TOSHIBA RAID
TOSHIBA RAID (Redundant Array of Independent Disks) realizes high
performance or fault tolerance, which are configured by arraying multiple
independent hard disk drives.
2 hard disk drives can be used to construct a RAID configuration
(RAID-1: mirroring or RAID-0: Striping).
When using RAID-1 (mirroring), the data is stored twice (once on each of
the HDDs) so that even if there are problems with one of the hard disk
drives, the other hard disk drive can be used to recover the data.
Please refer to the TOSHIBA RAID help for details.
■ By changing the RAID setting you are reconfiguring your hard disk.
Therefore, please make sure to make a backup copy of your data
before changing the RAID setting.
■ A power-on password can help restrict access to your data.
It can also help restrict access to System Setup, where some of your
computer’s configuration settings are kept.
If you do not have a power-on password set, someone with access to it
could
(i) set a power-on password, locking you out of your own computer, or
(ii) change your configuration settings, which could result in data loss.
We recommend that you consider using a power-on password.
