Manage RAID
LaCie RAID Manager manages the RAID configuration for your LaCie Rugged RAID Pro and provides important
firmware updates and notifications. You may have already installed LaCie RAID Manager as part of your initial
setup. If LaCie RAID Manager is not installed on your computer, you can download and install the app:
1. On the computer that will connect to the Rugged RAID Pro, go to www.lacie.com/support/lrm.
2. Download LaCie RAID Manager for Windows or Mac.
3. Launch the Installer.
4. Follow the on-screen instructions to complete the installation.
The process automatically installs a driver that allows LaCie RAID Manager to detect the device and manage
RAID arrays.
RAID levels
LaCie Rugged RAID Pro can be configured as RAID 0, RAID 1, or JBOD. 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
JBOD 100% None Varies 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.
JBOD—”JBOD” stands for “Just a Bunch of Disks”, meaning that your two drives have not been configured as
an array and operate as two independent disks.
