Section 5 - Knowledge Base RAID Options Here is a list of the RAID options available on the ShareCenter DNS-340L. Standard RAID - creates a single volume for one drive or more drives. JBOD - allows you to create a large virtual disk drive by concatenating two or more smaller drives together. The individual hard drives that make up a JBOD RAID can be different sizes and manufacturers. The total size of the JBOD RAID is the combined total of all the individual drives in the set. RAID 0 - allows you to assign two or more disks as a striped set. Once you create the striped set, you will see it as a single disk drive. But when you write data to the RAID 0 striped set, the data will be distributed across all of the drives that make up the set. Because each disk has less to do, it takes less time to write the data. The same is true when reading data; instead of a single disk having to seek out and then send a large block of data, multiple disks each stream their part of the data stream. As a result, RAID 0 striped sets can provide a dynamic increase in disk performance. D-Link ShareCenter DNS-340L User Manual 431
