3.4 raid0 (faSt)

RAID0 (Fast) Configuration – 010

RAID0 (FAST) storage mode distributes data across both hard disks in a striped array. While in

RAID0 (FAST), data is transferred to both disks simultaneously, in parallel, improving data transfer

speed but offering no data redundancy. Kanguru QSX creates a single virtual volume that is striped

across both hard drives, with a storage capacity that is equal to the sum of both hard disk drives.

Warning! If one hard drive fails, all data stored on both hard drives will be corrupted. RAID0 doubles

your potential for data loss, since if either one of the two disks fails then all your data will be corrupted.

Do not attempt to replace the faulty drive. Doing so will void the warranty. If one of your hard drives

fails, please contact Kanguru Solutions Tech Support at 508-966-4245.

Before using the Kanguru QSX in RAID0, you first have to format your hard drives. For more

information, please see section 2.4 Formatting Large Volumes, p.9.
