Assign processing priorities

By default, the RAID processor for your device gives all actions equal priority. You can change the priority for specific activities—for example, you can give initialization a low priority while you are working during the day and a high priority during the night.

Use the sliders to make the preferred adjustments.

 Moving multiple sliders to High affects the performance of all arrays associated with the LaCie device.

Change Poll SMART status setting

SMART (Self-Monitoring, Analysis and Reporting Technology) is a hardware monitoring system that reports various indicators of drive reliability. When Poll SMART Status is enabled, LaCie RAID Manager gathers and reports information for each hard drive in the enclosure, including the model number, capacity and overall SMART status. SMART status should only be used for informational purposes when diagnosing hard drives.

 Enabling SMART status can have a negative affect upon performance.

When the option is enabled, you can view SMART details on each array:

  1. In the sidebar, open the Arrays menu.
  2. Click on an array to highlight it.
  3. In the SMART column, click Details.

Change Auto rebuild setting

When Auto rebuild is enabled, the device automatically rebuilds a degraded array once a spare hard drive is available. The rebuild cannot begin if there are no dedicated or global spare hard drives.

Change Audible alarm setting

When Audible alarm is enabled, the device emits audible warnings when encountering a critical event (for example, hard drive failure or high temperatures). See your device’s user manual for a list of audible warning conditions.

Audible alarm settings can also be accessed using the Device selector at the top of the page:

 LaCie 5big Thunderbolt 2—You must use the Device selector to change audible alarm settings.
