Review the table below for an overview of the different RAID modes:
|RAID mode||Capacity||Protection||Speed||Factory default|
RAID 0: RAID 0 is the fastest RAID mode. In a RAID 0 array, the available capacities of each hard drive are added together so that one logical volume mounts on the computer. It offers the best performance but no data protection should a hard drive fail.
RAID 1: RAID 1 provides data protection since all data is written to each hard drive at the same time. In the event of a single hard drive failure, data remains available on the other hard drive. Due to the time it takes to write the data twice, performance is reduced when compared to RAID 0. RAID 1 is a good choice when safety is more important than speed. However, RAID 1 also reduces the available drive space by 50% due to the need to write every bit of data to each hard drive.
You can check the current RAID level in LaCie Desktop Manager (see LaCie Desktop Manager) or by using the RAID select button.
