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:
The process automatically installs a driver that allows LaCie RAID Manager to detect the device and manage RAID arrays.
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 |
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.
Users with administrator privileges for the computer can launch LaCie RAID Manager without signing into the application.
A standard (non-adminstrator) user launching LaCie RAID Manager is prompted to sign in with administrator credentials. An administrator should launch the application to prepare the device for a standard user.
To change RAID levels, confirm that Rugged RAID Pro is connected to your computer and powered. You’ll need a thin, pointed object such as the end of a paperclip to confirm the RAID change.
