• Write Performance Margin
The “Write Performance Margin” is for controller to reserve n%
write margin AV stream recording. It is designed to eliminate
the frame drop and ensure to provide the smooth and stable
performance on the application.

4.8.3 HDD Power Management
Areca has automated the ability to manage HDD power based
on usage patterns. The “HDD Power Management” allows you
to choose a “Stagger Power On Control”, “Low Power Idle”, “Low
RPM” and completely “Spins Down Idle HDD”. It is designed to
reduce power consumption and heat generation on idle drives.
To set the HDD power management function, move the cursor to
the main menu and click the “HDD Power Management” link. The
“HDD Power Management” menu will show all items, and then
select the desired function.
