Technical Brief: RAID

7. RAID - Three Disk Server

The directions that follow will help you to create the recommended
RAID configuration for a 5big Storage Server with three disk.
7.1. Three Disk Suggested RAID
Configuration
While it is possible to create Spanned disks or RAID 0 arrays, LaCie
highly recommends mirroring and RAID 5 for optimal protection of
your data. RAID 0 can offer some speed advantages but data will
not be protected across multiple volumes as with mirroring and RAID
5. Users risk losing data if one of the disks should fail with RAID 0.
IMPORTANT INFO: Mirroring and RAID 5 provide solid protection
if one drive in their respective volumes should encounter problems.
However, LaCie highly recommends backing up the data stored on
your professional server regularly in order to guard against worst
case scenarios (i.e. accidental data deletion, malicious programs,
viruses, etc.). LaCie professional servers include USB 2.0 and eSATA
ports to attach desktop drives for use as backup storage. You can
also backup your data to another server on the network.
