[. . . ] RAID 5 is useful for people who need performance and constant access to their data, like video editors. In RAID 5+Spare disk failure does not require immediate attention because the system rebuilds itself using the hot spare, but the failed disk should be replaced as soon as possible.

Changing the RAID Mode The 4big comes preconfigured in RAID 0 mode. Before you change the RAID mode of the LaCie 4big, familiarize yourself with the 4big's RAID modes. IMPORTANT INFO: Changing the RAID mode destroys data stored on the LaCie 4big. If you have saved data on the drives, back up data before following these steps. To change the RAID mode: 1. Unmount or safely remove the 4big Quadra volumes from your computer, disconnect the interface cable and switch off the 4big. To enter RAID modification mode, turn ON the 4big (do not select "AUTO") and simultaneously press the front LED on button for 15 seconds. Push the + or - buttons on the RAID mode selector until the desired RAID number appears. NOTE: 0=RAID 0, 1=RAID 10, 2=Concatenation, 3=RAID 3, 4=RAID 3+Spare, 5=RAID 5, 6=RAID 5+Spare, 7=N/A. NOTE: Although the number 7 appears in the RAID selector, no RAID changes will take effect if 7 is selected. Validate the mode by pushing the front LED button. Connect the 4big's interface cable. IMPORTANT INFO: You must partition the disk drives after changing the storage policy configuration. Partitioning the Disks. on auto off Fig. 3. 2 CAUTION: Your LaCie 4big comes preconfigured in RAID 0 (Fast) mode. RAID 0 allows access to the whole storage capacity but does not provide any security. If a drive fails, all data will be lost. If you are concerned about data security, LaCie highly recommends a RAID 10, 3, 3+SPARE, 5, or 5+SPARE configuration. About RAID Modes, for more information.
