Manage RAID
Your LaCie 2big Dock can be configured as RAID 0 or RAID 1. Each RAID level has its own advantages:
RAID level Capacity Protection Speed
Factory default
RAID 0
100%
None
Excellent Yes
RAID 1
50%
Excellent
Good
No
RAID 0—Data is not duplicated on both hard drives in RAID 0. This results in faster transfers and more
storage, since the full capacity of both drives can be used to store unique data. However, RAID 0 lacks a very
important feature: data protection. If a hard drive fails, all data in the array is lost.
RAID 1—RAID 1 provides greater safety since data is duplicated on each disk in the array. If a single disk fails,
the data remains available on the other disk. However, this comes at a cost—since the same data is written
to each drive, copying data takes longer and overall storage capacity is reduced by 50%. RAID 1 is a good
choice when safety is more important than speed or disk space.
