Raid Configuration Times; Automatic Power Off And Raid Safe Synchronization - LaCie 2big Thunderbolt User Manual

RAID configuration times

The table below provides estimated times to configure the RAID.
RAID Time to complete
FAST Less than a minute
SAFE Several hours to one or more days (see note below)
JBOD Less than a minute
The time to complete the RAID SAFE synchronization is based upon total hard drive capacity. Though the time to
synchronize may take several hours, you can begin using the volume immediately by initializing it with your
operating system's disk utility (see Formatting).
Performance may be affected during RAID synchronization.

Automatic power off and RAID SAFE synchronization

In general, the LaCie 2big powers off when the computer is shut down. However, the device remains powered
on if it is in the midst of a RAID SAFE synchronization.
