Silverstone RS431U Four Bay 1U Rackmount Tower with USB 3.0 and eSATA Interface

RS431U supports Configurations such as (RAID 0, 1, 3, 5, 10, Combine, Clear RAID) it does not support JBOD they will not show as individual drives. Raid 0: The drives are shown as one large single volume but the total size will depend on the drive with the smallest capacity. This setting is used where speed is the primary objective but 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. On the downside, if one drive becomes damaged, the whole array can become corrupted. Raid 1: Two drives show up as one volume but only 50% of the total capacity, depending on the drive with the smallest capacity, can be used. RAID 1 creates an exact copy (or mirror) of a set of data on the second drive. This is useful when reliability and backup take precedence over storage capacity. Should one hard drive fail, it can be replaced and the data rebuilt automatically. Raid 10: RAID 10 is a high level data storage option where at least 4 hard drives are required. The total capacity is twice the size of the drive with the smallest capacity. Under Raid 10, all four hard drives will perform RAID 1 where the first two and the last two hard drives are mirror images of each other and than it will perform RAID 0. This will be shown as one hard drive with high speed performance and a secure backup function. Raid 3 and 5: The parity information on RAID 3 is stored on a single drive, where RAID 5 stores the information across the entire array. In both cases, the original data is secure. Combine: Combine mode will add all existing hard drive into a single hard drive with large capacity.
