RAID Options
Here is a list of the RAID options available on the ShareCenter DNS-345
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 makes up
a JBOD RAID can be dierent 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.
