RAID and Storage Policies

10. Understanding RAID and Storage Policies

Your LaCie Ethernet Disk RAID supports several

different RAID levels: 0, 1, 5, 5+spare, and 10 (1+0).

This section will help you decide which RAID level is

right for your application.

RAID levels effect the total available storage capac-

ity of the disks in the RAID array. The table below de-

scribes how each RAID levels affect the total storage

capacity.
