Hydra S2

Maximize your storage capacity with four 3.5" SATA hard drives with the Hydra 4-Bay SATA Enclosure. An ultra durable aluminium casing provides efficient heat dissipation, plus an extra large powerful rear fan keeps your hard drives cool during long hours of operation. Advanced RAID technology provides extra protection for all your valuable data content. The Hydra will surpass all your high performance storage needs.

 

Massive Hard Drive Storage
The Hydra is designed to house two or four 3.5" SATA hard drives with the option to setup your drives with different RAID configurations. Use it as a reliable backup for your important data with RAID 1/10, for optimal performance and speed with RAID 0, or simply combine multiple drives in one location to create one large volume with JBOD. The Hydra comes with a removable hot swap rack, making installing and replacing the hard drives quick and easy.

 

High Speed Connection
The Hydra S2 comes with a choice of two different interfaces. The fast eSATA connection where maximising transfer speed is most important and the more common USB 2.0 High Speed connection for flexibility to access your data on workstations that do not offer eSATA. To keep your drives cool, the Hydra uses smart fan technology. It automatically regulates fan speed according to the internal temperature. This function plus the rubber padded feet not only optimises cooling but also reduces the noise level.

RAID Setup
Note: Changing the RAID setup will require you to re-format the drives. Make sure you backup all data before doing so!
BIG 2 or 4 Hard Drives	JBOD (spanning) The drives show up as one large single 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. Use this if you have installed 2 or 4 hard drives with different capacities.
FAST * 4 Hard Drives	RAID 0 (striping+striping) The drives show up as one large single volume. This mode requires 4 identical drives to implement. Used where speed is the primary objective, RAID Level 0 (also called striping) is not redundant. This form of array splits each piece of data across the drives in segments; since data is written without any form of parity data-checking, it allows for the fastest data transfer of all other modes. However, if one drive becomes damaged, the whole array can become corrupted.
SAFE * 2 or 4 Hard Drives	RAID 1 (mirroring) The drives show up as two volumes, each representing one set. This mode requires 1 or 2 sets of 2 identical drives to implement. RAID 1 creates an exact copy (or mirror) of a set of data on the second drive. This is useful when reliability and backup are more important than data capacity. The available capacity to the user will be 50% of the total capacity for each set but when one hard drive fails, it can be replaced and the data rebuilt automatically.
SAFE II * 4 Hard Drives	RAID 10 (mirroring+striping) The drives show up as one single volume. This mode requires 4 identical drives to implement. RAID 1 creates an exact copy (or mirror) of a set of data. This is useful when reliability and backup are more important than data capacity. The available capacity to the user will only be as large as 50% of the total capacity of all drives combined but when one hard drive fails, it can be replaced and the data rebuilt automatically.
Remarks	* For the FAST and SAFE mode, hard drives of identical capacity and make are recommended! If the capacity is different, the total amount of the space that can be used will depend on the drive with the smallest capacity.
