and Mode 3. Default value is “Disabled”. Our controller cache
uses LRU method; there have no special memory capacity re-
served for read or write. The Mode 1, 2 and 3 are used to de-
fine the command sorting method. The default sorting method
is helpful for normal applications, but not useful for AV ap-
plications, 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. It is designed to
eliminate the frame drop and ensure to provide the smooth
and stable performance on the application.
• 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.
• Read And Discard Parity Data
This function is used to determine if parity data is to be read
and discarded. It is designed to eliminate the frame drop and
ensure to provide the smooth and stable performance on the
application.
• BIOS Selection
It combines the “Legacy BIOS” and “UEFI BIOS” and “EFI
BIOS” into a single BIOS, and provide BIOS option in the GUI.
In the old days, Areca provided separate BIOS files for each,
and need to manually flash it in. Now flashing BIOS for differ-
ent BIOS type is no longer needed, just make the BIOS selec-
tion in System Controls: Advance Configuration: BIOS Option.
The controller provides three BIOS options.
“Legacy” – for motherboards that are using regular BIOS boot.
“UEFI” – for motherboards (especially Intel’s motherboards)
using UEFI boot
“EFI” – for Intel based MacPro boot
“Disable” – disable controller BIOS at POST (set to 0xFF)
==> If BIOS is to be disabled --> All data are 0xFF
