3.2. Changing the RAID Mode

available to the 2big USB 3.0 before following the steps below.
IMPORTANT INFO: Changing the level of RAID will require
that you format the LaCie 2big USB 3.0. Please back up any
data stored on the LaCie 2big USB 3.0 before following the steps
below.
CAUTION: Your LaCie 2big USB 3.0 comes preconfigured in
RAID 0, which provides faster transfer rates and allows access to
the whole storage capacity. Unlike RAID 1, it does not provide
any security. If a drive fails, all data will be lost. If you are con-
cerned about data security, LaCie highly recommends changing
your 2big USB 3.0 to RAID 1. See section
for more information.
