Use the Dashboard's RAID Management page to monitor and manage the RAID configuration of your Network Space MAX.
RAID 0: RAID 0 is the fastest RAID mode. In a RAID 0 array, the available capacities of each disk are added together so that one logical volume mounts on the computer. It offers the best performance but no protection should a disk fail.
RAID 1: RAID 1 offers protection since all data is written to each disk at the same time. In the event of a single disk failure, data remains available on the other disk. Due to the time it takes to write the data twice, performance is slightly reduced. RAID 1 is a good choice when safety is more important than speed. However RAID 1 also reduces the available disk space by 50% due to the need to write each bit of data on each hard drive.
The default RAID mode depends upon the model of the Network Space MAX:
|RAID Mode||Capacity||Protection||Factory Default|
|RAID 0||100%||Network Space MAX dual disk|
|RAID 1||50%||Network Space MAX single disk1|
1 Since it has only one disk, the Network Space MAX single disk cannot work in a true RAID 1 configuration that writes all data to a partner hard drive. However, it is shipped “RAID-ready” in preparation for RAID 1. See below for further details on rebuilding a RAID 1 array after adding a second disk.
You can change your RAID configuration at any time. For example, you may have started with a RAID 0 array but decide that you want to move to RAID 1 to protect data stored on the Network Space MAX. The RAID Setup Wizard is an easy tool for adjusting the RAID, offering a few simple steps to suit your needs. However, it is critical that you understand the potential consequences that reconfiguring the RAID will have upon existing data.
If you have discovered that one of the hard drives has failed (see LED Indicators) or the chassis no longer works, please contact your LaCie reseller or LaCie Customer Support. If the product is still under warranty, a LaCie Customer Support representative will instruct you on how to return the drive or casing for replacement. See Getting Help for contact information.
If your LaCie storage device is no longer within the warranty period, please use the directions below to replace a failed disk with a healthy disk purchased from a third party. LaCie recommends selecting a disk that is the same model number and capacity as the one it will replace.
Follow the directions below to remove and replace a failed drive.
Once you have received the replacement drive:
