AV recording option is for video recording (no time limit), but if used in normal operation,
performance may be degraded. This new feature there are 4 options; Disabled, Mode1, Mode2
and Mode 3. Default value is Disabled. Our controller cache uses LRU method, there have no
special memory capacity reserved for read or write. The Mode 1, 2 and 3 are used to define the
command sorting method. The default sorting method is helpful for normal applications, but
not useful for AV applications, so we have defined three different sorting methods for these
special applications. To decide how to optimize AV stream recording parameter, you need to
adjust the Optimize AV Recording and Write Buffer Threshold during runtime.
•
Read Performance Margin
The “Read Performance Margin” is for controller to reserve n% read margin during AV stream
recording.
•
Write Performance Margin
The “Write Performance Margin” is for controller to reserve n% write margin AV stream
recording.
•
Read And Discard Parity Data
This function is used to determine if parity data is to be read and discarded.

BIOS Selection
It combines the “Legacy BIOS”, “UEFI BIOS” and “EFI BIOS” into a single BIOS, and provides BIOS
option in the GUI. In the previous version, Sans Digital provided separate BIOS files for each, and
need to manually flash it in. Now flashing BIOS for different BIOS type is no longer needed, just
make the BIOS selection in System Controls: Advance Configuration: BIOS Option.
The controller provides three BIOS options.
o
Legacy: for PC motherboards that are using regular BIOS boot.
o
UEFI: for PC motherboards using UEFI boot.
o
EFI: for Intel-based Mac boot Disable: disable controller BIOS at POST (set to 0xFF)
o
If BIOS is to be disabled --> All data are 0xFF

HDD Power Management
Sans Digital 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.
